An airport is one of the most communication-intensive working environments in the world.

Aircraft are:

• Arriving
• Departing
• Taxiing
• Being refuelled
• Loading passengers
• Loading baggage
• Receiving maintenance
• Being repositioned

At the same time, pilots, air traffic controllers and authorised ground personnel may need clear and immediate communication.

Ordinary mobile-phone calls are not designed to manage this kind of operational communication.

Aviation therefore uses dedicated airband radio communication.

But an airband radio should not be confused with an ordinary walkie-talkie.

Although both may look similar and both provide push-to-talk voice communication, aviation radios operate within specifically allocated aeronautical frequency bands and are designed around aviation communication requirements.

For businesses working in:

• Aviation
• Airports
• Aircraft maintenance
• Ground handling
• Flight schools
• General aviation
• Helicopter operations
• Aircraft support services

understanding the difference is essential.

This guide explains what an airband radio is, how aviation VHF communication works, who should use these radios, which features matter and what Indian businesses should consider before purchasing aviation communication equipment.

---

What Is an Airband Radio?

An airband radio is a radio transceiver designed to communicate on frequencies allocated for aeronautical communication.

The primary VHF aviation communications band internationally is approximately:

117.975 MHz to 137 MHz

ICAO describes this band as the principal VHF band used for air-ground and air-air voice and data communication, including airport, en-route, approach and landing operations.

In practical radio specifications, you will commonly see aviation communication equipment covering approximately:

118.000 MHz to 136.975/136.992 MHz

depending on equipment design and regional channelisation.

For example, Icom’s current IC-A16 aviation transceiver supports transmission across 118.000–136.99166 MHz and both 8.33 kHz and 25 kHz channel spacing.

These are therefore specialist aviation radios rather than conventional business walkie-talkies.

---

Airband Radio vs Normal Walkie-Talkie

This is the first distinction a buyer should understand.

A typical commercial walkie-talkie may operate in:

• VHF land-mobile frequencies
• UHF land-mobile frequencies
• PMR446
• DMR systems
• Licensed business-radio channels

An aviation radio operates in the aeronautical VHF communication band.

They are not interchangeable simply because both devices have:

• An antenna
• Push-to-talk button
• Speaker
• Microphone

The purpose, frequency allocation and technical design are different.

Feature	Airband Radio	Conventional Business Radio
Primary purpose	Aviation communication	Business/team communication
Typical band	Approx. 118–137 MHz aviation VHF	Various VHF/UHF business bands
Voice modulation	Primarily AM	Often FM or digital
Typical users	Pilots, ATC, authorised aviation personnel	Security, factories, hotels, warehouses
Channel planning	Aviation-specific	Business-specific
Regulatory requirements	Aviation/WPC rules apply	Depends on business radio system
Airport use	Aeronautical communications	Internal operational coordination

This last distinction is particularly important.

Not every employee working at an airport needs an airband radio.

---

Why Does Aviation Use AM Instead of FM?

Most conventional business walkie-talkies use:

• FM
• Digital modulation such as DMR

VHF aviation voice communication traditionally uses amplitude modulation (AM).

Airband radio specifications therefore commonly show emission designations associated with AM voice communication.

For example, the Icom IC-A16 specification lists AM-compatible emission formats for aviation communication.

Why does aviation continue to use AM?

One important operational characteristic is that when two aircraft transmit simultaneously on the same AM frequency, interference can often make users aware that multiple transmissions are occurring.

With certain FM systems, the stronger signal may capture the receiver and largely suppress the weaker transmission.

In aviation, knowing that another transmission occurred can itself be important.

But from a buyer’s point of view, the main thing to remember is simpler:

A normal VHF FM walkie-talkie is not an aviation airband transceiver merely because its frequency number looks similar.

The equipment must actually be designed for aviation communication.

---

Who Uses Airband Radios?

Several aviation roles may require aeronautical radio communication.

---

Pilots

Pilots use aviation radios to communicate with:

• Air traffic control
• Ground control
• Tower
• Approach
• Departure
• Flight information services
• Other appropriate aeronautical stations

Aircraft normally contain installed communication radios, but handheld aviation radios can also provide useful portable or backup communication in appropriate authorised applications.

---

Air Traffic Controllers

ATC communication is one of the most obvious uses of aviation radio.

Controllers coordinate aircraft during:

• Ground movement
• Take-off
• Departure
• En-route operations
• Approach
• Landing

The aeronautical VHF communications band is designed specifically to support safety and regularity of flight.

---

Ground-to-Air Aviation Personnel

Certain authorised airport personnel may also require communication with aircraft.

Possible applications include:

• Ground operations
• Ramp coordination
• Aircraft movement support
• Maintenance personnel
• Aviation service providers

For this reason, manufacturers offer radios specifically described as ground-to-air aviation radios.

Icom, for example, positions its IC-A16 as a VHF airband transceiver designed for airside ground crews providing aviation services.

---

Aircraft Maintenance Teams

Maintenance engineers may require aviation communication equipment during:

• Aircraft testing
• Ground checks
• Maintenance coordination
• Certain operational procedures

However, frequency use and operator requirements should always follow the applicable aviation and telecommunications regulations.

---

Flight Schools

Flight-training organisations may use aviation radios for:

• Instructor communication
• Flight operations
• Dispatch coordination
• Training aircraft support

Handheld aviation radios can also be useful as authorised backup equipment.

---

General Aviation

Private aircraft owners, flying clubs and general aviation operators often use portable aviation radios because they can provide:

• Backup communication
• Portable ground communication
• Flight-line communication

provided that use complies with the applicable regulatory requirements.

---

Airband Radio Does Not Mean “Airport Walkie-Talkie”

This distinction is worth emphasising.

An airport may contain thousands of employees.

That does not mean thousands of employees should be communicating on aeronautical frequencies.

Consider:

Baggage Team

May use a conventional business radio system.

Airport Security

May use a licensed professional DMR system.

Housekeeping

May use another operational radio group.

Engineering

May use conventional business radio channels.

Authorised aviation personnel communicating with aircraft

May require an airband system.

These communication requirements should be separated properly.

Aviation frequencies are not simply general-purpose channels for airport staff.

---

What Frequencies Do Airband Radios Use?

International aeronautical VHF communication primarily occupies:

117.975–137 MHz.

ICAO describes this as the main line-of-sight air-ground communications band used at airports and throughout multiple phases of flight.

Individual frequencies inside the band are assigned for different aeronautical services.

Depending on jurisdiction and airport, these may support functions such as:

• Tower
• Ground
• Approach
• Departure
• Flight information
• Aeronautical operational communication

Users should never simply choose an unused-looking aviation frequency and begin transmitting.

Frequency assignment and use are controlled.

---

The Importance of 121.5 MHz

One frequency that many people associate with aviation is:

121.5 MHz

This is the internationally recognised aeronautical emergency frequency.

ICAO’s current spectrum policy specifically maintains provisions relating to the 121.5 MHz emergency channel.

This frequency should obviously not be treated as a casual communication channel.

Professional airband radios may provide easy emergency-frequency access, but transmission must follow appropriate aviation procedures.

---

What Is 25 kHz Channel Spacing?

Radio channels cannot simply be placed infinitely close together.

Traditional aeronautical VHF communication has widely used:

25 kHz channel spacing.

This means channels are separated according to an organised frequency plan to prevent adjacent-channel interference.

Many aviation radios continue to support 25 kHz channel spacing.

---

What Is 8.33 kHz Channel Spacing?

As aviation communication demand increased, some regions introduced narrower:

8.33 kHz channel spacing

to create additional usable communication channels inside the same frequency band.

Modern aviation radios may therefore support:

• 25 kHz
• 8.33 kHz

Icom’s IC-A16 and IC-A25 aviation radios, for example, support both channel-spacing schemes depending on version and market.

A buyer should therefore verify the channel-spacing requirements applicable to the region and operation where the radio will be used.

---

8.33 kHz vs 25 kHz: Why Buyers Should Care

Imagine purchasing an airband radio that cannot operate with the channelisation required by your aviation environment.

Even if the radio otherwise looks excellent, it may not be suitable.

Therefore, always confirm:

1. Frequency coverage
2. Channel spacing
3. Country/version
4. Certification
5. Intended operational use

before ordering equipment.

---

Airband Communication Is Mostly Line-of-Sight

VHF aviation communication generally behaves as line-of-sight radio.

That means coverage depends strongly on:

• Antenna height
• Aircraft altitude
• Terrain
• Buildings
• Obstructions

This explains an interesting aviation-radio characteristic:

A handheld radio on the ground may have relatively limited communication distance.

But communication with an aircraft thousands of feet above the ground can be possible over much greater distances because there are fewer obstructions between antennas.

---

Why Aircraft Altitude Improves Radio Range

Consider two radios on the ground.

Between them may be:

• Buildings
• Hills
• Trees
• Airport structures

Now place one radio several thousand feet in the air.

The signal path becomes much clearer.

This is why aviation communication range should not be judged using the same assumptions as:

• Warehouse radios
• Hotel radios
• Security walkie-talkies

The operating environment is fundamentally different.

---

Can an Airband Handheld Replace an Aircraft Radio?

It should not automatically be considered a replacement for certified installed aircraft communication equipment.

Handheld aviation radios are commonly useful for purposes such as:

• Portable ground operation
• Backup communication
• Aviation support activities
• Appropriate general aviation use

But aircraft equipment requirements depend on:

• Aircraft type
• Operating rules
• Aviation authority requirements
• Installation/certification requirements

A business should therefore purchase aviation radios for the application they are specifically approved and intended to perform.

---

The Most Important Airband Radio Features

When comparing aviation handheld radios, several specifications matter much more than appearance.

---

1. Audio Output

Airports are noisy.

Ground personnel may work around:

• Turbine engines
• Auxiliary power units
• Ground-support equipment
• Vehicles
• Baggage equipment
• Wind
• Aircraft movement

A quiet radio may be almost useless.

This is why professional aviation handheld manufacturers often emphasise audio power.

For example, Icom’s IC-A16 provides a 1500 mW speaker output, specifically targeting clear communication in noisy airport environments.

For ground staff, this can matter as much as RF output power.

---

2. Battery Life

Aviation personnel may work extended shifts away from charging stations.

Look for:

• High-capacity battery
• Realistic runtime
• Spare-battery availability
• Charging options

Icom specifies approximately 17 hours of operation for the IC-A16 using its BP-280 battery under a 5-5-90 test cycle with Bluetooth and backlight off.

As with conventional radios, real battery life depends on actual usage.

---

3. Ruggedness

Airside equipment experiences demanding conditions.

A radio may face:

• Rain
• Dust
• Drops
• Heat
• Cold
• Continuous handling

Professional aviation radios should therefore be evaluated for:

• IP rating
• Environmental testing
• Mechanical durability

The IC-A16, for example, is specified with IP67/54 protection depending on the relevant test aspect/version and MIL-STD-810-G environmental testing.

---

4. Display Visibility

Aviation operations occur:

• In bright sunlight
• At night
• Inside hangars
• Around floodlit aprons

The display therefore needs to remain readable under very different lighting conditions.

Useful features include:

• High-contrast LCD
• Backlighting
• Key illumination
• Large frequency display

Icom’s higher-end IC-A25 uses a 2.3-inch high-visibility LCD designed for readability in direct sunlight.

---

5. Direct Frequency Entry

Aviation users often need to move between known frequencies quickly.

A keypad can allow users to enter the required frequency directly instead of stepping through channels.

Whether this matters depends on the user.

Ground Employee

May only use a limited number of programmed frequencies.

Pilot

May benefit greatly from faster direct frequency access.

---

6. Memory Channels

Modern aviation radios can store frequently used frequencies.

For example:

Icom IC-A16

Up to 200 memory channels.

Icom IC-A25

Up to 300 memory channels, depending on model/version.

For organisations working repeatedly at the same airports or within the same operational network, memory channels can reduce user error and improve convenience.

---

7. Emergency Frequency Access

Some aviation radios provide a dedicated method to reach the emergency frequency quickly.

This can be useful in genuine aviation emergencies.

However, this should not be confused with the programmable emergency buttons found on professional security radios.

The operational concept is different.

---

8. Noise Reduction

Airside noise can be extreme.

Useful aviation-radio audio technologies may include:

• Automatic noise limiting
• Clear speaker output
• Headset compatibility
• Side tone

Icom’s IC-A16, for example, includes an Auto Noise Limiter (ANL) designed to reduce pulse-type noise.

---

9. Aviation Headset Compatibility

A pilot or ground worker may need the radio connected to an aviation headset.

Headset support can provide:

• Better intelligibility
• Hands-free or easier operation
• Hearing protection compatibility
• Microphone integration

Before purchasing, confirm:

• Connector type
• Adapter requirement
• Headset compatibility
• PTT arrangement

The IC-A16 supports third-party aviation headsets through an optional headset adapter.

---

10. Bluetooth

Selected aviation radios now offer Bluetooth support.

This can help with:

• Wireless headsets
• Hands-free operation

depending on the radio version.

The IC-A16 and selected IC-A25 versions offer Bluetooth capabilities.

However, an airport buyer should confirm actual compatible accessories rather than assuming every Bluetooth device will work.

---

11. GPS and Navigation Features

Some advanced handheld aviation radios include built-in navigation capabilities.

For example, the Icom IC-A25N provides:

• Built-in GPS
• GLONASS/SBAS support
• Direct-To navigation
• Flight-plan navigation
• Stored waypoints

depending on version.

These features can be valuable for pilots.

They may be unnecessary for a ground worker who only needs reliable voice communication.

This illustrates a principle that applies throughout professional radio purchasing:

Do not pay for advanced functions unless the user will actually benefit from them.

---

Ground-to-Air Radio vs Pilot Aviation Radio

Not all airband users need the same product.

Ground-to-Air User

Typical priorities:

• Loud audio
• Simple operation
• Long battery life
• Ruggedness
• Easy channel selection
• Headset compatibility

Pilot

May additionally value:

• Large display
• Direct keypad entry
• Navigation functions
• GPS
• Larger memory capacity
• Emergency-frequency access
• Flight-planning capability

A manufacturer may therefore offer several airband models for different aviation roles.

---

Example: Icom IC-A16

The Icom IC-A16 represents the straightforward professional ground-to-air approach.

Key specifications include:

• VHF aviation communication
• 118.000–136.99 MHz transmission range
• 8.33/25 kHz channel spacing
• 1500 mW audio output
• Approximately 17-hour battery life
• 200 memory channels
• Bluetooth on applicable versions
• Rugged environmental protection
• Headset support through compatible accessories

Icom specifically describes it as suitable for airside ground crews.

This makes it a strong example of the kind of radio a professional aviation service business might evaluate.

---

Example: Icom IC-A25

The Icom IC-A25 series represents a more sophisticated aviation handheld platform.

Depending on model/version, features can include:

• Approximately 6 W PEP RF output
• 2.3-inch display
• 8.33/25 kHz channel spacing
• Bluetooth
• GPS
• Waypoint navigation
• Flight-plan navigation
• Large memory capacity
• IP57 construction

The IC-A25N/NE models add navigation functionality not required by every ground user.

So the IC-A16 vs IC-A25 decision should not simply become:

“Which is more expensive?”

It should be:

“Does this user require aviation navigation functions or primarily communication?”

---

Airband Radios for Airport Ground Handling

Ground handling involves rapid coordination around aircraft.

Activities may include:

• Baggage loading
• Catering
• Aircraft servicing
• Ramp operations
• Pushback
• Ground equipment coordination

But aviation companies should distinguish between two communication requirements.

Communication With Aircraft / Aeronautical Stations

May require appropriate airband radio equipment and authorisation.

Internal Team Communication

May be better handled through:

• Conventional two-way radios
• DMR
• PoC systems

This prevents unnecessary use of aeronautical channels for ordinary operational traffic.

---

Airband Radios for Aircraft Maintenance

Aircraft maintenance organisations may require radio communication for:

• Ground testing
• Engine-related procedures
• Coordination with authorised aviation stations
• Aircraft movement support

Priorities include:

• Loud audio
• Headset compatibility
• Ruggedness
• Battery endurance

Maintenance organisations should define exactly who needs aeronautical-frequency access before purchasing equipment.

---

Airband Radios for Flying Schools

A flight school may have several communication roles:

Aircraft Pilots

Need aviation communication.

Flight Operations

May require appropriate aviation communication depending on responsibility.

Administrative Team

Does not necessarily need airband access.

Ground Support Staff

Requirements depend on actual aviation duties.

A mixed communications fleet may therefore make more sense than issuing the same radio to every employee.

---

Airband Radio vs PoC

A PoC radio cannot simply replace aeronautical VHF communications between aircraft and ATC.

PoC uses:

• Cellular networks
• Wi-Fi
• Internet-based communication

Airband uses dedicated aeronautical radio spectrum.

However, aviation businesses can use both technologies for different purposes.

For example:

Airband

Aircraft-related authorised communication.

PoC

Operations managers across several airport facilities.

DMR

Baggage, engineering and security teams within the airport.

A modern airport communications system can therefore contain several complementary platforms.

---

Airband Radio vs DMR

These technologies should not be confused.

Airband

• Aviation VHF
• AM voice
• Aircraft-related communication

DMR

• Professional digital land-mobile radio
• Used by factories, security, logistics and other ground operations
• Digital voice/data capability

A DMR radio cannot communicate with an aircraft using standard VHF airband merely because both are “professional radios.”

---

Do You Need a Licence to Use Airband Radio in India?

This is particularly important for Indian buyers.

Aeronautical radio use in India is regulated through the Wireless Planning & Coordination Wing of the Department of Telecommunications.

The DoT currently describes the Radio Telephone Operator’s Restricted (Aeronautical), or RTR-A, as the certification required for individuals operating radio communication equipment in aeronautical services, including pilots, ATC personnel and aeronautical radio operators.

India also has WPC authorisation mechanisms covering aeronautical radio stations and aero-mobile communication equipment.

Therefore:

An airband handheld should not be treated like an ordinary license-free walkie-talkie.

Owning appropriate equipment and being legally authorised to transmit are separate questions.

---

Listening vs Transmitting

Aviation radios may provide receive capability outside or beyond the frequencies on which they transmit.

But users should not assume that because a device can receive a frequency, they are automatically authorised to transmit on it.

Transmit authority depends on:

• User role
• Station authorisation
• Frequency assignment
• Applicable aviation and telecom rules

Businesses should confirm the exact regulatory requirements before deployment.

---

Why Buying Cheap Programmable Radios Is Risky

Online marketplaces may contain radios claiming extremely broad frequency coverage.

For aviation communication, this can be a poor approach.

A professional buyer should look for equipment specifically designed for airband use.

Important reasons include:

• Correct AM modulation
• Correct frequency stability
• Aviation channel spacing
• Appropriate controls
• Aviation headset compatibility
• Regulatory compliance
• Reliable audio
• Proper filtering

A general-purpose programmable radio should not automatically be considered suitable merely because it can be programmed near an aviation frequency.

---

What Should an Aviation Business Ask Before Buying?

Before requesting a quotation, answer these questions.

---

1. Who Will Use the Radio?

Pilot?

Ground staff?

Maintenance engineer?

Flight-school employee?

Different roles require different radios.

---

2. Will the User Transmit or Only Monitor?

Transmit requirements introduce additional regulatory considerations.

---

3. Which Frequencies Are Required?

Confirm the authorised aviation frequencies and operating environment.

---

4. Do You Need 8.33 kHz?

Confirm the applicable channel-spacing requirement.

Do not assume every country or operation uses exactly the same scheme.

---

5. How Noisy Is the Environment?

For airport ground crews, loud audio can be critical.

---

6. Will Headsets Be Used?

Confirm compatibility before purchasing radios and accessories.

---

7. How Long Are the Shifts?

Choose battery capacity accordingly.

---

8. Will the Radio Be Used Outdoors?

Check:

• IP rating
• Weather resistance
• Temperature range

---

9. Does the User Need GPS or Navigation?

Pilots may benefit.

Ground employees may not.

---

10. Which Regulatory Authorisations Apply?

This should be determined before deployment—not after equipment is purchased.

---

What to Look for in an Airband Radio Supplier

A professional aviation-radio supplier should do more than provide a box.

They should be able to help confirm:

• Appropriate radio category
• Model suitability
• Frequency range
• Channel spacing
• Accessories
• Battery options
• Headset compatibility
• Programming requirements
• Regulatory considerations

A buyer should be cautious when the entire sales conversation consists of:

“This radio has 10 km range.”

Aviation communications are much more specialised than ordinary consumer walkie-talkies.

---

Range Is Not the Only Specification That Matters

As with conventional two-way radios, buyers frequently ask how far an airband radio can communicate.

Range depends on:

• Antenna
• RF output
• Terrain
• User height
• Aircraft altitude
• Buildings
• Receiver performance

Because aviation VHF is strongly line-of-sight, communicating with an aircraft at altitude can produce very different results from communicating between two people standing on the ground.

Manufacturers may therefore quote radio power, but businesses should avoid translating that directly into a guaranteed number of kilometres.

---

High Power Does Not Automatically Mean Better Aviation Communication

A stronger transmitter can help within the permitted system design.

But it cannot solve:

• Poor antenna
• Severe terrain obstruction
• Incorrect frequency
• Incompatible equipment
• Regulatory misuse

Professional aviation communication depends on the complete radio system and operating procedure.

---

Battery Planning for Aviation Ground Teams

Airport ground operations may run continuously.

A sensible radio-management plan should include:

• Fully charged radios at shift start
• Spare batteries where appropriate
• Multi-unit chargers
• Battery rotation
• Equipment inspection

An airband radio with excellent specifications becomes useless if an employee receives it with 20% battery remaining.

Fleet management matters.

---

Headsets Can Be More Important Than Speaker Volume

A loud speaker is valuable.

But some environments are so noisy that a compatible aviation headset is a better solution.

Headsets can improve:

• Speech intelligibility
• User comfort
• Microphone positioning
• Hands-free workflow

Ensure that the selected headset and adapter are designed to operate with the radio.

---

Don’t Forget Night Operations

Airports operate around the clock.

Night users benefit from:

• Backlit display
• Illuminated keypad
• Simple channel recall
• Clear controls

The radio should remain easy to operate without requiring the user to stop working and inspect tiny buttons under poor lighting.

---

Common Mistakes When Buying Airband Radios

Mistake 1: Treating Airband Like a Normal Walkie-Talkie

It is specialised aviation communication equipment.

---

Mistake 2: Buying Only by Range

Coverage is only one factor.

---

Mistake 3: Ignoring Channel Spacing

Confirm 25 kHz/8.33 kHz requirements.

---

Mistake 4: Buying a Complex Navigation Radio for a Ground Worker

Pay for capabilities the user needs.

---

Mistake 5: Giving Airband Radios to Every Airport Employee

Most internal operational communication belongs on other communication systems.

---

Mistake 6: Ignoring Operator Authorisation

Transmission on aviation frequencies is regulated.

---

Mistake 7: Buying Generic Programmable Radios

Use appropriate aviation equipment.

---

Mistake 8: Ignoring Audio

Airport noise can make a technically functional radio operationally useless.

---

Mistake 9: Forgetting Headset Compatibility

Check before buying accessories.

---

Mistake 10: Ignoring Battery Management

Aviation operations may run around the clock.

---

Airband Radio Buyer Checklist

Before purchasing, confirm:

• Aviation-specific VHF radio
• Correct transmit frequency range
• Correct receive range
• Required channel spacing
• AM aviation communication support
• Sufficient speaker audio
• Battery runtime
• Spare batteries available
• Charging equipment available
• Outdoor/weather resistance
• Headset compatibility
• Display visibility
• Memory channels
• Emergency-frequency features if required
• GPS/navigation only if useful
• Appropriate Indian regulatory permissions
• Supplier programming/support

If several of these questions remain unanswered, the purchasing decision is not finished.

Frequently Asked Questions

What is an airband radio?

An airband radio is a radio designed to communicate on frequencies allocated for aeronautical communication, primarily in the VHF aviation band around 118–137 MHz.

What frequency does aviation radio use?

ICAO identifies 117.975–137 MHz as the principal VHF aeronautical air-ground communications band.

Can a normal walkie-talkie communicate with an aircraft?

Ordinary business walkie-talkies are not designed as aviation airband transceivers. Aviation communication requires appropriate equipment operating with the correct frequency, modulation and regulatory authorisation.

Is airband AM or FM?

Conventional VHF aviation voice communication primarily uses AM.

Why does aviation use AM?

AM has historical and operational advantages for aviation communication, including how simultaneous transmissions can be perceived. It is also the internationally established standard for conventional VHF aviation voice communication.

What is 121.5 MHz?

121.5 MHz is the international aeronautical emergency frequency.

What is 8.33 kHz channel spacing?

It is narrower aviation-frequency channelisation that allows more communication channels to fit within the available VHF aviation spectrum.

Do all airband radios support 8.33 kHz?

No. Buyers should check the radio’s specifications. Modern models such as the Icom IC-A16 support both 8.33 and 25 kHz spacing.

What is the best airband radio for ground crews?

Ground crews should prioritise loud audio, straightforward controls, long battery life, ruggedness and headset compatibility. A model such as the Icom IC-A16 is specifically marketed for airside ground operations.

What is the difference between Icom IC-A16 and IC-A25?

The IC-A16 focuses strongly on straightforward ground-to-air communication, while selected IC-A25 versions add a larger display, GPS and aviation navigation functions.

How long does an airband radio battery last?

It depends on model and usage. Icom specifies around 17 hours for the IC-A16 with its supplied high-capacity battery under the stated 5-5-90 test conditions.

Are airband radios waterproof?

Some professional models provide meaningful ingress protection. Buyers should check the exact IP rating rather than assuming all aviation radios are waterproof.

Do I need a licence to operate an airband radio in India?

Aeronautical radio transmission in India is regulated. The DoT/WPC issues the RTR-A certification for applicable aeronautical radio operators, and relevant station/frequency authorisations may also apply.

Can airport security use airband radios?

Airport security normally has its own operational communication requirements and does not automatically need aeronautical-frequency access. Conventional licensed radio or digital systems are generally more appropriate unless the user’s authorised duties specifically require aviation communication.

Can airband radios be used for airport housekeeping?

Airband frequencies should not be treated as general-purpose airport employee channels. Internal operational communication should use an appropriate business communication system.

Do airband radios work inside airport terminals?

They can receive/transmit according to normal VHF propagation limitations, but building structures can reduce coverage. Airband systems should not be selected as a general indoor staff communication solution merely because the business operates at an airport.

Final Thoughts

Airband radios occupy a very specific place in professional communication.

They are not simply expensive VHF walkie-talkies.

They are aviation communication tools designed around internationally allocated aeronautical frequencies and operational requirements.

The main VHF aviation communication band around 118–137 MHz supports communication that plays a direct role in the safety and regularity of flight.

That is why selecting an aviation radio requires more care than buying a general-purpose business handset.

Businesses should evaluate:

• Who will use the radio
• Whether transmission is actually required
• Which aviation frequencies are authorised
• Channel spacing
• Audio requirements
• Battery endurance
• Environmental protection
• Headset compatibility
• Navigation requirements
• Indian licensing and operator requirements

A ground worker who only needs clear communication may benefit from a straightforward aviation transceiver.

A pilot may value GPS and navigation functionality.

A baggage team or airport security unit may not need an airband radio at all and may be better served by DMR or another professional communications platform.

Choosing the right technology for each user is more important than trying to make one radio system serve every department.

For Indian aviation businesses, Electrosonic Technologies can help evaluate professional airband communication requirements alongside conventional two-way radio and PoC solutions so that aircraft-related communication and internal operational communication are handled by the appropriate systems.
