Clear, reliable communication is one of the most critical aspects of safe flying. Whether you’re a student pilot making your first radio calls or an experienced aviator coordinating with ATC in busy airspace, mastering aircraft radios and proper communication etiquette ensures both safety and professionalism.
Understanding Aircraft Radios
Aircraft radios are two-way communication devices that allow pilots to transmit and receive voice communications. They’re used for air traffic control (ATC), pilot-to-pilot coordination, and monitoring critical information like weather and airport advisories. Modern radios are typically VHF (Very High Frequency), covering the 118.000 to 136.975 MHz aviation band.
FAA Requirements
- Certification & Licensing: No individual license is required for domestic flights, but an FCC license is needed for international flights. Radios in certificated aircraft must also meet FAA Technical Standard Orders (TSO).
- Frequency Use: ATC assigns frequencies at towered airports, while the Common Traffic Advisory Frequency (CTAF) is used for self-announcing at non-towered airports.
-
Emergency Frequency:
121.5 MHzis reserved exclusively for distress and emergency calls.
Radio Communication Etiquette
Effective communication is more than knowing frequencies. It's about being clear, concise, and professional to ensure every message is understood.
Standard Phraseology
- “Say Again” instead of “Repeat”
- “Affirmative/Negative” instead of “Yes/No”
- “Roger” to acknowledge a message has been received
- “Wilco” to confirm you have received and will comply
Best Practices
- Listen before transmitting to avoid interrupting.
- Identify yourself clearly (type + tail number).
- Keep transmissions short and to the point.
- Stay calm under pressure to avoid confusion.
- Think before you speak; know your message first.

If you prioritize a lightweight design, superior audio clarity, and straightforward COM-only functionality for voice, the Icom IC-A25C-S is the perfect choice.
Frequently Asked Questions
Do I need a license to use a handheld aviation radio?
For flights within the U.S., you do not need a personal license to operate a VHF airband radio from inside an aircraft. However, the aircraft itself must have a valid radio station license if it flies internationally or communicates with foreign stations.
Can a handheld radio replace my panel radio?
No, handhelds are intended as a secondary or backup device only. They have lower power and less range than panel-mounted radios and are not TSO-certified for primary use. They are essential for emergencies and ground operations but are not a substitute for your main radio.
What’s the range of a handheld radio?
Range is dependent on altitude ("line of sight") and terrain. From the air, you can typically expect 5–10 miles of range, sometimes more at higher altitudes. On the ground, the range is much shorter, often just 1–3 miles due to obstructions.
Final Thoughts
Effective radio communication is a skill that grows with experience. By combining a solid understanding of FAA standards, practicing proper etiquette with resources like Say Again, Please, and equipping yourself with a reliable handheld radio, you will fly safer and communicate with unshakable confidence.
