1. Why Radio Communication Matters
Aviation radio communication is not optional — it is a safety system. Clear, standard phraseology prevents misunderstandings that can lead to runway incursions, midair conflicts, and controlled flight into terrain. The NTSB has cited communication errors as a contributing factor in hundreds of incidents and accidents.
Under 14 CFR 91.129 and 91.130, two-way radio communication is required when operating in Class B, C, and D airspace. Even in Class E and G airspace, radio calls at uncontrolled airports are strongly recommended by the FAA (AIM 4-1-9).
Good radio technique marks the difference between a confident, professional pilot and one who sounds unsure. Controllers appreciate concise, correct transmissions — and they will be more likely to accommodate your requests when you communicate clearly.
2. Radio Equipment Basics
Most training aircraft have at least one VHF communication radio (COM1). Many have two (COM1 and COM2), allowing you to monitor one frequency while actively communicating on another — for example, listening to ATIS on COM2 while talking to Tower on COM1.
PTT (Push-to-Talk)
A button on the yoke or control stick. Press and hold to transmit, release to listen. Wait a full second after pressing before speaking to avoid clipping your first words.
Squelch
A filter that removes static background noise. If properly set, you hear silence until someone transmits. If you cannot hear ATC, check that squelch is not set too high.
Volume
Ensure COM volume is up before departure. A common student mistake is having the volume turned down and thinking the radio is broken.
Active vs. Standby
Most radios have an active frequency (in use) and a standby frequency. Dial the new frequency into standby, then press the flip/swap button to make it active.
TIP Frequency Range
3. Who You're Talking To
A controlled airport has multiple ATC facilities, each responsible for a different phase of your flight. Understanding who does what helps you contact the right controller at the right time.
4. The Basic Format: WHO-WHO-WHERE-WHAT
Every initial call to ATC follows the same four-part structure. Memorize it and you will never freeze on the mic.
1
WHO you're calling
"Springfield Tower"
2
WHO you are
"Cessna 934AB"
3
WHERE you are
"10 south at 3,500"
4
WHAT you want
"Inbound for landing"
PILOT: "Springfield Tower, Cessna niner-three-four-Alpha-Bravo, 10 miles south at three thousand five hundred, inbound for landing with information Delta."
ATC: "Cessna 934AB, Springfield Tower, report left base runway 2-0."
PILOT: "Report left base runway 2-0, Cessna 934AB."
KEY RULE Readback Requirements
5. Phonetic Alphabet & Numbers
The NATO/ICAO phonetic alphabet eliminates ambiguity caused by similar-sounding letters. Every pilot must know it cold. Numbers also have specific pronunciation rules in aviation.
| Number | Spoken As | Note |
|---|---|---|
| 0 | ZEE-RO | |
| 1 | WUN | |
| 2 | TOO | |
| 3 | TREE | Not 'three' |
| 4 | FOW-ER | Not 'four' |
| 5 | FIFE | Not 'five' |
| 6 | SIX | |
| 7 | SEV-EN | |
| 8 | AIT | Not 'eight' |
| 9 | NIN-ER | Not 'nine' |
Altitudes are spoken digit-by-digit for thousands: "three thousand five hundred" (3,500), "one-zero thousand" (10,000), "flight level tree-fife-zero" (FL350). Frequencies are spoken with each digit: "wun-too-wun-point-niner" (121.9).

Practice Phonetic Alphabet →6. Essential Phraseology — Phase by Phase
The following dialogues cover every phase of a typical VFR and IFR flight at a controlled airport. Study the flow, not just the words.
6a. Startup & Taxi
At busy airports, you may need to request startup clearance from Ground. At most GA airports, simply contact Ground when ready to taxi.
PILOT: "Metro Ground, Skyhawk niner-three-four-Alpha-Bravo at the FBO, VFR to Riverside, request taxi with information Bravo."
ATC: "Skyhawk 4AB, Metro Ground, taxi to runway 2-8 via Alpha, hold short runway 1-0."
PILOT: "Taxi to runway 2-8 via Alpha, hold short runway 1-0, Skyhawk 4AB."
CRITICAL Hold Short = Read Back Required
6b. Takeoff Clearance
PILOT: "Metro Tower, Skyhawk niner-three-four-Alpha-Bravo, runway 2-8, ready for departure, VFR southbound."
ATC: "Skyhawk 4AB, runway 2-8, cleared for takeoff, wind 2-6-0 at 8."
PILOT: "Cleared for takeoff, runway 2-8, Skyhawk 4AB."
Note: say "ready for departure" — not "ready for takeoff." The word "takeoff" is reserved for the actual clearance to avoid confusion.
6c. Departure — VFR
ATC: "Skyhawk 4AB, frequency change approved, squawk VFR. Good day."
PILOT: "Squawk VFR, good day, Skyhawk 4AB."
6c (IFR). Departure — IFR
ATC: "Skyhawk 4AB, contact Departure on 124.0."
PILOT: "124.0, Skyhawk 4AB."
PILOT: "Metro Departure, Skyhawk niner-three-four-Alpha-Bravo, one thousand seven hundred climbing three thousand."
ATC: "Skyhawk 4AB, Metro Departure, radar contact. Climb and maintain four thousand."
PILOT: "Climb and maintain four thousand, Skyhawk 4AB."
6d. En Route Position Reports
VFR position reports are used when receiving flight following from Center or Approach. IFR position reports are required in non-radar environments.
PILOT: "Kansas City Center, Skyhawk niner-three-four-Alpha-Bravo, request VFR flight following to Riverside at four thousand five hundred."
ATC: "Skyhawk 4AB, Kansas City Center, squawk 4-5-2-1, altimeter 3-0-0-2."
PILOT: "Squawk 4-5-2-1, altimeter 3-0-0-2, Skyhawk 4AB."
PILOT: "Seattle Radio, Bonanza two-one-four-Papa-Golf, position report."
PILOT: "Two-one-four-Papa-Golf, CREAK intersection at 1-5, flight level zero-six-zero, estimating TUMWA at 3-2, CHINS next."
6e. Approach & Landing
PILOT: "Riverside Tower, Skyhawk niner-three-four-Alpha-Bravo, 8 miles north at three thousand, inbound for landing with information Echo."
ATC: "Skyhawk 4AB, Riverside Tower, enter right base runway 9, number 2 following a Cherokee on a 3-mile final. Report the Cherokee in sight."
PILOT: "Right base runway 9, number 2, looking for the Cherokee, Skyhawk 4AB."
PILOT: "Skyhawk 4AB, traffic in sight."
ATC: "Skyhawk 4AB, runway 9, cleared to land."
PILOT: "Cleared to land, runway 9, Skyhawk 4AB."
6f. Go-Around
A go-around can be initiated by the pilot or directed by ATC. Always fly the airplane first, then communicate.
PILOT: "Riverside Tower, Skyhawk 4AB, going around."
ATC: "Skyhawk 4AB, roger, make left traffic runway 9, climb runway heading."
PILOT: "Left traffic runway 9, Skyhawk 4AB."
ATC: "Skyhawk 4AB, go around, traffic on the runway. Climb runway heading, maintain 2,000."
PILOT: "Going around, runway heading, maintain 2,000, Skyhawk 4AB."
6g. Emergency Calls — 121.5 MHz
If you are already talking to ATC, declare on the current frequency. If not, tune 121.5 MHz — monitored by all ATC facilities and many aircraft. Set transponder to 7700.
PILOT: "MAYDAY, MAYDAY, MAYDAY. Springfield Approach, Cessna niner-three-four-Alpha-Bravo, engine failure, 5 miles east of Springfield at two thousand, two souls on board, three hours fuel, looking for a field to land."
ATC: "Cessna 934AB, Springfield Approach, roger your MAYDAY. Squawk 7-7-0-0. Springfield Airport is 5 miles to your west, runway 2-0. Do you have the airport in sight?"
PILOT: "Squawk 7-7-0-0, looking for the airport, Cessna 934AB."
PILOT: "PAN-PAN, PAN-PAN, PAN-PAN. Kansas City Center, Bonanza two-one-four-Papa-Golf, alternator failure, requesting vectors to nearest airport for precautionary landing. Estimate 30 minutes battery remaining."
ATC: "Bonanza 214PG, roger your PAN-PAN. Turn left heading 3-6-0, Columbia Regional Airport 22 miles north. Descend and maintain 3,000."
PILOT: "Left 3-6-0, down to 3,000, Bonanza 214PG."
REMEMBER Mayday vs. Pan-Pan
7. How to Listen to and Copy ATIS
ATIS (Automatic Terminal Information Service) is a continuous recorded broadcast updated hourly or when conditions change significantly. Always listen to ATIS before contacting any controller — it saves radio time and tells ATC you are prepared.
Sample ATIS — Write This Down:
"Springfield Municipal Airport, information Delta. Time 1-8-5-3 Zulu. Wind 2-6-0 at 8. Visibility 10. Sky clear. Temperature 2-2, dewpoint 1-4. Altimeter 3-0-0-2. Landing and departing runway 2-0. Notices to airmen: taxiway Bravo closed between Alpha and Charlie. Advise on initial contact you have information Delta."
Information Letter: Delta (D)
Tell ATC which ATIS you heard
Wind: 260 at 8 kts
Runway selection, crosswind calc
Visibility: 10 SM
VFR/IFR determination
Ceiling/Sky: Clear
Cloud clearance requirements
Temp/Dewpoint: 22/14 C
Density altitude, fog risk
Altimeter: 30.02 inHg
Set before entering Class D/C/B
Active Runway: 20
Plan your pattern entry
NOTAMs: TWY B closed
Taxi route planning
SHORTCUT ATIS Shorthand
8. Uncontrolled Airport Communications (CTAF)
Most airports in the US are non-towered. At these airports, pilots self-announce their position and intentions on the CTAF (Common Traffic Advisory Frequency). There is no controller — traffic separation is your responsibility.
The CTAF is published on sectional charts and in the Chart Supplement. Common CTAF frequencies: 122.7, 122.8, 122.725, 122.975, and 123.0 MHz.
PILOT: "Pine Valley traffic, Skyhawk niner-three-four-Alpha-Bravo, 10 miles to the south at three thousand, inbound for landing runway 3-6, Pine Valley."
PILOT: "Pine Valley traffic, Skyhawk 4AB, entering left downwind runway 3-6, Pine Valley."
PILOT: "Pine Valley traffic, Skyhawk 4AB, turning left base runway 3-6, Pine Valley."
PILOT: "Pine Valley traffic, Skyhawk 4AB, final runway 3-6, full stop, Pine Valley."
PILOT: "Pine Valley traffic, Skyhawk 4AB, clear of runway 3-6, taxiing to parking, Pine Valley."

9. IFR Communications
IFR flights require precise communication with ATC from clearance to cancellation. The most critical skill is copying and reading back your IFR clearance using the CRAFT format.

PILOT: "Metro Clearance, Bonanza two-one-four-Papa-Golf, IFR to Riverside, ready to copy."
ATC: "Bonanza 214PG, cleared to Riverside Airport as filed. Climb and maintain 4,000, expect 6,000 one-zero minutes after departure. Departure frequency 124.0. Squawk 4-5-2-1."
PILOT: "Bonanza 214PG is cleared to Riverside as filed, climb and maintain 4,000, expect 6,000 in 1-0 minutes, departure 124.0, squawk 4-5-2-1."
ATC: "Bonanza 214PG, readback correct. Contact Ground 121.7 when ready to taxi."
PILOT: "Ground on 121.7, Bonanza 214PG."
IFR Readback Requirements
Under IFR, you must read back all of the following:
- Clearance limits and route amendments
- Altitude assignments and altitude restrictions
- Heading assignments and vectors
- Approach clearances and approach instructions
- Runway assignments
- Hold-short instructions
- Altimeter settings
- Frequency changes
ATC: "Bonanza 214PG, 8 miles from RIDGY. Turn left heading 3-6-0, maintain 3,000 until established on the localizer. Cleared ILS runway 2-0 approach."
PILOT: "Left heading 3-6-0, maintain 3,000 until established, cleared ILS runway 2-0, Bonanza 214PG."
10. Common Mistakes Beginners Make
Saying "take off" when you mean "departure"
Only ATC uses the word "takeoff" — in a clearance. Say "ready for departure" to avoid confusion.
Stepping on other transmissions
Listen for a full second of silence before pressing PTT. If you hear a squelch break, wait.
Not writing down the clearance
Use a kneeboard and the CRAFT format. Asking ATC to repeat wastes time.
Using "roger" as a readback
"Roger" only means you received the message. ATC needs to hear the clearance read back word-for-word.
Talking too fast
Slow, deliberate speech is easier to understand, especially for non-native speakers and in noisy cockpits.
Forgetting your callsign at the end
Always end your transmission with your callsign so ATC knows who said what.
Not listening to ATIS first
ATC will ask you to listen to ATIS and call back if you contact them without it. Save everyone time.
Saying "with you"
"With you" adds nothing. Just state your callsign and altitude on initial contact with a new frequency.
Not asking for clarification
If you did not understand, say "Say again" or "Verify." Never guess at a clearance.
Keying the mic before thinking
Know what you are going to say before pressing PTT. Think, key, speak, release.
11. How to Practice Radio Communications
Listen to LiveATC.net
Choose your local airport and listen to Ground, Tower, and Approach. Follow along with real traffic. You will absorb the rhythm and pacing naturally.
Use the Rotate ATC Practice Simulator
Our interactive simulator presents realistic ATC scenarios — taxi, departure, approach, emergencies — and lets you practice responses. Great for pre-solo prep.
Practice with a study partner
One person reads ATC prompts, the other responds as the pilot. Switch roles. This builds confidence faster than solo study.
Chair-fly your route
Before a cross-country, mentally walk through every frequency change, every call you will make, from startup to shutdown. Write it on your kneeboard.
Record yourself
Use your phone to record practice calls. Play them back — you will catch filler words, rushed pacing, and missing callsigns.
Study the AIM Chapter 4
The Aeronautical Information Manual Chapter 4 (Air Traffic Control) is the definitive reference. It is dry but comprehensive. Focus on sections 4-2 (radio comms) and 4-3 (airport ops).
Ready to practice? Our ATC Practice Simulator has 30+ scenarios across 6 categories — from basic ground ops to IFR approaches and emergencies.

Frequently Asked Questions
What frequency do you use to talk to ATC?
It depends on the facility. Tower frequencies are typically 118.0-135.975 MHz. Ground control is usually 121.6-121.9 MHz. Approach/Departure frequencies vary by region and are published on charts. The universal emergency frequency is 121.5 MHz. Check your sectional chart or Airport/Facility Directory (AFD) for specific frequencies.
What do pilots say when they first contact ATC?
Pilots follow the WHO-WHO-WHERE-WHAT format. For example: "Springfield Tower, Cessna 9-3-4-Alpha-Bravo, 10 miles south at 3,500, inbound for landing with information Delta." You state who you are calling, your callsign, your position, and what you want.
What does 'Roger' mean in aviation?
'Roger' means 'I have received and understood your last transmission.' It does NOT mean 'yes' or indicate agreement. To confirm a clearance, say 'Wilco' (will comply). Never use 'Roger' as a readback for a clearance — ATC needs to hear the actual instruction read back.
When should a pilot declare an emergency?
Declare an emergency any time you are in doubt about the safety of the flight. Use 'Mayday, Mayday, Mayday' for life-threatening distress, or 'Pan-Pan, Pan-Pan, Pan-Pan' for urgent situations that are not immediately life-threatening. Squawk 7700 on your transponder. There is no penalty for declaring — your safety is the priority.
What is the difference between Mayday and Pan-Pan?
'Mayday' indicates a distress condition where the aircraft or persons on board are in grave and imminent danger. 'Pan-Pan' indicates an urgency condition where safety is a concern but there is no immediate danger to life. Examples: engine failure over terrain = Mayday; alternator failure with battery life remaining = Pan-Pan.
How do I listen to and copy ATIS?
Tune the ATIS frequency (published on charts) before contacting ATC. Write down: the information letter (Alpha, Bravo, etc.), wind direction and speed, visibility, ceiling, temperature/dewpoint, altimeter setting, and active runway. When you contact ATC, report the information letter so they know you have the current weather.
Do I need to talk on the radio at uncontrolled airports?
While not legally required at all uncontrolled airports, it is strongly recommended and considered standard practice. Self-announce your position and intentions on the CTAF (Common Traffic Advisory Frequency). The FAA recommends broadcasts at 10 miles out, entering the pattern, each leg of the pattern, and departing the pattern.
How can I practice radio communications before flying?
Listen to live ATC feeds online (LiveATC.net) to learn pacing and phraseology. Use interactive ATC practice simulators like the one on Rotate to practice with realistic scenarios. Study the Aeronautical Information Manual (AIM) Chapter 4. Practice with a fellow student pilot, taking turns as pilot and controller.
