On Frequency
Talking on the radio is the scariest part of a first flight, and the part that improves most with practice. This page covers the basics of phraseology and has a radio simulator: a complete departure from Brasília (SBBR) to Guarulhos, from the gate to Control.
Before you press the button
- Listen. Wait for the frequency to be clear. Don't interrupt an exchange between the controller and another pilot.
- Think. Know what you are going to say before you transmit. Write it down if you need to.
- Speak. Who you are calling, who you are, what you want: "Brasília Ground, GOL ONE FOUR ONE NINE, ready for taxi."
- Read back. Repeat the instructions you received and end with your callsign.
The simulator
Choose a mode and advance message by message:
- Follow along: messages appear one by one, as if you were listening to the frequency.
- Practise as pilot: the pilot's lines are hidden. Say out loud what you would transmit, then check.
- Practise as controller: the same, with the ATC lines.
The complete flight
The communication example in the Phraseology Manual follows the same flight to the gate at Guarulhos, in Portuguese, English and Spanish, with notes on the most common variations.
What to always read back
A readback is repeating the instruction so the controller can confirm you understood. Always read back:
- route, departure and arrival clearances;
- levels, altitudes, headings and speeds;
- runways: enter, line up, take off, land, cross, hold short;
- squawk code and frequencies;
- altimeter setting.
Always end with your callsign. If the controller says "read back correct", carry on; if they correct you, read back again.

Numbers and letters
On the radio, every number is said digit by digit: GOL ONE FOUR ONE NINE, flight level THREE FOUR ZERO. NINE is often pronounced NINER. The decimal point in a frequency is DECIMAL. Letters use the phonetic alphabet: A is ALFA, B is BRAVO, C is CHARLIE. In Portuguese, some digits change: 1 is UNO and 6 is MEIA.
It's OK to make mistakes
Every controller has heard a nervous first flight. If you freeze, take a breath and say "say again". If you can't do what was asked, say "unable". Nobody expects perfection; they expect safety and clarity.
