Phraseology
How to use this page
The examples come from Section VI of MCA 100-16, dedicated to AFIS (Arts. 153 to 158)1. Pilot transmissions appear in the green bubbles on the left; those of the RADIO, in the blue bubbles on the right. The callsigns, frequencies and names are those used in the examples of the manual. Replace them with those of your position.
The RADIO callsign is the name of the location: Rádio Altamira in Portuguese, Altamira Radio in English.

What not to say
At the RADIO, control phrases become information phrases:
| Avoid (control) | Use (information) |
|---|---|
| Cleared to land runway 07. | Roger, wind calm. Report on the ground. |
| Cleared for take-off. | Roger, wind calm. Report airborne. |
| Taxi to holding point runway 05. | Roger, report holding point. |
| Hold position. | Traffic known is a Xingu on downwind leg runway 05. |
| Number two, follow the Xingu. | Traffic is the Xingu on downwind leg, ahead of you. |
| Climb and maintain FL 045. | (The RADIO does not assign levels. If there is a clearance from another unit, it is relayed: "cleared by the Center...".) |
