2.4 Transceivers

2.4.2 Describe the purpose, correct manipulation and adjustment of the controls of commonly used aeronautical transceivers.

An aeronautical transceiver is a radio unit that can both transmit and receive radio signals.

In aviation, the transceiver is used to communicate with:

• Air Traffic Control
• Flight Information Service
• Aerodrome traffic
• Other aircraft
• Ground stations

Clear radio communication is essential for safe and efficient aircraft operation. It allows pilots to obtain clearances, receive traffic information, make position reports, and coordinate with other aircraft.

Most aircraft VHF radios have similar basic controls, although the exact layout may vary between aircraft and radio types.

Frequency Selection

The pilot must select the correct radio frequency for the station or service being used.

This may be done by:

• Rotating frequency selector knobs
• Using push buttons
• Using a digital tuning interface
