Controls that are allowed to be adjusted by an aircraft radio operator

• A. Channel selector switch, volume control, and on/off switch
• B. Antenna tilt
• C. Frequency drift
• D. Microphone gain

Answer: (A)

The main point is that an aircraft radio operator is allowed to use only the basic, routine controls needed to operate the radio during flight. Selecting the channel, adjusting the audio level, and turning the unit on or off are the everyday, user-facing controls that keep communication moving without altering the radio’s internal settings or its antenna system. Choosing the channel, setting the volume, and powering the radio are the simple actions you perform to communicate clearly and stay in touch. Antenna tilt is a mechanical adjustment tied to the installation and alignment of the antenna, something normally handled during maintenance rather than by an operator in flight. Frequency drift involves changing or calibrating the transmitter/receiver’s frequency stability, which is a calibration/maintenance task. Microphone gain pertains to the input level of the mic and, depending on the system, is not considered an operator-adjustable control in routine operation.
