Question

When making routine transponder code changes, pilots should avoid inadvertent selection of which code?

1) 4096
2) 7600
3) 1200

Answer 1

Pilots should avoid inadvertent selection of code 7600 when making routine transponder code changes because it is reserved for radio communication failure.

Step-by-step explanation:

When making routine transponder code changes, pilots should avoid inadvertent selection of code 7600.

This code is reserved for when the pilot is experiencing radio communication failure.

By selecting this code, the pilot alerts air traffic control that they are unable to communicate through standard radio frequencies, and ATC will take appropriate measures to ensure the safety of the aircraft.
