920.1.8 FLIGHT OPERATION IN MODE A/C/S (REPLY CODE AND ALTITUDE CODE)

1 When ATC requests the transmission „squawk", switch the transponder to ALT using mode
switch (A).
In exceptions the altitude has to be turned off, i.e. switch the transponder to ON using
mode switch (A).
2 The transponder replies using the selected Code and in response to mode C interrogation it
transmits the altitude of the aircraft to ATC. A 'R' on the left next to the Code on the display signals
the transponder replies.
Switch the transponder to Stand-by (SBY), if the Code has to be changed. Otherwise if
could happen that a Code with a special meaning (see chapter K, e.g. highjack) will be
transmitted and unwanted actions could take place.
