DISPLAY
The display shows the operating mode of the transponder, the
reported pressure altitude, and the current squawk code. The
reply indicator is active when the transponder replies to
interrogations and the IDENT indicator is active when the bezel
IDENT button is pressed.
The reported altitude is displayed as a Flight Level, which is the
pressure altitude in hundreds of feet. When non-standard
atmospheric conditions apply, this may not match the altimeter
indicated altitude, but will be correctly displayed by the ATC
radar.
