Becker BXP 6401 Transponder
The Becker BXP 6401 transponder is a Mode
S transponder which enables ATC to locate,
identify and track the aircraft by responding
to ATC radar interrogations. In Mode S it will
conduct altitude reporting, used by other air-
crafts TCAS systems for collision warnings.
Remember to turn the Transponder to STD-
BY after landing when leaving the runway.
The transponder is turned on by rotating the
left knob to STDBY. In STDBY mode the tran-
sponder will be on, but it will not respond to
ATC interrogations. STDBY is normally used
until the aircraft is ready for runway line-up.
There is a short self-test on start up. Turning
the knob to ON will make the transponder
start to respond, but without altitude report-
ing. The blinking R symbol, indicating that
the unit responds. When the knob is at ei-
ther STDBY or ON the bottom line will show
the aircraft identification number.
Turning the knob to ALT will make the tran-
sponder respond with altitude reporting
when inquired. Current flight level will be
displayed. Flight level is altitude in 100th of
feet with the standard setting at 1013 mb.
(1013,2 hpa)
