TXPDR use at LHR?
Anyone from 121.9 or .7 listening?????
A recent change in procs has us selecting the txpdr 'On' before pushback (rather than lining up) to provide a secondary return to Ground movement radar.
It is implied that, while taxying, we should squawk 0000+modeC.
Is this right? Or could we select the squawk issued with IFR clnc?
And, for anyone working outside LHR: Would this procedure cause you grief, since SOPs now have us squawking on the ground at every field we fly to.
Thanks, if you can help.
PS I always thought A0000 meant "I'm not sure if my mode C is accurate"?
