Return to reciprocal runway advised in emergency ?
As a previous post mentioned, glider pilots do train for power failure on launch, in the preflight check mnemonic a last item `E `for Eventualities is included i.e. what do we do in the event, I am a gliding inst and tug pilot and as a tuggy I also add eventualities to my pre takeoff checks.
I think a little pre-planning might save you one day. worth a thought?
