There were a few mnemonics for problem solving, I vaguely remember BANGGEARO for the Touchdown Switch. From memory it was:
Bus Not Tied
Anti-skid
Nacelle pre-heat
GTC Door
Gear Latch
Engine Anti-icing? (Eclectic Emu? - can't really recall)
ADS 'Doll's Eyes' (Hazy on this one as well but seem to recall that zebras don't fly)
Radome Summat? (Just starting to make it up now)
Omega TAS Input (was actually my department)
To be fair it was fifteen years ago, I was mostly working in the map room and I've had a few careers since then...
