If the left transponder is set as the primary transponder, then the normal source of air data is from the left AIMS cabinet. If that data input is lost, the transponder does NOT switch automatically to the alternate source in the right AIMS cabinet, it requires the crew to manually switch via the ALT SOURCE switch on the transponder panel.
If an oxygen bottle has ruptured in flight destroying the P105 left wire integration panel/left ARINC 429 bus/left AIMS, then considering all the overwhelming failures associated (electrical, flight controls, pressurisation, navigation, communications, displays, etc), switching transponder or air data sources would not be the first priority.
Startle effect, cognitive overload and cognitive tunnelling would be highly likely following an oxygen bottle rupture inflight. Items will be missed.
Has anybody any of you Wonderful aviation gentleman gone back and had a close look at the Egypt air fire on the ground at Cairo an Oxygen fire in the cockpit burnt through the side of the cockpit and also destroyed or damaged The catering area ( for want of a better word) the fire of course was feeling on the air around the aircraft but what if it happened with the aircraft was in flight and pressurised??
Quite likely the crew would have to vacate the flight deck.
What are your thoughts on this?
