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.
