A question for T7 drivers or engineers
There has been some speculation regarding a fire or an oxygen bottle explosion in the forward avionics bay.
Based on knowledge of what systems are there, if such an event had occurred, would it be possible for the crew NOT to receive a cabin altitude warning or indication, should a depressurization have occurred?
This could possibly lead to the crew becoming incapacitated, with them attempting to return to KL, becoming disoriented and then losing conscious.
