I am referring to the phase of flight from application of takeoff thrust until gear retraction, not until 10000’. Some airlines call this the “no contact period”.
“I don't think he was saying that he didn't care about a cabin fire.”
Correct, of course it would be great to have an ECAM master warning for cabin fire that is instant and unambiguous, it’s a no brainer.
And given clear timely information about a cabin fire would certainly result in an abort.
But is a cabin crew member going to assess a situation accurately, have the clear thinking required to grab the handset, call the cockpit, wait for an answer and clearly and calmly convey the message to the flight crew all within the time it takes to accelerate from 100 knots to V1?
