This commercial fascination that some airline's Flt Ops departments have with these laptops and optimized take-off performance are really kind of a sad joke.
It's picking fly **** out of pepper.
At a former carrier we had a system where we sent runway and weather info via ACARS and we got a piece of paper back with the speeds on it. We entered the speeds in to the MCDU and away we went. That carrier has been operating FBW Airbus since they entered service in about 1988 and to my knowledge there has never ever been a single entry error for take-off weight. No laptops - they are bull**** imho. Somebody elses idea of a clever way to introduce a lot of work for very little return and the potential for huge errors with potential for catastrophe.
It's a little bit like management's non-response to fatigue reports.
HOW MANY DO YOU HAVE TO HAVE BEFORE YOU SEEK A SOLUTION?
WHY DID YOU NOT SEEK CHANGE AFTER THE FIRST INCIDENT? What are you waiting for, exactly? I'd love to know. I really would.
There's much to be done, let's get at it.
