This way data input can be checked by an airport administrator as being consistent for plane and admin before pilots board.
Sorry Nicolaus, but I have to disagree on that.
Far too much administration already, far too many signatures before we can go.
I believe the key is in some other place :
Probably 90% of the operation nowadays is done for a crew of only two members. These two guys must always check each other, and never ever take for granted anything. To look over your partner's shoulder is one of the main part of your job.
You have to pick up any of its possible mistakes as much as you need him to do exactly the same for you, and you never miss thanking him anytime he does so.
If one the crew made a mistake in the numbers, that's ok.
But if the other crew didn't pick up the mistake because he relied on his partner and didn't take the time or didn't have the energy to check by himself the entries ... that's where is the bobo !
Also the job is exhausting at times ... Fatigue is a major intruder ...
15 days off a month should be the rule ... everywhere !
