This is one of those situations that justifies a wage packet in order to be laying on a beach in Barbados 2 weeks, or looking for a new job after having your face plastered on the news for f**king up !!
If V1 is taken literally and is the point where you must go as there isnt enough runway to stop, then surely you must go.
It takes 2 seconds to realise you have a problem and 1 second to decide you are going to stop in which any case is well past V1. If i had a glance and saw that engines were fine, we are going and we sort whatever problems we have in the hold.
I suppose, like anything, its easy enough to speculate until it really happens to you ???
With the Captain/FO debate, we have a different kettle of fish and thats why we have CRM. How many FOs would not say anything thinking the Captain is gonna do the same as they are thinking.
Maybe new aircraft should have a computer fitted that can detect the problem in milliseconds, as in flight, and take the correct course of action immediately. They do everything else for us so why not let them take the flack if it goes tits up
