I am probably about to upset the theoriticians, mathematicians, Monday morning quarterbacks and promising hysterics among you.

Let me first of all tell you that I have been operating Perf A aircraft (mostly 4-engined) since 1962.

I have to tell you that some aircraft are great "stoppers" and others are great "goers".

For example, the DC-10 is a great "goer" and a lousy "stopper". Therefore, an engine failure 10 knots before V1 at St Maarten heading for JFK at MTOW with a tailwind (better solution than heading for the mountain) definitely makes the "going" option much more attractive.

On the other hand, the Short Belfast was a lousy "goer" but an absolutely brilliant "stopper". So an engine failure at MTOW at V1 at Gan would mean a fistful of meaningful reverse thrust and an early return to the bar with the brakes hardly warm!

Both aircraft conformed to Perf A but common sense dictated that they be treated entirely differently.
