Here you go Feathers, it's in French but you can see what the modification did. (Before the modification was embodied there was an RTOW limit placed on the aircraft; perhaps Brit312 can remember the figures? OH, and as to the contingency time limit (which I forgot to answer your quesy, soorry
) it was 2 1/2 minutes. (The only time that I can recall the limit being accidently exceeded we told Rolls Royce who after a few minutes of head scratching came back with a 'no problem man, don't worry about it
).
