Engine Failure below Vmcg.

In a previous life we used to operate B757-200s into Skiathos, 5317ft long 30m wide, if memory serves!

A discussion arose over the pros and cons of full pwr t/o as stated in the books on rwys 6000ft and less and using derated thrust(not authorised). The concern being control below Vmcg.

The point being if you have a catostrophic failure below Vmcg the stopping before the end of the hard top is not the problem, but going off the side is.

So in various sim run throughs the big thing was to get rid of the assymetrical thrust asap, not worry about reverse thrust(for obvious reasons) and concentrate on brakes and nosewheel steering.

To stay on the runway rapid and aggressive inputs were the order of the day, not ideal but workable.

In the end the argument about "bad rated pwr" over "good derated pwr" was never really settled conclusively, but the results by the guys authorised to fly into Skiathos did surprise the sim guys as not one went anywhere near the edge even in the most critical scenario.

Suffice to say the books never changed and the next season we stopped going there!

Phew!
