Performance after failure of engine on takeoff, and SE procedures (was SE T/O Perf)

[Mark Hislop]

Hugh:

The 300 FPM SE climb rate is achieved at Vyse, and more importantly, with a "clean" airframe. With the gear down, you loose at least 100 FPM. If the gear doors are in transit, or stuck open, you will do well to maintain altitude. And if you inadvertantly take off with the rear engine not running, and therefor do not have the prop feathered, the increased drag from the windmilling prop will most definitely cause you to loose climb permormance.

By the way, except for the drag of the gear doors, all of these factors are the same for other light twins. Of course with the other twins, you also have the problem of assymetrical thrust to contend with as well.
