I know very little about flying 757's, or the use of reverse in a jet. However, my question is: If there were a mechanical failure of the left engine reversing system, would it not be appropriate to at least get the right engine developing some reverse thrust right away, to the extent that the directional control could be maintained with rudder, and steering if effective? Some reverse thrust, even assymetric, would be better than none?
I have first hand experience with the use of reverse on one engine only, on a PT6 powered twin, and was quite impressed as to how much decelleration could be safely achived that way. Would the same apply for the 757?
