Engine failure below Vmcg
FAR 25.149(e) specifies in some detail (e.g. maximum 30 ft lateral deviation) the controllability in the effect of an engine failure at or above Vmcg.
What certification "promises" are made regarding control in the event of an engine failure on the ground (just) below Vmcg? For example, is there a requirement that nosewheel steering is sufficient to maintain the centreline? ... at least keep me the right way up?
What differences for a subpart 23 aircraft?
