Engine Out Speed vs Holding Speed
Question is specific to 767, but I imagine it is the same in any airliner.
What do each of the above speeds represent?
I have been told by different people that each is the minimum drag speed, so which one is it?
I would have thought the engine out speed was minimum drag (to minimise altitude loss after engine failure). In which case why is the holding speed less than the min drag speed? If this is the case and you were required to hold en-route at altitude, would you reduce below min drag speed and risk having an engine failure on the wrong side of the drag curve?
Thoughts?
