If I'm 180-minute EDTO approved, and I have an engine failure right at the ETP, which is exactly 180 minutes from my selected alternates, am I actually required to fly the company’s OEI diversion speed (say .85/340) to remain within the approved 180-minute limit?
The reason I ask is that our operations manual specifically states that the OEI diversion speed is used both to define the area of operation (i.e. max diversion distance) and for “conducting the diversion following an engine failure.”
