Flyaway manoeuvre
Any suggestions from the knowledgeable out there as to the differences in suggested flyaway (engine fail in the hover - transition to achieve safe single engine speed) manoeuvres between aircraft?
The Lynx procedure is to select 15 degrees nose down, the 139 is to adjust the attitude 20 degrees from the hover (giving 10-15 degrees nose down) and the S92 is 20 degrees nose down.
Meanwhile the venerable Sea King is generally no more than 5 degrees nose down.
Now it maybe because we (on the SK) are concerned with minimum height loss whereas the industry standard wants the quickest time from failure to SSE accepting the large height loss involved with such large nose-down selections.
Disc loading on the 3 above mentioned helos is much higher than the SK and they also all have cambered blades, unlike the SK which is a symmetrical aerofoil. I don't know if either of these are relevant factors.
Would an S92 or 139 pilot really select 20 degrees nose-down from a night, overwater hover or would the flyaway be modified for winching scenarios?
Answers, suggestions (and if necessary some crab banter) gratefully accepted.
