SilsoeSid, from the GPAO accident report page 75 reads as follows:
"The operator instructs pilots that, if time is available after an autorotation has been entered and the Nr is stable, the shed bus switch should be selected to emerg, to provide power to the steerable landing light and the RADALT, a MAYDAY call should be made and, then, the engines shutdown. The operator recognises that it can be difficult to locate the shed bus switch in an emergency.
Without the RADALT, the pilot did not have accurate height information. Also, he did not have the benefit of a steerable landing light to improve the visual cues. While it was not possible to determine how much this adversely affected his ability to carry out an autorotation and a successful flare recovery, it was apparent that the situation involved attempting a forced landing at night, in a built-up area of Glasgow city centre."
SID - Are you the AAIB are incorrect?
The rest of you post I agree with except the relight reference was in respect to the first engine failing offering a possible explanation why one of the prime pumps was selected ON.I certainly agree with you that attempting a relight in auto below 2,000 feet minimum, is a futile effort.
