Thanks Sycamore.
The thumb wheels you refer to. Are they on the AFCS panel and are the nulls checked on the cross wire circular dial adjacent to it?
Recall the term vent run. Is this an engine run which turns the compressor stages with the fuel system/ignition inactive ? Would this be achieved via normal engine start buttons on SSL but with ignition and computer switches off and start delete on, plus of course fuel firewall valve off
It's interesting to read through the aircrew manual for the H-3 which doesn't seem to have ignition, computer or flight idle switches but does have emergency start controls. Does the Westland Sea King have emergency start ?
