You could do that on a Gazelle but the Wessex, Lynx and Sea King all required some head movement to scan the instruments, especially if you were on standbys.
Really? The basic T is essentially the same in all of them and eye movement did it for me, although I didn't experience the Lynx. Even my later life with graduated lenses didn't require any head movement for analogue instrument scan in many different civilian types. The standby AH in the Sea King is almost touching the main AH, and when on the HAS1 I 'pioneered' the adjusting of the engine instruments so that when in normal operating range the needles were all vertical and easily checked. Anyway, that's what the left hand seat is for, isn't it?
We'll have to agree to disagree.
But we do agree that the AH is a primary instrument for IFR
