You are right of course BEagle and I did not go into details about the poor original T1 cockpit fit for many reasons. The Dunsfold pilots were mainly concerned to get ADD and fuel flowmeters fitted as the former allows a good instructor to teach everything about flying the wing and the flowmeter how and why we deal with jet engines the way we do.
Sadly neither was in the RAF spec because the OR staff of those days, who clearly had no grasp of angle of attack, said they learnt to fly properly without it and it was just a Dunsfold/Harrier fad that had no part to play in flying training. Since it was not in the spec we were forbidden to clutter up the cockpit with such stuff even if it was free.
