Thank you for the flaps info. As for the Blue note I think it needs to be faster than the flaps down would possibly allow.

Well you can go up to 300 knots or 0.9M with flaps up to 38 degrees and I think our setting in the Aeros Team was 20 degrees...The Mach Number is the more relevant at high altitude as some people have been caught out by diving with some flap at high altitude and losing control with the nose down trim. One chap got supersonic with a bit of flap and could not get any recovery with full stick and ejected at about Mach 1.0...He survived with some leg flailing damage and a badly torn mouth. It was reckoned that he had forgotten he had a bit of flap down, but I'm not sure that they ever established that.

Actually I only associate the term "Blue Note" with the sound on the ground of a Meteor doing over 500 knots and a similar noise on the ground below a Venom, totally out of control, diving vertically at full power and terminal velocity of 0.91M. The sound of both these things is surprisingly similar. I have not heard the term "Blue Note" applied to the Hunter...However, in that video there was at least one place where it was emitting some sort of a note

For a short while at Llanbedr we had an ETPS F6 on loan for Jindivik shepherding when they wanted to take away the Hawks & our Ch pilot would regularly beat up the airfield getting the Blue note! I think it must have been a combination of a certain speed & RPM & probably emanated from the intake area.
The Hunter was not a very good aircraft for shepherding, & we did of course eventually get QinetiQ AlphaJets in lieu of the Hawks.
Thanks for the data on flaps - interesting.

Edit. Just found this video - the sound I normally associate is the pass at 1:28

A hunter? And I thought it was Supercar that caused it!
