2012 GR4 Role Demo Cockpit Footage
Hi,
Not sure if this has been posted already but i thought this was an awesome high quality video filmed from the back seat of Poker 1.

Typical NAV....head spinning trying to figure out where he is.
All he had to do was ask the Pilot!

Very nice !
Spotted the second aircraft tucking in behind at just before 8.40 mins.
Probably the best use of a GoPro 2 I have ever seen.

In relation to the moving wing, does the pylon also pivot so as to maintain whatever is on them keeping parallel with the main airframe?
I saw a demo like this at Duxford last year, nice to see one from the other perspective.

The pylons rotate to stay parallel to the fuselage centreline as the wings move.
The wingsweep lever is manual. Not sure whether GR1/GR4 had it fitted, but the F3 had auto wing sweep at the factory and was taken out on delivery to the RAF. The Saudi jets had it fitted and kept it. Apparently, it was the girls at Boscombe Down that didn't like auto wing sweep as they do it much better and faster themselves - quel surprise an above-average to exceptional managing to handle it better manually! But try putting manual wingsweep at the hands of an average Joe F^cknuckle and the Nav would constantly remind tye stick-monkey to sweep the wings as they were about to be overstressed or asking for wings forward as the AOA shot through the roof and the wing started to stall!
Only 25, 35, 45, 58 and 67 degree wing was cleared for use. Although Barnes Wallace designed VG wings for tuning to the desired speed, in practicality it could never be cleared for fatigue and overstress throughout its entire envelope without being prohibitively expensive.
I hope that helps...
Cracking video though
PS. It looks like it has been speeded up to look like an F3 flying the same profile

I good example of the poor vis in the back of a fin, esp the GR with the intakes going well forward of the back seat. That guys head is well and truly above the head box of the ejection seat, not recommended!
Didn't you spot him at 20s going the other way?!
It was a lot more obvious at that point though.
At 8.40 it could have been mistaken for a reflection or a video artefact

Looks pretty high in the headbox to me and reinforced by the apparent angle of the harnesses as well as the head to canopy clearance when the chap moves his head about.
Not saying I have not done it myself from time to time...

When doing anything that requires decent lookout, who wouldn't motor the seat up as far as necessery. I don't recall ever thinking, "Those guys on PPRuNe are going to have me if they ever see me doing this!"
The teaching on the upper limit of ejection seat position is a clenched fist between helmet and canopy in the front seat, and a flat hand in the back seat. There's easily a flat hand's room in that video, and I didn't see him bang his head on the canopy once! Even with what's almost a fisheye lens it looked fine to me. Knowing the back seater, his experience and his attitude to safety, I'm sure he'll be delighted to know that the PPRuNe panel is sitting in judgement!
