Bac 1-11

[maxdrypower]

Troops , Now I may be wrong on this , but I am sure there was a documentary some years ago featuring ETPS . During this documentary they showed a 1-11 doing some rather daft things . Does anyone have a link to this on T'internet if its even on here , and indeed if my memory is serving me correctly , I may have been dreaming it :ugh:

[GGR]

I remember there was a documentary series, six episodes I think, entitled Test Pilot on BBC 2 ? There was also a book released at the same time of the same name. Each week it featured two or three of the ETPS a/c types being put through their paces by the trainee Test Pilots. Hope this jogs your memory as I reckon you will be lucky to find any internet footage??

The book by Brian Johnson published by BBC books ISBN 0 563 20502 4 in 1986. Hope this helps.

Have managed to find quite a bit on you tube but none of the 1-11 . It was specifically that I was after , or any other footage of a high T tail aircraft in a deep stall

[pulse1]

I've got the series on video somewhere. The problem is that its on Betamax and I can't play it.

Pulse 1, Check your PM's.

On a slight thread drift, anyone know if the American 1-11 test bed aircraft is still with FR at Bournemouth?

[billynospares]

I believe Northrop Grummans 1-11 is still at bournemouth but could be wrong. You wont find any footage of 1-11 in a deep stall because if you do it you will die. Stick shaker and pusher wont allow it anyway including ETPS 1-11

[maxdrypower]

I thought that might be the case , but also thought it may well have been done perhaps with use if a chute or something . Not to worry . To answer New Forest , there was a 1-11 at FR yesterday White with a green symbol on the tail , not sure if its the same one

[ZeBedie]

BAe had a 200 series with a tail chute which was still being used as a comms aircraft in the 80's and still carrying the mod.

[billynospares]

xx105 did it with a tail chute but also crashed whilst doing it on salisbury plane. was recovered and repaired and flew up till a few years ago. it is now part of the boscombe down aviation collection

[Newforest2]

Billy,

The test plane is N162W and it didn't look green in the last photo I saw in 2007 but then how many 1-11's would be at Hurn now?

If you saw the nose, it should look like Pinochio.

I suspect it might be involved in the new refuelling contract for the US.

Whilst on the ground at Old Sarum yesterday, I saw the ETPS Bae 1-11 doing circuits at Boscombe Down, so it's still active!!

[ICT_SLB]

The original RAE 1-11s were 400 & 200 series IIRC - I worked on both the Avionics test one (Type AK/D?) and the BLEU one (an ex-BUA Type AC which, perversly, was rumoured to fly 3 degrees off unles it was rigged offset - the product of a heavy landing). The current EPTS one is a 500 series I beleive and it's still active - the last item in "Flight" was as a stand-in UAV. There is a 1-11 group on yahoo that sometimes has almost minute by minute updates on movements in & around Hurn.

Rumors on this side of the pond is that the N-G fleet will be replaced soon by other T-tailed aircraft with CF34 engines.

[billynospares]

ETPS fly a 475 FU variant ZE432 also there is ZH763 a 539 GL and ze433 another 475 FU all still in service as test beds

and scroll down to the comments that people make.

There's a guy there with the whole series on DVD and apparently he can arrange a copy for you.

I have had the pleasure of being in the one of the RAFO 1-11's here in Oman.....so beautiful and imaculately maintained flightdeck!

"BAe had a 200 series with a tail chute which was still being used as a comms aircraft in the 80's and still carrying the mod."

ZeBedie,
Think You must be thinking of G-ASYD which was the prototype 400series etc.. and is now at Brooklands Museum. We have the Anti-stall / Anti-spin rig and parachute but cannot refit due to missing fittings sadly.

It's actually N164W and it departed Hurn on the 29/3 for Keflavik and presumably back to The States.

The 1-11 currently at Hurn is the Omani one (553). The flag on the tail does have a bit of green on it but is more red!

[Newforest2]

Thanks for the correction LT! Interesting that Grumman have three 1-11 test beds, N162W (087), N164W (090) and N161NG (067).

[ICT_SLB]

NF2,
The 3 1-11s are used by Northrop-Grumman (N-G) as radar test beds - rumor is that, owing to fuel costs & noise, they will be replaced soon.

[ZeBedie]

ZeBedie,
Think You must be thinking of G-ASYD

Yes, when I last saw it, at Warton, it was white with red stripes. I think the rear airstairs were permanently disabled because of the mod. But it was still carrying pax.

[Pugilistic Animus]

I'd love to hear an account by someones whose done deep stall testing;)

I heard from a friend that it's then scariest maneuver ever:eek:

please tell us!:D

[rhino11]

I was sat at Lyneham today with my camera when this appeared in the circuit. I hope it is of interest.

In the last few weeks we have also had the other two Boscombe Down based machines through.

Not 1-11 but a related question occurred to me lately, a friend was involved in the stall tests on the Trident; he was a chum of George Errington's, and we know that sad story...

My chum described taking the Trident to within 1 degree of the Alpha limits, he reckoned it had 'very precise handling' - when I asked if he had a specially calibrated guage he looked blank & shook his head !

I have my own guesses as to whether this was wise, but does it even sound feasible to you Test Pilots out there ?

[FlightTester]

I have my own guesses as to whether this was wise, but does it even sound feasible to you Test Pilots out there ?

I guess it depends on which alpha limit he went to - the AFM limit or the Flight Test Envelope limit. I don't know whether the Trident stall was pusher defined or not, some T-tails need a pusher defined stall (Challenger, CRJ), some don't (Learjet 40/45).

If the Trident was pusher defined and he went beyond pusher alpha by disabling the pusher - then definitely not the smartest trick in the book without an accurate gauge or FTI. The risk of deep stall being all too real at that point. If like the LJ the stall is defined as "two seconds on the aft stop", then going to within one degree would be less of a risk although still not smart without a very good reason to go there.

In "Test Pilot" by Brian Johnson there is a chapter on BAC 1-11 stalling pages 88 to 91,using ETPS ZE432.
