Andre Turcat
ChristiaanJ,
not really. I believe he was a guest at the first IFALPA Conference I attended which was organised at very short notice by SNPL aboard a ship (the Mermoz") but I was way junior too on the BALPA team to get to talk to someone like that. Brian Trubshaw's mother lived half a mile from me when I was a kid in South Wales though! |
links for the Museum
email link is on the link below. British Airways - Heritage collection - web address through BA page. One of their staff of volunteers was present at the first ever departure from LHR. |
Thanks!
Link didn't work, but for anybody interested,this one should. BA museum collection CJ Edit, no, it doesn't work either, if you use an ad-blocker. Copy and paste the URL: "http://www.britishairways.com/travel/museum-collection/public/en_gb" |
Can you advise where the Trident cockpit is located, I seem to remember it was supposed to be located near a public house near the south side of Farnborough airport..?
Thanks |
typically it was the OCCUPANTS of a Trident cockpit who were to be found near pubs in the vicinity of airports.......

Trident 3
For all you Trident fans, while clearing out my office I rediscovered an interesting article in an old Flight magazine. In the April 8 1971 issue there is quite a long article about bringing the Trident 3B into service and also one about how they are built. I have checked and the edition is available on Flight's archive.

ITman,
I think the one you're thinking of is G-AVFH HS121 Trident 2E - Forward Fuselage at the de Havilland Aircraft Heritage Centre. |
Don't know if this will work here but I'll try it:-
http://www.petermcleland.com/misc/TridentCockpit.gif It is a comparison of the real thing and David Maltby's Flight Sim model. |
Peter,
That's great. You really have to look closely for the differences (apart from the missing PVDs in the original pics, of course). CJ |
I'm missing something here - who is David Maltby and what/where is the model? Both pics look pretty real to me!

The original PVDs are there if you look closely...The black rubber surrounds on the real thing used to sag quite a lot and the slot through which to view the "Barber's Pole" closed up a bit. However, when you sat in the seat the scrolling of the pole to left or right was clearly visible. |
Slast the model is the one built for Microsoft's Flight Simulator by David Maltby. It is an extremely accurate simulation which will even do an autoland with full "Kick off Drift" in Fog. The other picture is the real thing. Both are the Trident 3 with boost engine.
Here is a YouTube video I made of a turnround using this model:- YouTube - TridentTurnround.mp4 It has sound. |
Thank you chaps for the fascinating insights. Very interesting and enjoyable.

I always thought the PVD was an interesting idea at the time, much like the 'tunnel' displays, and the HUD, and MicroVision, none of which really were adopted in the end. (The 737NG does seem to have a HUD as standard, but I don't know how much it's used. We had a very simply HUD for runway guidance on some of the early Airbuses, but that too 'didn't make it'). CJ |

So I have to ask, how does the virtual Gripper compare As an aside, his BAC 1-11 and VC10 aircraft are equally as amazing. The man deserves the PC equivalent of an Oscar!!! :ok: Tom |
T3 and Boost Engine
Mention of the introduction of the T3 sparks memories. The fact that the engine was ‘plastic’ gave rise to great incredulity. The first few months in service however, saw a concrete block because it had not yet proved itself. When in service, it required (IIRC) a min of 900 kgs of fuel in the centre tank. The engine was shut down on reaching 3,000ft, by pressing the fail light, often by P2’s left foot! P3 was always kept busy when taxying out at LHR because any intersection T/O would require a YES/NO or a revision of figures. When in the R/H seat, I had a flight to ZRH with a particularly fuel conscious management pilot (TW). On arrival, he asked for our estimated T/O weight and this required the boost engine, so the extra 900 kgs were duly loaded. When the papers came, we were 5 or 600 kgs over the ‘No Boost Wt’. This, of course, was caused by the extra 900 kgs. Much cursing and grumbling ensued, all the way back home and his calculator was read hot working out just how much that had cost the company (and, of course, it was all our fault).

Historical note...
PVD's were used (to the best of my knowledge) on only one civil American type, a Gulfstream One aircraft, owned and flown at the time by the radio and television personality...Arthur Godfrey. With this aircraft, CATIIIA hand flown approaches were FAA approved, circa 1960. The PVD's were certified and provided by the Collins Radio Corporation. Having used the PVD in TriStar equipment (ex-BA aircraft)...they worked to perfection. Full marks for the designers of the HS.121 Trident aircraft...they provided CATIII autoland when others couldn't/would't/didn't. A superb achievement. |
Some of the 744s I used to fly had PVDs. Airbus has a PVI (for indicator) as an option.

Thanks for the information ChristiannJ and Petermcleland I have now found the Farnbourough location:
The nose section of Trident three G-AWZI is located at the Farnborough Air Sciences Trust (FAST) museum, Farnborough airport. The museum is open every weekend and bank holidays from 10:00 – 16:00 and entrance is FREE. Address: Farnborough Air Sciences Trust Museum 85 Farnborough Road Farnborough Hampshire GU14 6TF Telephone: 01252-375050 Website: Farnborough Airsciences Trust homepage. It is worth a look at their website many interesting items there.... |
Prober - re the boost fuel - I stand to be corrected, but IIRC the fuel load was calculated in the normal way and 900KG min (ie it wasn't an extra 900kg) was loaded in the centre tank as that was the only tank that fed the boost (or an imbalance would result if it was fed from a wing tank). What was left was used in the passing FL100 fuel balancing process.
The T2 had a fin tank (700kg??) which drained into the centre tank - there was a speed limit (300kts??) until it had been used - also the T2 had water injection as an option on take off. This enhanced performance as long as you didn't want to climb, accelerate and turn at the same time. I remember a few occasions at Naples climbing into an inversion, turning and automatically levelling out. The original Trident had 'pitch pvds' to the outboard of P1 & P2. David Maltby's sim looks very close to the real thing - with the significant ommission of the pen holders under the coaming and chart holders below the DV window - both vital + (the scrap of card on the coaming with the flight number on it!) |
Trident 3 Sim
A few years ago a 'flew' Andy Mattick's Trident 3 sim; He had a purpose-built barn for the beast, and I remember doing night touch & go's at Gatwick (no day visuals were available).
As I recall, you did not attempt to flare for landing (this inevitably resulted in a stall), but flew the aircraft straight onto the deck. The sim was somewhere near Tatsfield- lost his number, so I don't know whether it's still operational. |

BTW...as someone mentioned, I had a very small part in its development but only very tiny points about things like the drift shutter operation and how the handbrake two sets of gauges worked etc. He did all the modelling and programmed the flight characteristics which are extremely realistic compared to the real thing. I wrote the Autoland Tutorial that can be downloaded with it and supplied some files that set up various training flights from Heathrow, culminating in a full Cat IIIb approach with very near minimum conditions. The other really amazing thing about it is the fact that it is Free! You can probably judge just how realistic the Cat III is by glancing at these screenshots:- FSScreenshots.com Forum - Viewing topic #5514 - Anyone for CAT III... |
Hi, very interesting thread.
There used to be a guy named Andy Matocks who had a fully functionaling ex BA Trident 3 set up at his farm. It used to be about 100 quid for 2 hours. The sim was located near to Biggin Hill airport. I'm afraid I don't have any contact information now, but a bit of 'googling' around or a trip to Biggin Hill would probably find Andy and his sim. rgds Bob. ps I seem to remember reading somewhere that information regarding the Papa India accident in 1972 was classified for 50 years. I've read the accident report, but I'm curious about what mustn't be released for 50 years. Anyone got any ideas? Cheers. |
Found this going through some old pics. Shame I can't get the scan clearer!

Thank you all for bringing back long forgotten memories of the Trident Auto Pilot system I was a avionic mech who helped to de-snag all the defects in the central area at LHR crawling under the flt deck floor to the "Electrics bay"to change the triplex system of pitch,roll,yaw , and autothrottle computers which were situated there plus that blasted signal generator that was housed there as well without which we would never have be able fault find and recertify the Autoland . it had its faults as a system ie it had mechanical switching as electronic switching was not available at the time and these used to stick and that channel was "thrown off " by the the other channels ,but from the late 60s to the end of the Tridents life it did 1000s of Autolands safely and may be did not repay the huge amount of the costs of development but it cut down huge diversion costs in bad weather But it was the first and the A.R.B. laid down very hard demands to reach its goals
it could all be summed up by the remarks the passengers said which were "Did WE Land in this fog, how are we going to drive home ?":ok::ok::ok: |
Does anyone else remember the trouble one had starting the T3 boost? I seem to remember having to open the rpm on number 2 at a very carefully judged rate to get the damned thing to light-up. Too fast on the rpm increase and it would stall; too slow and it would overtemp, resulting in flames gushing out of the tail-pipe.
There were Boost-Engine-Gurus, who could always start the blasted thing first time. And when you switched the thing off (at 9,500 feet?), the average disgusting Gripper Mark 3 would start to descend! The T3 was absolutely and indisputably the second-worst aircraft I've flown. The worst was the Piper Tomahawk, but the revolting T3 wasn't far behind. The T1 was a nice aeroplane; the T2 was a sports version. The Trident 1E was the turbocharged edition. I'm sorry for the poor souls of my generation who were condemned to a decade flying the Trident 3. They deserve a medal. :) AD |

Unfortunately the Trident never operated out of Gatwick. Although as far as I’m aware there was never a permanent Trident base at LGW, it was not unknown for an aircraft and crew to be based temporarily at LGW, to cover aircraft shortages or unserviceability there. Twice in the 1980's I did just that, being based at a LGW hotel for a week, and operating to FRA and DUS. Regards Trident Sim |
Indeed, I should have been more precise, and have said that there was not a Trident base or schedule at Gatwick.
I think the only London bases were Heathrow ....... and Stansted (that should be good for a few more posts :) ). |
I'll talk to tristar 500 and ask him to give you the gen, he used to be good at starting boost engines at 4am in the morning on ramp checks.:ugh::ugh:

I've just been reminded of a Video that an ex BA crew friend made of the Trident Autoland in Flight Sim...It makes some use of the "Virtual Cockpit" as well as the 2D Panel. It runs for about 4 minutes and is best viewed when clicked up to HD 1080 and "Big Screen". It has sound:-

Just why was the Trident a three pilot flight deck when surely most short haul aircraft of the era had become two crew operations?

Sorry, yes I forgot the 1-11, that was first delivered in January '65 so didn't pre-date the Gripper. The other shorthaul jets of the era included the Comet and Caravelle which were both 3-crew.

As avionic type haas quoted me as a Boost engine wizz!! I should point out that the biggest problem we had with them was lack of use, resulting in the fuel draining back to the centre fuel tank. This required the fuel system to be bled, my dodge was to bleed it but instead of doing a blow out to clear the residual fuel out of the system, was to replace the fuse & go straight for a start & most times that would fix the problem. I do recall that the run procedure was via the control switch on the overhead panel which could be selected to the rpm required, "eg" idle, climb & take off.
Wookey has commented on the crewing for the Trident. It was a very complicated aircraft & very advanced for it`s time. However in BEA (Best Ever Airline) we flew with a third pilot, other airlines like Northeast used a Flight Engineer. Their main task was monitering the systems as any failure had to be dealt with manually, "eg" generator or hydrualic failure. |
I always thought that BEA was Back Every Afternoon.
