Towbars are matched to aircraft so that if you turn them too far the shear pins in the towbar will break, and you won`t damage the nose gear of the aircraft. The attachment between tug and towbar is nearly universal. A pin on the tug goes through a ring on the towbar. Bigger pins for bigger aircraft...Jump to post
I've seen that the FA has to turn off some RED light, indicating to the ground personnel that the door is safe to open without popping his eye out due to pressure. That’s about disarming the door, so ground personnel can open it without the slide activating. The RED light that you can see through t...Jump to post
There was an old option on the 767 to be able to do a CAT 3A Autoland with an engine out. I assume the 757 had the same option. Baseline on the 757/767 was to not be able to Autoland with an engine out. Curious on the engine out autoland option. Was there additional equipment necessary or was this ...Jump to post
Actually, the main reason is in case you have an Engine Fire on or just after shutdown. The APU then offers you a bleed source to windmill the Engine to help extinguish any Fire. When I worked on the Tristar with Gulf Air we had a procedure for shutdown with an inop APU. Engines 1 and 2 were shut d...Jump to post
Health and Safety. There is a safety line painted on the apron, and all people and equipment must stand behind it until the engines are off and the anti collision beacon is off. Simple rule that saves lives. If the APU is inop, the pilot must radio to ops and the Ground Power will be connected. Ramp...Jump to post
A major hurdle to expansion at LHR is Ba/IAG. They own over half the slots, so will have to pay for most of the expansion, and will just get more competition and reduced yield in return. I believe they are happy as they are.Jump to post
When I worked for an European Major we had about 8 flights a day. There was a suggestion to go self handling above the wing, and someone did all the sums. The cost ended up about the same, but we would have all the problems of HR, holidays, sickness etc, plus if the number of flights decreased you s...Jump to post
As a licenced engineer, when I went for Aircraft type course training at the British Airways Engineering school at LHR, we had our own simulators in the school. The flight decks were complete, but no visuals or motion. You could fly them (on instruments) but definitely only autoland!!. But you could...Jump to post
I had no idea the L1011 had such a large tail plane! From vague memory, the tail plane was equipped with four hydraulic actuators in parallel, one for each hydraulic system. How did this work if you lost one or more hydraulic systems? How were the four actuators synchronised to prevent them "f...Jump to post
I flew a lot on Tristars as a passenger. Gulf Air, British Airways and Nordic East. When the crew pulled the throttles back to idle at Top of Descent, the whooshing noise in the cabin as the HP air took over used to wake me up, time to go to the loo before we land!Jump to post
Spent many hours on the jump seat behind the Captain. You can look down onto the ground from there. It is a real seat. Comfortable, bears no relation to jump seats on B737 or A320.Jump to post
I worked on the Tristar for many years. The British Airways and Gulf Air aircraft had Litton INS fitted. Mostly two INS, but some had a third INS in place of the Vertical Gyro. This Litton INS had a CDU for each pilot which looks like the one in the picture. There was also an Align Display Unit for ...Jump to post
A little off topic but the 757 was crucial in RR establishing itself as a credible OEM. Of 1,049 757s produced, 59% had RR. Still more impressive, of 56 original customers, 77% chose RR and 23% chose PW. (There was no GE option.) Four customers ordered both RR and PW. Totally agree. Although I'd al...Jump to post
Seriously. I'll never forget the time I literally walked down the stairs from a jetway onto a tarmac to board a Ryanair 737 by stairs.

The Tristar came in two standard body door versions.
6 large and 2 small doors with a limit of 365 pax. Nordic East in Sweden had 365 seats.
or 8 large doors with a limit of 399 pax. Caledonian Airways had 399 pax seats and crossed the Atlantic from LGW with full loads.
The B747-400 had optional Autostart for the main engines. This was fitted to the simulator at Boeing, and was pretty standard. One crew for an airline did their training at Boeing, and were taught Autostart.. A few weeks later they were sent to LHR to fly the second leg of the delivery flight of the...Jump to post
The DH Comet also had the main passenger entrance at the R1 door. In the days before jetways were invented it didn't really matter.Jump to post
It was the El Al B767 that had an EICAS screen, and some more buttons. Something for the 3rd pilot to do!!Jump to post
Your first two pictures show a pretty standard B767/B757 panel. Nearly all the things you can see are test switches usually used by the ground engineers. At least most of the B767 I worked on looked like that. Some also had an EICAS screen there for the ground engineer. Typical Boeing from 1980s wit...Jump to post
For some airlines, it's a security requrement if either the access to the jetbridge from the gate, or the access to the jetbridge from external stairs don't have some type of lock on the doors. If this is the case, the jetbridge must be pulled from the aircraft to prevent unauthorized access. This ...Jump to post
I looked after RON aircraft here at ARN for over 25 years. For about a year there was a security problem and we removed the jetway. But the other 24 years we left it in position. The aircraft was left in Ground Service with the door closed and sealed (just a tamper indicator) and the jetway attached...Jump to post
A mechanical interlock was retrofitted to the control stand after the Papa India crash. You could then only move the slat lever if the flap lever was at Zero.Jump to post
Electric is nothing new on the ramp. Baggage tugs have been electric here in Stockholm as long as I remember. No diesel vehicles are allowed in the baggage halls.
Nordic Aero used an electric push back tug., and an electric pallet loader on our A330 back in 2014
To go back to the first question, ingesting a flock of birds will damage the fan blades, and maybe the fan OGVs, but usually the core of the engine survives. Twice in my career have I changed fan blades and repaired OCVs and sent the aircraft away. It still amazes me how resilient engines are. I wor...Jump to post
In fact, quite a lot of work doesn’t require the A&P, just work under the guidance of one . So why exactly do I need an A&P then????? Because without an A and P your work will be limited.

Everyone is commenting on how normal the Concorde noise was inside, lets not forget it was very noisy outside. On the occasion of Gatwick airports 50 anniversary, BA substituted a Concorde on some B737 flights out of the airport.

I would like to second GDB post on the internal noise. Only flew once on Concorde, and AF one from ARN. Thge noise inside was quite acceptable and no higher than other narrow bodies of the time. Noise outside was something else! Our staff car park at LHR was at the end of 28L. When Concorde left in ...Jump to post
Modern jet airliners do not have an anti ice system on the tailplane.
Hot air deicing of the stabilisers was present on some 1960 jet aircraft, but not fitted to large jet transports today.
When I worked for TWA at ARN in 1988, you could book your seat when you booked the flight. All bookings with seat numbers made a short time (cant remember how long but about a week) in advance were sent their boarding pass through the post.

When I went to work in Bahrain in 1976, Bahrain was by far the most important airport in the area. DOH AUH DXB and MCT were all much smaller.

Jay, there’s no metric on airliners. You may have missed the jokes. No mechanic anywhere working on airliners has metric tools anywhere.

Of course BA has more flights but for not a single other carrier to need to cancel a flight while BA cancels 66 there surely must be more than weather at play. A BA shorthaul aircraft will usually land at LHR 3 times a day. They don't go anywhere else so they have to wait for slots there. A KLM sho...Jump to post
Continental and United are based in the USA and follow FAA rules. They have an 8 hour rule.
SAS is based in Europe and follows EASA rules. They are different. There is no hard 8 hour rule.
What United does has no bearing on this thread!
My original ME instructor said to start the one closest to the battery. :smile: Starting up a Tristar in the Middle East could be the same. The Tristar APU had very poor air delivery when it was hot outside. We normally started Nbr 3 first, then closed the isolation valve to get Nbr 3 pack on line....Jump to post
So when they tow a plane, no one is on board? There is supposed to be someone "riding the brakes" who usually boards from the bridge and closes the door. When a TBL is used for towing, the aircraft should be empty. It is dangerous to have a brake man as putting the brakes on will damage t...Jump to post
There is a “flight idle” setting, that is higher than the “ground isle” setting in order to provide faster response in the air. Modern big jet engines now have an approach idle. The engine stays at ground idle until it is close to landing, then accelerates to approach idle. Approach idle is designe...Jump to post
again off topic, but does anyone know why the first forward half of tristar wing engines were painted and rear not?

Question for Tristarsteve, who may know the specifics behind it. Late70’s BA lsd a L1011 from Eastern, N323EA. However, they seemed to keep it quite a while, and was never re-registered in the UK.

BA converted many of their Tristar 200 to remove the lower galley and extend the fwd freight hold in its place. The main deck galleys were made larger by removing the lifts. They must have made more money from freight than Y pax. Was this the Tristar 200F??Jump to post

What are the differences between the 100 & 200 in the family? I believe the A320-100 didn't have wing fences, whereas the A320-200 did. Not sure about the A321s.

You don't want the fan to stop turning. Spinning in the breeze is much better.
Many years ago I was doing some engineering things with a Tristar simulator, and afterwards we went flying in it, and the simulator engineer simulated a seized fan. Loads of vibration and very noisy. Not recommended!
But it isn't a full pax aircraft. It has VIP fittings including a presidential bedroom.Jump to post
I worked the Tristar/Rb211 for a long time, from 1974 to around 2000.

But after a couple of years it was redisigned and much easier, if the translating...Jump to post
As every one is guessing here BA had a number of B744 fitted with RB211-524GT engines. The HP 04 module was replaced with the 04 module for the Trent engine.
