Due to higher drag from having to fly at lower altirudes with three engines, they had to land at MAN. That is not true. Go read the report. Over the UK they had sufficient fuel to go and land at LHR, but the fuel was not in the right tanks. The B744 has a complex manually controlled fuel system, an...Jump to post
I doubt they just laid the fan in first class. For an engine out ferry flight, that is normal. Lay one fan blade on each seat, and tie it down with a seat belt. Fan blades are very fragile. There are special shipping containers for them, but not in PHX. Wrapping them up for safe pallet transport wo...Jump to post
This might be a stupid question, but how does an airline plan for a flight like this? Is there a 3 engine profile for flight planning? I have twice been in the flight deck of a Tristar on a two engine ferry flight. We had removed the fan blades, and boroscoped the other engines etc, and climbed on ...Jump to post
Just read the story. Engine shut down after take off and aircraft returned. I was a BA B744 engineer for many years in Europe. Can someone explain what a blown engine is?. Is this an American slang for "shut down". We don't use the term here. Or is there something that fox news does not ye...Jump to post
With the introduction of proper galley doors in the very early jets like the Comet-4, Caravelle, DC-8, B-707 and/or CV-880 - it got standardized, left for passengers, right side for services, with a few exceptions like the B-727-200. The Comet 4 had passenger doors at Forward Right and Aft Left. Th...Jump to post
BACF is scope limited to 99 seats so an E195 would be overkill.Jump to post
On the V2500 there is a simple metal flapper just inside the filler neck. Pouring oil in pushes the flapper up, and then it drops down and stops the oil returning. On the RB211, there is a chamber in the oil filler neck that has a float in it. In both engines, when the engine is running, breather pr...Jump to post
It is a Post Flight Report. As a maintenance technician, when I walk into the flight deck of an Airbus, I go to the CDU and print out the PFR. I can then see a summary of the flight, and the ECAM alerts and cautions and class 3 messages. On a A320 it usually says Nil Defects!. A PFR is produced for ...Jump to post
Rolls Royce engines have a secondary flapper valve in the filler neck. I once received a B777 with Trent engine after an 11 hour flight from KUL to ARN., with the filler cap missing on arrival. We found it lying in the fan cowling and refitted it OK. NO oil uplift required. We rarely uplifted oil to...Jump to post
Refueling of most airliners in Europe is carried out by the bowser driver. He will set up the qty and pump fuel until the correct amount is reached. On most aircraft nowadays, this cut off is automatic. The refueller is unlikely to notice that the automatic system has not cut off, as most of them do...Jump to post
40 years ago!!!!
I remember this aircraft landing at BAH. It parked on a remote stand for refueling and we could see it from the Gulf Air hangar where I then worked. I managed not to get involved, as the hijackers were nasty in those days.
I think the guys did OK. The fire is way too big for a small hand held fire extinguisher, so wait for the experts to arrive. They can spray the firs from a safe distance. Go close to that machine you may injure yourself. Let it burn, its a machine.Jump to post
I don't remember any autostart feature in those birds and it isn't in the manual but maybe I missed something. I don't know anything about the computer flight sims. On the B744 Autostart was a customer option, but most aircraft had it fitted. We once had a delivery flight at LHR en route to somewhe...Jump to post
The RR Spey had water injection in some models. At Gulf Air our BAC 111-400 had water injection. It was essential for operations during summer days. the engines were flat rated at ISA, and when it was 35degC the performance was very poor without water, so the water was injected, which allowed the po...Jump to post
Watching the other film on you tube taken in the LGW? hangar, I can see the plus side. The driver can see where the aircraft is going. Driving a B737 into a hangar with a TBL you can see very little from the cab and rely on your co workers. With this machine you can see where you are goingJump to post
Not unheard of. I have been involved with two cases. Both times it was the nose axle that sheared off just inboard of the wheel. Can result in a noseleg replacement, not just a wheel change.Jump to post
I have seen it happen at ARN on an A320. We plug in a ground heater on the nightstop aircraft to keep it warm. Normally this works OK. But this night the crew that arrived with the aircraft read their SOPs and it said that if minus degrees, close the outflow vales by pressing the ditching button. Th...Jump to post
I assumed there was a customer option or something comparable for an CPU/avionics conversion program that possibly involved liquid cooling. Basic answer is no. Most A320 aircraft computors have the same processor that was fitted in 1987, running the same software. Changing either is very expensive ...Jump to post
A350 hydraulics indeed run at 5000 PSI, same as A380. However I don't know if that fact has any bearing on the item at hand The cooling radiator in the fuel tanks is for the case drain flow. In a hydraulic pump a small flow of fluid is used to cool the pump and is then led away separately through a...Jump to post
So what is different about the A350.? There are thousands of B737 (and many other aircraft) with hydraulic cooling grids in the fuel tanks and no fuel inerting system. Why are these not grounded until fuel inerting is fitted? Must be a fundamental difference in the A350 case drain cooling system ove...Jump to post
It is operated by HP fuel pressure, not hydraulics. It is a Variable stator vane actuator. You can see the linkage in the photo. That row of 7 horizontal levers goes right around the engine and opens and closes the stator vanes. All high bypass jet engines have something similar. The Vanes are close...Jump to post
Anytime anything happens to the aircraft, such as a lightning strike, the crew contacts dispatch and maintenance control. Those two departments along with pilots determine the best course of action, in this case continue. About four years ago BA operations changed their policy about in flight event...Jump to post
When I worked in BAH in 1980, the BAH FIR was the only one in the Gulf. It went from Iraq to India. The control room was on the ramp at Bahrain airport, and I knew a couple of Swedes who worked there. I popped in for coffee when they were on nights. Two controllers ran the whole Gulf!!!

It sounds pretty serious to have all the flaps go at once. Sand? The flaps are designed to all fail at once. If one flap stuck and the other side moved, the ailerons would be overpowered and you are in trouble. All airliner flap systems have an assymmetry detector system that locks the flaps if any...Jump to post
The chance of any damage being done is nearly zero. It would be impossible to throw these coins into the core, unless you were really trying hard and standing in the nose cowl. With the engine running they would never enter the core, they would be centrifuged out. The worst that could happen would b...Jump to post
Please correct me if I'm talking rubbish, as my knowledge on ETOPS is not all that great...
But I thought airlines have to get their aircraft certified to fly ETOPS routes
Perhaps they fly over Iceland. Then they don't need ETOPS.
Yes. I had a walkie talkie airband radio and talked to the pilots with it. But as an airline we only had one frequency to use, but as we usually only had one aircraft on the ground it worked OK. I used it when I performed deicing release at remote stands. I could sit in the van and release the aircr...Jump to post
I worked as a ramp engineer at ARN for many years. I would say that aircraft engineers would only be seen on the headset for B787 or larger aircraft. I worked for BA, and the loader did the headset normally. I would do it only with a known problem. We had a radio in the office, and it was much more ...Jump to post
I worked for Gulf Air in BAH when the BA Concorde flew to LHR every morning at 1000. I once had a senior BA manager with me.When he was to return to LHR I asked if he wanted me to book him on the Concorde, or the GF Tristar which both left at 1000. Tristar of course, he said, stand up bar in First C...Jump to post
Check out this thread from 2006. The aircraft spotter took the picture and saw the engine losing parts. He called the tower whop advised the crew. The crew had noticed a small anomaly, but were going to continue to destination. After the call they returned to ARN and we found two sq metres of C duct...Jump to post
The type A doors on the Tristar were all electrically powered, open and close. The counterbalance was loaded as the door was closed, and unloaded as it opened. There was a manual crank stored in the flight deck, but this was never used in normal operation. Closing the door with the crank was very ha...Jump to post
As a topical comment. On the BA B747-400 the FMS was getting old a few years ago. The BA engineers had to actively delete unused way points and airports to get them into the memory. The memory was in kilobytes. There was an active program to split the FMS database in two. One for westbound, and one ...Jump to post
In the good old days on the Tristar there was a flight engineer sitting there who controlled it all himself. In the Middle East, packs were required. So the standard engine start was as follows. The APU was used and it was supplying Nbr 2 pack. Nbr 3 engine start selected. The engine winds up and th...Jump to post
I am willing to bet that this doesn't happen in Europe where there are more stringent consumer protections than what we get in the USA. Two things happened in Europe.

Not sure why any crewmember would need a rest area for flights that short.

ARN to BWI is almost 3600 nm great-circle distance, or approximately 9 hours of scheduled flight time eastbound (against the headwinds).
The jetstream goes East. The flight time is longer Westbound.
When most of Europe was grounded by the Icelandic volcano, I was working in ARN and met the Qatar A330 from DOH, as we were open for business. The crew had a very close look at the engines during their PDC and called me over as they found evidence of volcanic ash in the exhausts. But it was only san...Jump to post
But letting potable water drain onto the ground is discouraged when the temps are below zero. Then the water freezes, and the pilot slips over the next departure doing his walk round.
