I think SAS was the last major carrier to fly DC-8s across the Atlantic. 1983 I think.

Jump to postCalculating oil consumption is critical to ETOPs. In order to do so properly, you must assume the oil was serviced properly before. If no oil was added for the prior leg, and was entered as serviced when it wasn’t, then at the end of the next leg, oil would be added for both legs, but the flight tim...
Jump to postYou are very correct, those little things burn up the oil. Much more so compared to the IAE. I don’t have the hi-limit consumption rate on hand, but I’m sure it’s more than a pint per hour. GE engines have always used more oil than competitors. The reason why is the oil scavenge system. They must th...
Jump to postI saw a cargo A340-600 at DFW yesterday. Owner was European Cargo.
Jump to postIn the early nineties, I flew AA MD-80 from SJC-SFO and then on to ORD
Jump to postOh my goodness. I just had nightmares about a Professor who studied at Caltech giving us mixed units problems in my Aero Engineering ugrad. Seriously, slugs as a unit of mass? Pound mass vs pound force. SI was just simply more elegant. Unfortunately, having grown up in the US I do think in the so c...
Jump to postAs was stated before, on Airbus, all maintenance manual data such as torques and dimensions are given in metric, with imperial values in parenthesis. Honestly, when working with small dimensions, millimeters are much easier to work with. Brake wear limits are given in millimeters, and I have a milli...
Jump to postAirlines cannot alter tire/wheel size. They can choose from different tire manufacturers. As was mentioned earlier, they can also select an approved wheel half supplier. I know 767’s have different wheel types, because they look different. Bendix is one option. Goodrich and ABSC are other manufactur...
Jump to postNope. Dunno what your airline you are from, but 767-200 are hyd t/r all else pnuematic
Jump to postThere really isn’t much to see up there. You’re not going to find any damage from ground handling. If there is evidence of a bird strike on the SatCom dome, then you would need to go up there. Another possibility would be hail damage inspection work card. For a routine maintenance walk around, the o...
Jump to post767-300s use pneumatics for thrust reversers. They work very well.
Jump to postI would think the crew would want access to the E&E in the event of a fire.
Jump to postAll airliners have forward E&E compartments. On wide bodies, they are accessible from the cabin, narrow bodies they are not. On the 777, the E&E is accessible from the forward cargo. The 787 also has an aft E&E, not accessible from the cabin but from the aft cargo. All E&E compartmen...
Jump to postNever seen this. I’m guessing bird droppings. The warm tailpipe might attract certain types of birds.
Jump to postI’m just wondering what the lockout prodcedure is for an MD-11. I remember on a 767. Installing 3 red lock plates on the outside of the trans cowl and flipping and installing a locking square drive in the center drive unit. Easy enough on the ground, but much more time consuming when you are 2 stori...
Jump to postThere is always a trade off between sophistication and cost. Period..
Jump to postThe flaps on any aircraft, as a rule, will not droop. Take a B747, for instance. The flaps are not driven by an actuator in the sense that the primary flight controls are. The flaps are driven on jackscrews running in transmissions (all that stuff lives under the fairing or canoe) that are driven b...
Jump to postI’m guessing the first few pay steps at DAL are small, and the last step is the big one.
Jump to postNot really. Manufacturers have a “not invented here” mentality.
Jump to postThe chord length is merely a reference length. The actual symbol used in Moment coefficient is l. The reference length is chosen to pertain to the given geometric shape. For an airplane wing, l is the mean chord length.
Jump to postPossible the nose gear mounted taxi light may be replaced by a wing root integrated unit.
Jump to postVFSG’s are for variable frequency electrical systems. A 737, be it an NG or MAX has no such system.
Jump to postThe only welding I ever saw on the airplane was to fix a crack on a pack heat exchanger. That would be in a safe area to weld.
Jump to postActually, you won’t find tire replacement criteria in the AMM, but rather in the individual airlines Procedures Manual. The applicable section on “Wheels and Tires” gives information on tire pressures, replacement criteria and disposition. I’m pretty sure all airlines specify replacing both tires wh...
Jump to postAs was stated earlier, if the tire was found flat on arrival, both the flat tire and the opposite tire have to be replaced. A321 wheels take much longer to change due to brake fans (if equipped). Plus, if the contract maintenance personnel have little experience with these wheels, you are looking at...
Jump to postYou must have flown on a 707-331. They were finally retired in 1979. This was probably planned a long time and there was no point painting them in the new livery unless necessary.
Jump to postThis question is more easily answered with regards to engines. For me, no question, the easiest engine is the RR Trent 892. Most things are mounted on the fan case, which gives much easier access. Fuel control changes are a breeze. It’s not always RR. PW2000s had the edge over the RR211. Late model ...
Jump to postAs with anything technical, it’s not what you know but how to find out what you need to know
Jump to postI remember I was working at ICT when the Continental-Frontier merger took place. I saw Frontier 737s all lined up on a taxiway. They would land, park then takeoff a few hours later. Needless to say, I was puzzled by all this. I was told they were transferring ownership in Kansas because the taxes we...
Jump to postAccording to my research, it was a slat problem. Still had to make an overweight landing.

Jump to postDeactivating the brake fans for a wheel change is a step you don’t skip.......
Jump to postMost people test them anyway. Once you re-instate the circuit breakers, all you do is press the button.
Jump to postWon’t hear anything this year, but they’re definitely exploring smaller used narrow bodies and the A220. Any airline not looking at used is being silly. As much as I want new aircraft, used are a good bargain now. I'd love to see the A220 at AA, but my opinion is the A319s sit feeding hubs, so purc...

Jump to postOn a 777, you can access the forward cargo from the E&E compartment, which itself is accessed from a hatch in the floor in the first class galley. To open that hatch you need to be able to unlock it. The 787 has no such access.
