Right on all accounts, 747Teach and, it is recommended to maintain at least 160 knots of final to assure proper RAT rpm. But, beware of icing. Also, if it were me, I would not use the BtoA PTU (on final) as the B system provides all the control you would need. During landing, the RAT will not provid...Jump to post
Well Minuteman, notice in your diagram that the mixer is "fitted" to the hot stream only, so that it mixes the hot stream with the bypass air for quiet(er) operation. And yes they are subject to continued stress, in fact I had one depart the number two engine on a B707-331 some years ago, while land...Jump to post
Actually, propeller alcohol fluid deicing is still used on some models of light aircraft....and on the wing as well. The TKS system works quite well.
Jet engines use bleed air for anti-ice. However, it must be switched on in time otherwise it's DEICE time....with surprising results.
Ganymed--- On the early DC8's, yes they did increase fuel consumption, and their was a Douglas service bulletin to remove the reversers from some models of the DC8, because as you know, thrust reverse is not used in calculating field length requirements for FAA certification, unlike the UKCAA which ...Jump to post
Runway 18 at FRA is used only for takeoffs due to noise and obstructions.
The westerly runways at LHR are alternated for takeoffs and landings...ie: landings on one in the morning and takeoffs in the afternoons and evenings....also for noise considerations.
ANCIENT would be a better description.Jump to post
Cannot say about other asian airlines, but when I worked for SIA the female F/A's were hired on 4 year contracts, that usually were not renewed.....always fresh new faces to be seen.Jump to post
As you can clearly see from the photo, the translating cowl has moved aft. What you cannot see are the blocker doors inside, which divert the FAN thrust forward (actually at an angle). Note that the hot stream is NOT diverted.
Works good, lasts a long time.
You're wrong, Flight152, the picture of the Alitalia DC8 clearly showes the thrust reverser. Have a close look, you can see the tracks on which it moves aft. How do I know you ask.....the chief production test pilot at Douglas was a good friend of mine. When the engine is removed, the thrust reverse...Jump to post
Actually, DC-10inLB, many of the older 707's and DC8's with turbojets did not have water injection, only a few models. And when the heavier (intercontinental) 707 was introduced, it had JT4 (no water) engines instead of JT3's. Convair 880...no water injection either.Jump to post
There is no correction for the EPR setting on the number two engine on the L1011 due to the 'S' duct. In addition, in the design of the TriStar, the curve of the 'S' duct was kept at less than one quarter the radius of the intake diameter to achieve the desired objective, ie: straight thru performan...Jump to post
Jetguy-- The 411 was Cessna's first cabin-class twin and had a few problems in the hands of inexperienced pilots. However, if properly flown, it is quite fast and very comfortable and quiet. I delivered two from the factory in 1967 and the Cessna training provided was comprehensive and well presente...Jump to post
Quite a lot really, shorter, different flaps, less fuel, lower weights, etc.
Optimised for short-medimum flights.
One model of the 707 was actually shorter than a 720, 707-138 developed for Qantas. Lots of fuel, very long range, nice machine. John Travolta has one. Stage III hushkits I believe.
Flap settings are, 4 10 18 22 27 (not used) 33 42 (blocked on most aircraft). 4, 10, 18, 22 are approved for takeoff, depending on the individual airline procedures. The slats deploy fully when the flap HANDLE moves beyond the 3 degree position. DLC activates when the flap HANDLE is moved beyond the...Jump to post
Some may be interested in what happens when aircraft has a birdstrike at low level-- In 1985 at Khartoum, Sudan an Ethiopian Airlines B727 struck an (estimated) 10 pound buzzard at 330 knots IAS at 4000 AGL. The buzzard went thru: The radome, The forward pressure bulkhead, Broke the First Officers l...Jump to post
Well Ceilidh, that was the plan, however the new owners have the first two aircraft destined for another carrier (E Asia) and they do not want to terminate the rear spar AD prior to delivery. As the aeroplanes would be leased, it would be the owners responsibility to deliver them with a fresh 'C' ch...Jump to post
