Dear SQ32, I had been made aware of this new production standard a couple of weeks ago and I think that in particular the option to install 10-abreast Economy seats is an important improvement. Remember how the 777 gradually outclassed the A340? Among other things, the main advantage of the 777 was ...Jump to post
One point in addition to the ones already mentioned (ground taxi, congestion, cost index, slower mach numbers) is the EU regulation on passenger rights (EC directive No. 261/2004). It gives passengers the right to claim compensation between 250€ and 600€ for flights delayed by more than 3 hours. The...Jump to post
BTV seems like a neat tool to assist the pilots in using the runway efficiently, reducing the risk of an airplane crawling along the runway after missing the right exit and forcing the next approaching airplane to go around. Wouldn't it be even more useful in the A320, given the mission profile of t...Jump to post
Dear all, Thank you very much for these insights. I definitely learned something. Now I'd like to ask, how do they design the "automatic pitch down in a developing stall" in a straight wing, e.g. for the Q400 or ATR? A higher pitch angle at the wing root wouldn't change the center of lift ...Jump to post
Here is the best I have: This is a very interesting drawing. Take a look at the obvious wing twist from the root to the tip. The angle of attack is significantly higher at the root. Would this design feature induce a stall behavior where the root stalls first, moving the center of lift backwards, t...Jump to post
Swissair is an airline to remember. I had the pleasure to fly with their then brand new MD-11 in Business class from ZRH to JFK in 1991. Impeccable service and great food.

Here an article in German about the second A350 for the Government: https://www.aero.de/news-43926/Olaf-Scholz-jettet-bald-mit-Konrad-Adenauer-um-die-Welt.html This aircraft is named after the first chancellor of FRG from 1949 to 1963, Konrad Adenauer. I just wonder why we need three such aircraft?Jump to post
One sector of aviation not yet mentioned is military aviation.

2. As mentioned, MAX is never used on landing. MED is rarely used in our case. It's quite "sharp". Dear SB, I can confirm the "sharp" braking of MED autobrake on the A320. I once flew as a passenger on an OS A320, returning to Vienna RWY 29 on a late evening. The gate was on the...Jump to post

Dear Musa, Although there is a slight difference in normal cruise speed (M0,82 for the A340-300 vs. M0,85 for the A350), a major difference in flight time most likely comes from different routings. There is no significant restriction for the A340 to operate the ideal route from the Far East to Europ...Jump to post
Dear all, Here is my take on this occurrence, in the form of a hypothetical sequence of events: - A bolt detaches from the nose landing gear during take off roll. - The bolt rolls over the runway surface and hits the rearmost outer tire of the left body gear, wich receives damage in the process. - T...Jump to post

I’m sure they have a good idea what a new 36m wing would do for the A32x family. They might even have studies on 40m wings? Why box the A322/323 into 36m - everyone says it s a new category of plane.

A modern 36m wing with a cleaned up design should give the A320 family a pretty good boost in efficiency. Dear FF, I agree with your statement. The A320 wing is the oldest wing in production at Airbus and only the 3rd wing design they ever made (after the A300 and the A310 which is different from t...Jump to post
Also, it'll be interesting to see just how many carriers take the optional forward fuel tank, and on what type of application.

I'm by no means an expert but my understanding is that on AF447 the FBW system switched off due to a frozen Pitot tube and left two inexperienced pilots fly manually, without them realising what was actually happening.

Just to get an idea - what is the fuel burn penalty of cruising at M0,94 vs. M0,90? I could imagine that for some passengers of this aircraft, a few 1'000USD added cost is acceptable for arriving a bit earlier, still would be interested to know the numbers.
Does the XLR feature anything different to improve fuel burn from the normal 32Q? So far it just looks like a boring upgrade with nothing too exciting.

Dear Convair, I am not entirely sure if the author may not have meant "double slotted flaps", as the DC10's flaps were single slotted.

Just a practical question: In the case of tri-jets, in particular the DC-10 and MD-11, the engine nr. 2 is mounted some 10m above ground. How is the oil level control and top-up performed?

5% contingency is normally not required for this type of flight. Some sort of variable contingency depending on route and conditions is carried. Often several tonnes less than 5%. 0.5 hours of reserve fuel is carried, and typically diversion fuel is also no less than 0.5 hours even if the nearest a...Jump to post
0,6 hours of reserve fuel is just a little on the low side.
A contingency of 5% (5,6t) must be accounted for, plus diversion (a few tons), plus final reserve (3t).
Maybe your assumptions for OEW and flight time are a little on the high side.
