Dear all, A few years back I was a regular passenger on Austrian's F70/F100 fleet, totaling about 100 flights over the years. In retrospect, I could observe a few particularities in regards to its wing and air brake configuration that set it apart from the ubiquitous A320 and B737 families. First, t...Jump to post
In Munich, the runways are specifically assigned for landings (08R and 26R) and departures (08L and 26L). The reason is that the runways are longitudinally displaced in such a way that taxi times for both incoming and departing traffic are minimized. Thanks for the info. I remember going with my co...Jump to post
A few famous examples from Europe: (...) Munich - similar config with 08/26. They are using the runways depending on departure, to separate flows north/south. Basically traffic south (eg Italy) will get the southern rwy while northbound (say nordic countries) will use northern ones. Dear gloom, In ...Jump to post
Very interesting video has emerged... https://mobile.twitter.com/breakingavnews/status/1274034217727508488 While somewhat amusing, I also noticed some dangerous actions by the people involved: just imagine the guy attempting to stop the plane by pushing against the MLG strut would lose balance and ...Jump to post
(A380 backup flight control) Not really sure. The A380, rather logically, seems to have systems that are halfway between the A330 and the A350. For example, it has a trim tank like the A330 for CG control, and it has EBHAs and EHAs (electrohydraulic actuators) for backup control like the A350. Dear...Jump to post
Interesting read! This triggers one more question: how much fuel could possibly be saved by the means of giving up the inherent stability? If we define "unstable" as "the horizontal stabilizer will not provide a continuous down force in normal flight" (I am not sure about this de...Jump to post
The direct family tree for the designs is: A330 from A300B11 design studies A340 from A300B9 design studies B9 and B11 are switched around sometimes in articles and documents, but I've been assured the above is correct. Dear northstar, Many thanks for your insightful answer, it was a highly interes...Jump to post
Fun anecdote regarding autobrake: Back in 2005, I was traveling aboard a CRJ200 from Austrian, taxiing to the departure runway 34 at VIE. As it is a rather long way to go, the pilot was throttling up to get the plane to speed. Apparently, he pushed the throttle too much and when he retarded, the bra...Jump to post
The triple chime, ("dit, dit, dit") is called the "triple click" and it does not indicate AP disengagement. It indicates an automatic mode reversion. AP disengagement is indicated by the "cavalry charge" sound. Ok, I stand corrected. It is the cavalry charge "blee...Jump to post
I would think that, while your idea might sound interesting, there are likely the following drawbacks: - Aircraft compatibility. Traditional tug need to connect to different aircraft by the means of different bars. Some exotic aircraft even need to carry their own tow bar in order to get pushed. - P...Jump to post
Dear all, I was thinking about tracing back the technical evolution of Airbus airliners. This means, how did the technology evolve from older models into the current line-up. For some aircraft it's pretty straightforward: Let's take the A330 NEO - it's based on the CEO with some refined engines (RR ...Jump to post

One of my very first flights was on the Caravelle. Back in 1982, we went home from Gran Canaria Island to Cologne CGN. I remember it had a green cheatline and vertical stabilizer. Does anyone know which airline it could have been?
A great part of the A380s crown is unsuitable for seating passengers due to ceiling height and the staircase. That is where airlines placed their showers and oversized toilets. The 777 didn't really have these unusable areas. The 747 did, but it was all above the main cabin, which was impractical t...Jump to post
Yes, that is correct. The gear doors only retract if you have hydraulic pressure. I don't know which hydraulic system runs the gear on the A320, but since they seem to have lost both engines it is a bit of a moot point in this case. Dear Starlionblue, The gear is operated by the GREEN hydraulic sys...Jump to post
Dear all, The height of the landing gear is - as many other design choices - a compromise. Advantages of a taller landing gear: - Higher rotation angle possible - Higher bank angle possible before risking a wingtip or engine nacelle strike - Possibility to further stretch the fuselage (e.g. A320 to ...Jump to post
Dear denny, Let me try go through the numbers: With a OEW of 51.2t (I am surprised how light that plane is!) and a MTOW of 106,1t, the aircraft has 54,9t to share among payload and fuel. Assuming 112 pax (typical 2-class) and 4t of cargo, we have about 15t of payload, leaving about 40t for fuel. Ass...Jump to post
According to Wikipedia, the dry weights of the respective engines are as follows:
Trent 700 (A332/A333); 6'160kg
Trent 7000 (A338/A339): 6'445kg
Therefore, the engine upgrade (without housing and attachment) would add only 570kg to the structural weight.
These birds must have been among the very first - 200s built, isn't it? As you can see in the OP they have cn’s in the 50-60s range. Hello! Precisely. In the meantime I have researched a little.

Austrian has operated a number of cargo-only flights from China to VIE using their 777-200ER. Two such flights were announced to have brought no less than 130t (65t per aircraft) back to Austria - an impressive figure for a pax-configured aircraft. Pictures showed boxes being stowed on pax seats and...Jump to post
That's because the OP is still very enthusiastic at something that's perhaps still new or unusual for that person. Spot on! :-) Usually, Austrian Airlines isn't flying any further than US west coast, Japan and South Africa, none of which brings a 77E to its payload-range limit. Now, the rescue flig...Jump to post
Dear all, I noticed a flight operated by OS yesterday, using a 777-200ER OE-LPD from Vienna to Sydney. It is likely a rescue flight to bring back stranded EU citizens. https://www.flightradar24.com/data/aircraft/oe-lpd I know that in the past, a BA 747-400 did a LHR-SYD run and IIRC a 330-200 was on...Jump to post
Interesting thread indeed.
While I could imagine that the task of programming a digital FBW is already highly complex - but how the heck did they manage to implement this complex logic in an analog aircraft like the Concorde?
So basically the vertical stabilizer becomes a horizontal stab and vice-versa...Jump to post
Is 2132/2750 the prop RPM? This does not indicate engine power. The props are variable pitch, so the RPM would remain pretty much the same in the cruise regardless of power settings. FYI, as far as I remember, the props of modern Turboprop aircraft revolve at significantly lower RPM, like 800-900. ...Jump to post

The nacelle is too close on the 321 to do it, and anyway the 2L door on future build 321s is going away.
On a side note, airlines seem to ban flight numbers that have encountered a catastrophic accident. E. G. AF447.Jump to post
Well to conclude in regards to the initial question the list of jet airliners with no catastrophic accidents, no matter the cause, would be: -Dassault Mercure -Airbus A340 -Airbus A380 -Bombardier C-Series -Boeing 787 -Ilyushin Il-96 (Without respecting subtypes, with them the list would be a lot l...Jump to post

Austrian quite frequently uses 772 and sometimes also 763 on VIE-FRA hauls. One flight attendant explained that this was done because of capacity needs (the plane was packed indeed). The crew currency argument seems quite plausible to me as well. Remember that Swiss has introduced the 77W over the l...Jump to post

Dear all, Let me try to get back to the original question and put some numbers on it.
