Seems like yesterday my brother was working as a trauma surgeon in Sarajevo with Serbs taking potshots at him. It was the French peacekeepers that kept the Serbs at bay.
Times change I suppose.
One day within the last 2 weeks, A321 flights from a US mid continent hub to the west coast (~1850ish miles) were payload restricted/pax limited. This is a common occurrence. That may have something to do with the need to carry extra fuel due to crappy weather hitting the West Coast for the last mo...Jump to post
What was the range of the first A321-100. The -100 was 2300nm and the -200 started out at 2650nm I would like to offer that those numbers are a little bit optimistic imho. Airbus marketing numbers. I wouldn't say so. I flew early build 321s with 89t mtow on sector lengths approaching 6 hours. That ...Jump to post
very versatile and capable airplane :checkmark: Bang on. Best performing twin out of hot high like Bogota and Sanaa. Also an incredible aircraft for the likes of Emirates to open up new markets.

Arguably, from Yeltsin onwards, the Russian leadership, civilian and military, has been rotten to the core. What's happening in Ukraine isn't without precedent.

I co-own a car workshop with my brother who manages it. I think most of the manufacturers recommend 10k miles for oil service in the UK.

More A320 than A321 is quite unusual nowadays A lot of India's regional airport infrastructure requires upgrading by way of runway and apron strength,terminal capacity etc. The 321/739 are also in a higher ARFF category.

A sample value of one isn't very valuable. I remember reading some information that Boeing provided that for a similar level of engine technology a twin was ~5% more efficient than a quad.

Another consideration in the use of derate during climb is exposure to atmospheric contaminants. If you're flying in heavily polluted areas then it probably isn't wise to use a greater derate prolonging your time down low. The newer engines, especially the Trent 1000, seem to be more vulnerable to p...Jump to post
From what I have heard, the A340 engines would regularly overtemp EGT if it was hot and/or high, and require thrust reduction. :) Nope, not regular at all.

There's not many airlines I actively avoid for fear of safety, but MS is definitely one of them.

The terminology you are using is unhelpful.

Yes, there is a market for that where airlines are using the full capabilities of an XLR - however I suspect that market numbers in the hundreds of frames, or a small % (less than 3%) of SA deliveries over the next 20 years, which could be over 30,000 I seem to recall having these same debates with...Jump to post
The thing that is missing in this analysis is that the XLR brings different economics to the field and that the market has changed quite a lot. Compare the average density of a 1990 747 vs a 2022 787 and you will see that the density has dropped quite a lot in favor of more spacious business class....Jump to post
Again. I’ll repeat my comment. Pokhara is at about 2700 feet. Kathmandu is at 4300 feet. Neither are high altitude. You've missed the jist of my post. These airports nestled in valleys are subject to a lot of performance considerations and from the little I know, the atr72 is not a "good perfo...Jump to post
I simply think they began to stall, had a small wing drop, tried to raise the wing with aileron (the natural tendency) which in turn stalled that inner wing even more increasing the roll. Thanks for the charts.I agree with your theory. I'd be surprised if they could maintain a 5% gradient on the mi...Jump to post
Pokhara is at 2697 feet. Hardly high altitude. PIA assessed the atr72 and found its performance to be unacceptable for flights in Himalaya. Older atr72s can be procured at low cost and as the saying goes beggars can't be choosers. If I get a chance, I'll do a google tonight and try to find some per...Jump to post
What's an ATR "classic"? I thought the only upgrade to the family since EIS in 1985 was the introduction of the PW127 series engines in the mid 90s, and the cockpit update for the -600. This plane was a -500. Anything pre -600. The differences are substantial. Totally re-worked cockpit wh...Jump to post
It could also be a VMC roll. Yeah from the exterior video it does look more like a VMCA situation rather than an aerodynamic stall with a wing drop. A stall would usually encounter buffeting and an erratic flight path before a wing drop, and that wing drop wouldn’t usually be to such a high AoB. A ...Jump to post
This is what the A321XLR could be really useful for. As it is, AI has a bunch of 788s that could be used to fly these routes. The 777s would be for DEL and BOM primarily.

The V2500 was a consistent revenue stream for RR until they sold their stake and reduced their role in it to parts contractor.

This is in contrast to RR, who seems to largely "go it alone" on their projects - RB211 (747, 757, 767, L1011) Trent 700 (A330), 800 (777), 500 (A340NG), 900 (A380), 1000 (787), XWB (A350).

Had they not pottered about in non-rvsm doing silly marketing stuff, they would have had an endurance of about 15 hours.

No 80k engines are on offer. The newest build standard for the Genx is the P3 which can be optioned for 78K. Both GE and RR are focusing on increasing the longevity and reliability of the engines. The durability of the engines is nowhere near where they would like it to be.Jump to post

There doesn't have to be a practical difference in fuel offload. The key fact is the A330 is so much bigger, heavier and more expensive for no practical difference in fuel offload.
