It's not a problem to fly a longer route on the A319. 737 BBJ can do a very long flights. It's all about economics and payload.

Re: Fokker 50 Speeds

How slow is it? Slower than the ATR-72?
Speed is only one of many, many aspects. For instance the Q400 is very fast, but there's always a price to pay for that. It consumes more fuel and has engines that are twice more powerful (5000 hp), while seating roughly the same amount of pax as the ATR-72

Re: Incredible footage of Rada Airlines IL-62 t/o

Wouldn't say 2500m is that short unless you are high up. The Il-62 is still a long-haul plane, and a fairly old one at that. Most modern airliners with comparable range require more than 2,500 m at MTOW. I agree. 2500 m is perfectly fine for a mid range twin, but for an older cargo quad at the high...

There are few YouTube cockpit videos with Azure's ATR 72's. Approach / flare speed was very close to 120 knots. Of course it depends on landing weight as well. I suspect that the Q400 might be a bit faster though.
