Hi there,. .. .having flown the DOH-MUC route on Qatar Airways I can only suspect that it has to do with the unusually long runway available at Doha airport (something on the order of 15,000 ft if I remember correctly). At the time, it also took me by surprise taxying on the hammerhead for a northbound departure and not seeing any flap extension. Checking the acceleration time on a stopwatch delivered not too unusual takeoff-run values, though (only a little bit longer but definitely faster than usual upon rotation).. .By the way, there is an ideally located Hotel (Sheraton Doha) located right under the extended runway centerline, so if airplane noise is music to your ears, like it is to mine, then lying in its poolside garden is quite interesting because you can watch aircraft coming in on long final almost to before-touchdown crabbing in crosswind conditions.. .. .Cheers,
