10.64 hours average utilisation in 2019 for DL large narrowbody above 150 seats.

Jump to postI tend to spend a lot of time in and around the Holy sites in Makkah and Madinah. Of late I've been noticing a lot of Europeans on pilgrimages, who, when asked, all seem to be flying with Pegasus.
Is there a concerted effort by Pegasus targeting this traffic or mere coincidence?
Odd question, are there 737-900ERs available that Delta could (and would) buy another batch? Their utilization is pretty high (8 to just over 9 hours per day. With DL's high revenue, lower utilization model, I see a need for more new aircraft (A321NEOs, eventually -10 MAX), but more for cheap *larg...

Jump to postI think I'm right in saying (any Airbus pilots or experts please correct me if I'm wrong). Modern Airbus aircraft starting from the A320 don't use predefined flap angles like Boeing aircraft. For example, if you use flaps 2 for takeoff, the actual angle of the trailing edge flaps will vary dependin...
Jump to postThis is not additional takeoff weight above the airframe’s MTOW. That has not changed. Glad to see there's someone on these threads with above average reading comprehension.

Jump to postWait, really? Why? I believe its a RR engine limitation... only because thats the only difference between the classic and the neo. Crosswind limit is 35 for landing and 30 for takeoff.

During this phase, there was consid...

Jump to postIt seems like at least on Boeings, there's a significant difference between flap settings used for takeoff on the 737 and the 777/747. In the 737NG, seemingly 1° and 5° are the main ones, with 1° being preferred for weights close to MTOW(and generally also used with a less de-rated N1 setting) beca...

So essentially, in my understanding, aircraft like the B777 and A350 were developed primarily as medium and long haul lift. Nevertheless, the 777 has ended up in heavy short-distance operation in some parts of the world, or in a mix of short some days, and long haul others. JAL's A359s have been us...
