|Quoting prok (Reply 8):|
Full thrust takeoff makes sense to gain some attitude as there are some climb restrictions for crossing the Alps.
Can't imagine the 321 is that weak. Even if you get an immediate left turn towards Vicenza (where you would end up if going to London) there is no rush to climb. There is no emergency turn procedure (engine failure scenario) for the 737s I fly to VCE
, which means no terrain close enough to matter, and we never have to worry about sufficient altitude to clear the Alps. Perhaps a heavy 321 is different.

Yeah I noticed we circled round the airport while climbing out, and there wasn't the usual throttle back/Noise abatement and assumed it was because of the Alps/Dolimites(sp?)
Some of the standard departures involve a long right turn from the north west runway, back to just south of the overhead.
About the thrust reduction after take-off - this isn't inevitable, and there's another thread about it. Take-off thrust is usually higher than climb thrust, but if it takes off with reduced thrust, as it might with a long runway (like VCE
) and lower than max weight, there may be little thrust reduction to notice.
Perhaps an Airbus driver can comment, but there is probably an option to over-ride the thrust reduction after take-off like there is on the 737. A nervous crew might have taken this option with the Alps in mind, but I find that difficult to imagine based on how distant they are from VCE
. I'd go with my theory that they took off with thrust reduced so much that there was hardly any further reduction to climb thrust.
No idea why it would be spooling them up on the taxiway though. We'd do this to shed ice from the fan blades in icing conditions, but not in the ramp, and one engine at a time.
