Re: APU Usage

Another thing to consider is APU start cycles - sometimes it’s cheaper to keep it running, rather than shutting it down after taxi in and re-starting it before departure. However, it’s a bit of black magic, depending on airline maintenance contracts etc, company policy, price of ground power at a pa...

Re: Brakes and brake fans

One difference is that Airbii don’t have wheel well fire detection systems and have a 300 deg C brake temperature limit for takeoff, in order to prevent fire in case of Hyd fluid leak. This 300 degrees limit is quite easy to exceed on landing and the brake fans are there to dissipate the heat on sho...

Can’t vouch for the 737, or the 747, but the level of automation in the 777/787 is pretty much the same as A330/350 - they are all very automated planes and fairly similar in operation.

The A v B debate is significantly overrated - and I speak from experience flying A320/330 and 787.

At low weights is the key word. A 787-9 flying long distances won't be at low weights. The last thing you want at MTOM after an engine failure is for the remaining engine to deliver less power. IMO, it's a safety feature, not a performance booster. Well, at high weights Vmc is generally not an issue.
