Re: Do commercial pilots still carry bags with maps and charts given flight deck automation.

Our flight bags in those days were very heavy, and the endless manual revisions were not much fun either! Don´t miss the paper revision work, but at least you potentially noticed some of the changes. Harder with the electronic versions, some of which have a slow and cumbersome process. Still carryi...

Re: Maximum gross weight step climb question

It does in terms of general step climb procedure. However, both 787 and A350 will start higher (approx 36,37 at MTOW) and will climb higher a bit quicker. In many cases up to F430, depending on ZFW. Cheers, Adam A heavy 787 will start at approximately FL330, not sure about the A350. 430 will only b...

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.
