In the 777, gear down, the fuel flow is approaching twice normal at a slower speed; the aircraft ceiling comes down dramatically (as I'd expect the airframe to do!) There's potential here to create a dire situation out of an uncomfortable one.
You can't write checklists to cover all eventualities, so sometimes pilots have to fall back on logic and experience. I'm not saying ignore the QRH but IMHO you have to be aware of the direction it might take you (down!) before you follow it to the letter...
Logic and experience.
Yup, that will do it.
Younger guys need to realise that sometimes...it is best not to jump to conclusions....and put yourself in a more dis-advantagious situation.
IE: Take your time and evaluate, in these scenarios.
