Questions pilots ask

Each of these is an extract, printed exactly as it appears in the book — not an article written for the web. No sign-up, nothing to give.

What is flat rating? Why an engine holds a constant thrust up to a corner temperature, and loses it beyond — the idea every reduced-thrust takeoff rests on.
Derate or assumed temperature? How that unused margin is spent on a takeoff, and why only one of the two methods can buy you a lower V1.
Why V1 is not a decision speed The name is close to universal, and it is wrong. By the time V1 is called, the deciding is already behind you.
Does reverse thrust shorten the landing roll? On a dry runway with a high autobrake setting, not by a single foot. Why that is true — and when reverse really does earn its keep.
Compressor stall or engine surge? Not the same thing, and the difference matters. What a surge really is — told as a crowd at a turnstile.
Why one ground power unit is not enough A parked 787 can need more power than a single cart can give. What each one feeds, and what stays dark with only one.
Why not GPS only? Why an airliner does not navigate on satellites alone, and what the blended GPS-inertial position really is.
What the thrust levers actually command They are not connected to the engines. What they really ask for, and what is lost in alternate mode.

These books explain how and why. They carry no operational authority: always verify against your operator’s FCOM, FCTM, AOM and current procedures, which are the only official sources.
