I'll see if I can add any answers to Mad Scientists:
How is ranged increased in a headwind?
Range can be very slightly increased by flying at a higher speed, therefore reducing the amount of time you're flying for, and reducing the amount time the headwind can affect you.
What is transport wander for an uncorrected gyro?
Can't figure out how to explain this without lots of diagrams and things. Basically, as you move a gyro across the earth, it continues to point the same way
in space, but the way it points relative to North will change.
Tell me about ETOPS?
I haven't got to this chapter yet, so I don't know the details. But the idea is that, without ETOPS, you're not allowed to be more than a certain distance from a diversion airfield in a twin-engined aircraft. So flight across the Atlantic, for example, would have to be in an aircraft with 3 or more engines (or take a long route). ETOPS enables an operator to operate twin engined aircraft on these routes, once the authority is happy that the operator's procedures are sufficiently safe.
