I am going through Instruments questions and there's one I really don't understand EASA's reasoning. And I think the difference between inner and outer loop are fairly clear.
In an autopilot system, the flight path modes are:
1) Pitch attitude hold.
2) IAS and Mach speed hold.
3) Altitude hold.
4) Glide intercept and track.
The combination regrouping all the correct statements is:
A) 4 [my answer]
B) 2, 3, 4 [corect answer]
C) 3
D) 1, 2, 3, 4
4 is pretty clear, but I don't understand what 2 and 3 have to do with the flight path. Altitude is a barometric setting which changes with meteorological conditions from place to place, and we can maintain a speed also during a climb or descend anyway. For example, if a plane slows down on an ILS, RoD decreases and vice-versa to stay on the path to the runway.
