Trying to get my head around this question but I don't seem to agree with the prescribed answer.
Qn: You are established on the localiser to the aerodrome on a heading of 220. If you adjust the dial of the OBS to read 110, what will happen to the position of the CDI needle?
Ans: Nothing
That intuitively does not make sense since I would expect a CDI deflection commensurate with the degree by which the current heading deviates from the intended/selected track on the OBS.
Thoughts please?
