Why is it, that on 90% of occasions (and in my experience I am not exaggerating) that when an approach controller is told of on initial contact, or issues, a speed instruction during the early stages of an approach, such as IAS 250kts, the instruction is never cancelled?
Theoretically, unless told otherwise, the last given speed instruction applies all the way down to the threshold, which is of course ridiculous.
Should the pilot start slowing for localiser and glideslope intercept on his/her own judgement, or would you ATCOs expect this to be queried and confirmed? Who has the responsibility to make the call?
