The whole run in from ivo Southwold is flown pretty much level at the assigned altitude.
That said, it shouldn't take more than 2 or 3 holds to nail the timing. 😳
Two points for you.
Firstly, the multiple holds is as much about getting everyone airborne in a position to push on time as it is about fettling the ToT. Think of it like the IOT five minutes before the five minutes before. The TOT really only needs a single dog leg if everyone has taken off roughly on time.
Secondly, IAS and TAS are irrelevant. They’ll only be looking at GS for timing purposes. They’ll have a good idea of sensible IAS to fly to give the correct GS.
