Hi Telstar,
I note that your company procs state "164 knots (-800). This is acceptable to ATC as 160kts speed required."
As far as i understand, this has not been agreed for LTMA airfields, if it was it was in the dim and distant past and needs to be renegotiated
I do know that we are setting up a working group with airlines to try to figure out the best compromise of speeds on final so that ATC can land the required number of aircraft per hour and aircraft can have a stable approach by 1,000agl.
BUT until that has been agreed the AIP for all LTMA airfields says that pilots must fly speed instructions accurately (with no leeway). If they are unable to do so they should inform ATC.
