In General
Assign changes in the arrival speed, including cancelation of restrictions, for sequencing or any other reason after top of descent. It is not unmanageable but just plain inefficient.
ADL
Requesting a readback of the taxiway to enter the apron by. I believe it is in excess of AIP readback requirements. If ATC think it should be read back to ensure the inbound and outbound a/c don't conflict then can a local procedure be published to save on R/T traffic?
SYD
Assigning RWY 07/25 when there is a 15-20 knot southerly blowing and then holding a/c because of delays due to single RWY ops.
I know that they are just doing the bidding of the politicians via the LTOP but it still irks me.
By the way, in the above scenario, if one was to require RWY 16 (L/R) what would be the consequences in the ATC system? Does AsA have a reporting system that captures such instances that gets back to the operators?
