Taxi reports were always required at GAAPs by AIP, but in Bankstown's case they had excused the requirement in ERSA.
Given the problems they were trying to solve by introducing class D, and how none of them were surface movement related, why can't a similar ERSA entry be made for Bankstown now?
Clearly unless they undertake a significant upgrade including signposting of taxiways and holding points and better lighting, it is actually causing pilots to taxi around with their head down reading a map instead of looking outside at the fairly high levels of surface traffic.
