Where did they come up with the 'one aircraft taxiing at a time' rule? Is it from MATS or just something they came up with in Perth?
And if you're going to restrict the use of the taxiways to one aircraft at a time, why not just use RWY 21 with a shorter taxi time (i.e. 3-4 mins) and double the rate you can get aircraft away
1. CASA changes to Aerodrome operating standards made last year.. essentially No Stop Bars = Restrict ops to one aircraft on manouevring area during low vis ops
2. 21 is our preferred runway for low vis ops but we cant nominate a wet runway if there is any downwind
