Taxiing down Tango for departure runway 34R in SYD in my 737, and every knot less than 30 sucks the life out of me
Nothing sucks the life out of me is people who use excessive thrust to accelerate to taxi, and then sit on 30 knots riding the brakes. As someone else said, no point if there is a long queue at the holding point anyway.
This is the correct technique from an Airbus manual
On long, straight taxiways, and with no ATC or other ground traffic constraints, the PF should allow the aircraft to accelerate to 30 kt, and should then use one smooth brake application to decelerate to 10 kt. The PF should avoid continuous brake applications.
If some people really find it so unbearable to sit in the cockpit an extra 1 or 2 minutes because they might have to taxi a bit slower, then maybe they should seriously consider a career change. Will an extra 1or 2 minutes taxiing really have such an impact on your day ?
Either follow the published procedure or get another career.
