So the landing weight would have played a part in it.
Just like ANY sector!! Hardly limiting in the AV-ML case!

15-20 knots might just be “disgruntled employee speed”! But in seriousness it may just be that there was a big queue for 34R and they were taxiing more slowly. No point racing down there at 30kts just to sit there in gridlock

Max speed 30. But can’t ride the brakes like a 737, cause you’re worried about brake temps.

Correct technique is to brake down to 10kts, and allow it to accelerate slowly back to 30, then repeat. Most drivers will only brake down to 20kts, some 15.

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.

Yep... apologies for stealing the direction! Just a quick conversation piece as I’ve seen it a couple of times lately where no queue down the end, and nobody on final 34R... back to my rain-delayed big bash!

Disregard, asked and answered I see.

A320/1 Brake temps on 34R are a real issue at heavy weights or strong northerly winds.

the problem is, if you follow the Airbus recommendation and accelerate to 30 kts, then brake to 10, you will hit your brake temp limit, guaranteed.

I find only allowing the bus to go to 20 kts, then slowing her down to a couple of knots prevents this as brake energy absorption is exponential the faster you go.

I see where you're going with this, but the Western Ring Road is a nightmare at any time of the day with all the road works for the West Gate tunnel....

Maybe we're overthinking this - it's less than an hour's drive AV - ML. If the busses were available in reasonable time, then the pax and bags are delivered to ML say 90 minutes after landing at AV. Take the "guaranteed" option in a similar timeframe to flying them up, without all the associated refuelling / weather / ATC uncertainties?
