Ask The Pilot

[Captain Halliday]

Is there a speed limit for taxiing?

If the limit is different at different airports, do you know what it is for SYD?

How, if at all, are these limits enforced?

30kts. Everywhere. Enforced by the airline through the Flight Data Analysis Program. Some airlines will call it different things but basically it monitors certain flight parameters.

Taxi speed, rotation rates, any TCAS/Windshear events, Flap over speeds, etc. If an event has been triggered it’ll flag it in the system.

Adding to AV, there was a limit of 15 knots in parts of Dubai, and there were actually people there with radar guns. Never got a ticket. It’s also 20 knots over the bridge at Changi.

What penalties are there for "speeding"? Is there any leeway like they allegedly do with speed cameras?

Over on Whingepool they're discussing the issues of getting the F1 teams to Oz. They're talking about flights, etc.. One guy wrote this:

QF9 & QF10 flies the Boeing 787-8 directly from London Heathrow to Perth, and vice versa.

Are you suggesting that there is not enough fuel margin in this aircraft to divert the flight path around the conflict zone OR that cargo planes like the Boeing 747-400 are older and less efficient and unable to make this flight?

Thoughts, JB?

Dunno. Perhaps they surgically remove something from the company chief pilot.

There will be issues. Congestion on remaining routes will mean that aircraft won't get levels that they need/want. Some aircraft don't have huge range margins, so you need to lower the payload, or consider fuelling stops. For aircraft flying from Perth, there's any number of drop short alternates within Europe. But, due to the flight times involved, you'd probably want to consider pre-positioning a crew or two. Removal of the ME3 from the mix will offset that to a degree.

I'll have a look at Whirlpool and see what the experts think.

In the grand scheme of things, the race isn't all that important at the moment.

You're right, of course. If they had to cancel it I wouldn't be saddened by it.

@jb747 - are there any specific procedures for departing or landing an A380 or B747 where you want to be as high up as quickly as possible vs get the bird down as steeply as possible (with or without passengers) as opposed to normal departure and landing procedures.

I would expect that the current A380 departed and landings in DXB and AUH want to invoke something like that?

There’s no specific procedures. Operations into war zones isn’t something the airlines really should be doing, so the normal best defence is simply to be somewhere else.

The procedure you allude to, descending rapidly in close, and departing with a steepish, climb, would normally relate to defending against MANPADs, where you stay above them as much as possible, and only operate at low level in close to your airfield, where you hopefully have control of the ground. Steepish descents are easy enough, full speed brake and extend the landing gear. I’m not sure if there’s really any benefit here. You can’t do a great deal about the climb. Full climb power, and hold the flap at about 1, until above about 5,000’. Accelerate then.

The biggest risk, as just shown by Kuwait, will be “friendly” missiles. And most of them aren’t all that height limited.
