Qantas Delays/Cancellations

Actually you would use asymmetric reverse. There is very little yaw, and it's easily countered without any additional considerations. Reverse doesn't actually produce much 'reverse' thrust.

Ah OK - I knew that it didn't create much reverse thrust - one of the many things that were argued for a while at Airbus was whether or not to even fit reverse thrust to the inboard engines as the limited gain vs cost etc was seen as marginal. I wasn't sure what it would be like landing with asymmetrical reverse - or whether the systems even allowed it.

As you're aware, reverse thrust isn't really a braking system, and for that reason isn't even considered in most calculations.... But, it is very effective at blasting water off the runway, so that the tyres have greater grip, and so the braking system can work harder. It's well worth the weight for just that benefit.

On landing, (with 767, 747 and 380), you always take the engines to the interlock (i.e. idle reverse). As the locks release (meaning that the translation cowl has stopped moving), you can then select more power. It wasn't uncommon for an engine to fail to release, and after the normal couple of seconds wait, you'd just take whatever you could. Sometimes finger trouble (especially when trying to get four engines) would result in you leaving one behind too.

Seems today’s QF75/76 (SYD-YVR) has been cancelled.

Anyone know the reason why?

QF28 is delayed 12 hours. This was to be the operating aircraft.

Thanks!

On QF35 MEL - SYD; delayed by about 1 hour due to “a late engineering issue that took later to resolve than expected”. VH-QPD being the operating aircraft.

I hope it is actually MEL-SIN not SYD or else you might be later still!

For a differance, QF800 pushed back early.
Will be nice if that continues once we get to SYD

On the bus over to T1 before QF800 was due to land.

US interview people at the transfer desk didn't care about my US flight (QF3). I guess they do that stuff in AKL.

A bus was unloading as I got to transfer, so only waited a minute.
