Qantas Power Runs

[feet on the dash]

Why was "the city of shepperton" a 747-200 doing power runs at CNS this morning with all four engines running whilst still connected to the international gate?
No tug attached just a little chock under the nose wheels!
Is this the new "we are the only airline"mentality?

I know that this is speculation, but, I assure you that it would not have been full power (probably about 70% N1 on one engine only (the others at idle) and it would have been cleared through ATC and the Safety Officers would have been in position. There are a small number of MEL's that require thrust slightly above idle to verify a requirement prior to dispatch.

Going Boeing,fine but do you do the runs still connected to the terminal?

Still speculating... but there is negligible safety concern doing a run as GB described at the terminal. Potentially done to investigate and clear a minor fault before departure... Similar in principle to running up a piston to remove deposits on the plugs.

Sad, really - setting out to make someone look like a tosser and ending up making one of yourself.

Suppose the Terminal is as good as anything to hang on to when doing your run up?????

Since when is the "we are the only airline" mentality new?
