Why the red bit (and not all purple)?

Or Vice Versa?

 

[Hvr]

Looks rather plane to me. Is there a tail behind it?

 

[lathiat]

So the same as the upcoming PER-LHR flight from QF then

The line becomes red when the aircraft ascends from 41,000 feet to 43,000 feet. I can only assume that Flight Radar paints the line at this altitude red as it's above the normal service ceiling.

In standard QF four class config, how many could that aircraft seat?

I think you'll find that the 787's service ceiling is 43,000. Probably 43,100...just to allow FL430 to be used.

So, dumb question, what happens above the 'ceiling' or is it just that the aircraft does not have enough lift to fly above the ceiling height?

 

[jb747]

It's the vertical edge of the world....so if you go above, you'll fall off.

Nothing happens. It will be defined by a bunch of things. The ability of the pressurisation system to maintain a given level, perhaps in a degraded state. There will be a required rate of climb, and stall margin...probably of around 300 fpm and 1.2 g. Go above, and the aircraft could well be stalled by a normal en-route turn.

Didn't realise a 787 can do 18 hours non stop. Anyone know why did Boeing send a plane up to do this?

We're all talking about it and bet we're not the only ones. That alone might be a good reason to do this!

I am guessing there was no paxs and no freight so not huge weight loaded onto the plane

It will have been part of other testing (ie. needed flight hours testing something anyway), but the publicity is a good secondary reason.
