BA749 Basel - LHR Squawks 7700 and diverts to Stansted

https://fr24.com/BAW76GF/1fc1ea94

Looks like it broke off final approach into LHR and routed to Stansted.

I would expect this to be fuel related after a number of orbits and then a change of stack for more.

Weather in NW London has been horrid for the last half an hour - thunder and hail - and looking at FR24 Heathrow stopped any approaches or departures for a time.

But it was only one full loop in the stack and then one orbit - doesn't seem an unreasonable delay to expect when approaching LHR...

And now the 685 from Innsbruck is going the same way!

Are all these diversions part of the calculation for the environmental impact of a third runway...?

The holding patterns are absolutely crazy

the QR1, BA from BKK, EK from DXB have all been creating funky doodles in the sky

MrsT has just landed at LHR on BA238 from Boston, the approach was broke off due a lightning strike so the crew told them, all safely down now.

Similar flight path and altitude profile to the BA749. The TATL presumably had greater fuel reserves than the short haul, therefore could continue to hold for LHR.

Diversion for weather related closure of LHR does not explain the 7700 though

I guess radio was very busy around EGLL so putting 7700 will get probalby quicker attention from ATC.

Perhaps concerns over minimum fuel.

You donít squawk 7700 just to get better attention from
ATC on the radio.

Yes, if fuel state was getting to the point of requiring a diversion, and the crew couldn’t get in on the frequency because of all the weather avoiding, 7700 could very well be used to attract the controller’s attention.

But there would have to be an underlying reason?

I'll defer to Heathrow Tower's knowledge here, but I reckon running out of fuel would be a good underlying reason.

Why wouldn't running out of fuel be a reason? At some point, it becomes an emergency.

Some years ago there was a bad crash near JFK when an aircraft in a holding pattern didn't effectively communicate its fuel situation to ATC and ask for immediate clearance to land ahead of some other flights.
