Regardless of what's on the ground, they routinely start to turn very
soon after take-off, so as to head in the direction they need to fly
(ie, to join the airway). It's not normally straight ahead.

I used to live in Reading which is almost exactly due west of
Heathrow. Tell me again about the planes having turned off before then.

A few head west over Reading, but others turn over Windsor. It depends
where they are going.

So some do go straight ahead, contrary to what you said before.

In addition some of those that do turn will be turning north-west across
London, it's a big place.


But there's no need to argue about this, actual data he

I've just watched a Heathrow-Edinburgh flight take off west and turn
right over Cookham heading for High Wycombe then Bedford;

Extrapolate that to a take off east of London and what route will it take?

and a
Barcelona flight skirting the east edge of Windsor Great Park on the way
to Guildford.


A fun site that. There's a Virgin flight to Barbados passing over me at
the moment.
