Have fly tippers been busy or something? What do you mean a hill?

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.

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.

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.

William the Conqueror found it convenient for the airport.

The runway is definitely not level.

That was my first posting to the thread, so no I didn't say anything
before.

across London, it's a big place.

What's important here is how far west of Heathrow they get, so we can
compare how far west of the estuary airport the planes might turn.

There's a flight to Los Angeles coming over Notts soon, and that stayed
within 5Km of the end of the runway (measuring east-west; it flew just
east of High Wycombe).

No further west than the M25. There's an air lane over Maidstone,
Harlow, Corby, Nottingham with loads of transatlantic flights from
continental Europe currently.

It's so that you get that great view of it when you walk through the
gates of Legoland.

What utter ********. The quicker they can get to altitude the better
from a fuel usage point of view, but they are usually climbing most of
the time during a departure, that they have to fairly rapidly change
their heading two or three times in a pre determined sequence is
irrelevant to overall fuel burn.

That's got immediate environmental costs, will add to
operating costs and could make the airport unattractive for airlines
operating the very long-haul routes (Japan, Australia..).

It's no different to departures at many airports worldwide, you don't
just take off and carry on in the same direction to your destination.

You also really don't want to be manoevering at maximum weight and have
an engine ingest a goose. That could lead to substantial stress in the
cockpit.

Better drain those reservoirs near Heathrow then.

These are a bit out of date but show the standard instrument
departures from Heathrow.

A United flight from Paris to Chicago has just flown over my house, and
I mean *right* over - on the mapping site it was within one house width.
