The bottle neck is the runways at the airport. That's why Heathrow
wants
to build a new one.

Not all planes fly to heathrow.


Allowing free choice of routes is for fuel savings.

No it isn't.


The economical
cruise altitude rises as the plane gets lighter, so they want to
climb
gently all the way across the ocean.

But they don't do that.
They don't take the shortest route from A-B they take a route
where they can be tracked.
Friend flew from gatwick to cacun on tuesday explan why they didn't
just fly directly across the ocean


Great circle

Largely it takes you over greenland labrador and down the E coast of
the USA

Why doesn't it just go across directly then that would be a shorter
distance less fuel quicker flight ?

That is the shortest distance. That is going across directly.




It could go across cornwall but it doesn't it heads North to greenland.


Buy yourself a globe and a bit of string and measure it

look at the real info that I have linked to.

It says nothing useful about what is being discussed,
what happens in the middle of the ****ing ocean etc
with no airport anywhere near and no radar coverage.

The majority of air traffic contols stations DO NOT use GPS.

Irrelevant to what ACARS uses.

Not knowing where a plane is and at what
height isn't the best way to 'control air traffic'

Even sillier than you usually manage in the
middle of the ****ing ocean outside radar range.

In the future when the majority of ATC
can use GPS then things will change

Not with routes over the ****ing ocean it wont.

and yuo do know that with GPS the ATC building doesn't even
have to be located at the airport it can be almost anywhere.

Its DISPLAYING the GPS information and
yes, the controllers and be anywhere at all.
