This will or so they think will enable them to
fly more planes as theere can be more routes.

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.

Heathrow is the one with fewer runways than it needs for the traffic
volume.

They were plans to add runways to other airports or to build a new London
airlort.

Irrelevant to the fact that Heathrow only has two parallel runways
and that its by far the highest volume airport in Britain.

London has more than one airport, if yuo added runways to gatwick or standsted then it might be that heathrow wouldn't have the highest volume in Britain that;s the point spread the laod out not just pile into 1 or 2 airports.



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.

True, but thats for other reasons.

Yes because they donl;t like losing radar contact with planes,

Thats a lie with the long haul flights over the ocean. There is no
alternative.

they are in the minority presently.



Didnlt find Malaysia Airlines Flight 370 did it.

Because they chose to turn theirs off to save on the cost.

So how comes they couldn't use radar to find where the plane was ?




Friend flew from gatwick to cacun on tuesday explan
why they didn't just fly directly across the ocean

Because the system is moving to the new system which
allows all ACARS equipped aircraft to be tracked anywhere.

Sure a systemn from 1978, being replaced by GPS.

ACARS isnt being replaced by GPS.

It will be replaced as ACARS isn;t in real time and can be turned off.
It is going to be replaced where they use the 'internet' rather than radio.
