In our theory classes for the PPL we just talked about radio navigation, radarstuff and ATC. Now the instructor mentioned something which got my attention.
Apparently there isn't any ATC-surveillance over open ocean (At least no civil radar coverage). The planes are just assigned slots, meaning that they have to be at a certain point in space at a certain time and that they are assigned a certain speed which they have to use until they are in a ATC-controlled airspace again. This guarantees a certain spacing between the different planes.
As everybody gets told 1000 times on A.net, Boeings generally have a higher optimal cruisespeed than the Buses. So do planes from B have a different Airway than planes from A where all the planes on there fly faster, or does one of them just have to fly with a suboptimal speed? Or does everyone just fly as fast as they want and look out after themselves?
Greetz and thanks for the answers
