departure separation

[offprofile]

Say the runway is 3.5 km long and the only TWYs are at one end and 500 m from the same end, how crazy would it be to have 2 a/c backtracking on the RWY, for departure (provided the first to leave does not need the RWY at full length of course) ?

[Chilli Monster]

No problems at all providing the aircraft behind is always visual with the one in front.

Assuming that both aircraft are on the same rtf frequency, they are told of the departure sequence and position they will depart from, it's daytime, both are visual to the ATCO and that the physical charateristics of the runway do not prevent the second aircraft to depart from seeing the first it would be OK in the UK.

In Denmark, common sense is still applied in some aspects, allthough they are getting fewer every day.

No desk jokey has been clever enough to come up with rules regarding this subject yet, so in CPH it's used all the time regardless of conditions. Common sense then keeps anyone from trying it during LVP.

Unused runway behind an aircraft is wasted runway.....

A double backtrack is a standard procedure in my neck of the woods. Both A/c backtrack full length and take alternate sides of the turning circle, works a treat!

And you STILL getem off in the wrong order

Why would you need to back-track at Copenhagen? Doesn't every runway have full-length taxiways?

[Turn It Off]

Cardiff doesn't have full length taxiway at one end.

Lodnon city doesn't

2 that spring to mind

yes, but some A/C specific turnrestictions forces us to use backtrack.

[Hippy]

Turn It Off: I meant every runway at Copenhagen.

Short Approach?: Thanks for the explanation.
