Independent Parallel Runway Spacing

[Daysleeper]

Can anyone point out where I can find info on how far apart runways have to be for independent ops in the UK. Cheers

I am looking for the same, also where can I find ICAO airport stds.

thks for any help

It should be in ICAO Doc 9157, but which part i'm not sure!

Independent as in no vortex considerations?

I think it's 760m.

[cdb]

Agreed - 760m for vortex purposes. 3nm separation still needs to be mantained between IFR flights though!

[Daysleeper]

Independent as in capable of simultaneous operation so parallel approaches or take offs etc.

[Gonzo]

To be completely independent, 3 miles.

Of course, you can do simultaneous parallel approaches and departures on runways closer than 3 miles apart, but only with visual separation.

We do parallel apps and deps all the time and in any weather.
Both rwys operate independently always here in Munich.
They are 2300m apart.

I believe there has to be at least 1525m between to parallel RWY's for independent operation. With less than 1525m but more than 915m one will have the usual spacing of 3 miles, but in addition 2 miles spacing between traffic on the two approaches.

Thanks for all the help so far, has anyone got a specific ref? I need to be able to say definitavely
"according to xyz the runway needs to be xxx meters apart"

I've had a look in CAP 168 but to no avail.
