contacting ATSU

[eddiet]

hi there,

have a noob question here.

When a pilot is in contact with an ATSU, how long should he wait for a reply before repeating his transmission?

[HEATHROW DIRECTOR]

He shouldn't have to wait but, inevitably, in busy sectors he might have to call again. If it's a quiet frequency I would say 20 seconds at most.
