Is this new facility near the old one?
Will have to help out here! A good callsign could be "Eh Pure Control" with translation lessons being started early:
Go it yeerseelf, big chap = Resume own navigation
Oan yer bike = Cleared for takeoff
Naw yer gawn eh wrong way = Turn right 10 degrees, report new heading
Hawd yer weisht = Radio silence please
F'k ye dain = Report your speed
Gees a clue = Squaw Ident
Am fair scunnered, big chap = Radar services terminated
Aye atsrite = Readback correct
Hauld it right there = Break
= Correction
Jist his wance mare = I say again
Geez yer patter = Pass your message
Wit wir ye toalt?! = Require a readback
Hauld it im droonin = Standby
Spoatoan = Affirm
Confirm? = Ye sh&ttin me pal?
Anymore suggestions?
