ATC at airports in Class G

[High Wing Drifter]

ShyTorque,

So your terminology COULD then be "G-ABCD, Climbing, altitude 3000 feet", for example.

Or for example: "G-ABCD, ready to climb altitude 3000". It isn't a request, but it gives ATC a chance to tell you that, as far as they are concerned, it is clear.
