「Request frequency change」is, when do you use?
A little while ago, when i take off the WMKK of Expert server. when I request a 「Request Frequency Change」, it was said to “check the help page.”
Is it my mistake?
I at that time, it was just before leaving from the Airspace.
“Request Frequency Chnge” is, do you use when you leave the airspace?
I thought that to use away from the Airspace.
My English is poor, but please tell me.
