Recently did a long training cross-country with some of my students... landed at Beaufort West and didn't have any facilities to fax flight plans for our flight to George the next day.
So we tried to file them in the air on the FIR frequency but were told that we can't file it because it is an operational frequency... I was always under the impression that you can file in the air, as long as you do so at least 10 min before entering the airspace...
Can anyone please tell me what the correct procedure is in a case like that?
Cape Town East was very accomodating though and made special arrangements for us... thanks guys
