Charlie 1 is our designated training airspace. Flights are allowed any time during daytime between 0 and 800ft AGL (we advice however not to fly below 300ft AGL).
Charlie 2 to 4 can also be used without lodging a flight plan, however Clark airtraffic control should be informed by radio.
See the How to guides on how to make a radio call.
