For General Aviation (GA), this means that no leisure flying is permitted.
Permitted GA activities
GA flying is permitted for the purposes of work, where it is not reasonably possible to work or provide those services at home. Social distancing measures must be in place and observed at all times.
Flying training organisations providing training for professional pilots, for the purposes of work, may continue to do so. Individuals undertaking such activity may continue to attend for these purposes. Social distancing measures must be in place and observed at all times.
Engine health and maintenance check flights can only take place where there is a critical safety requirement to do so, and alternative options are not available. Such flights, where conducted, must be kept to the minimum duration possible and should land at the same airfield from which they departed, except where this is outside the reasonable control of the pilot.
Whilst these national restrictions are in place, the guidance is to help businesses that are permitted to continue operating to put measures in place to do that safely.
