Applications here are very straight forward. Send through your documents along with your permit request to the CAA direct. They’ll also require a copy of your security manual. Keep in mind the CAA work on weekdays so if you are looking to get a permit at the weekend you’ll need the assistance of an agent.
Give 24hrs notice for Tech and Private flights. Commercial flights need 3 days notice for a one-off flight and 2 months if you want to carry out a series of flights.
