From the end of the 1960s, civil light aircraft started to use the aerodrome in greater numbers and eventually gained a full operating licence in 1976.

[2] Caernarfon Aerodrome has a Civil Aviation Authority (CAA) Ordinary Licence (Number P866) that allows flights for the public transport of passengers, or for flying instruction as authorised by the licensee (Air Caernarfon Limited).

There is also a helicopter simulator located inside the Caernarfon Airworld Aviation Museum.

The helicopters are leased and are operated on behalf of the charity by Babcock Mission Critical Services Onshore.

At the aerodrome, there is a large café, a maintenance and storage hangar, and a visitor centre and shop which are part of the Aviation Museum at the site.

The technical, administration and hospital areas were on the south side of the runways,[8] along with the air traffic control tower and the watch office.

[13] No.9 (O)AFU continued observer training at RAF Llandwrog until disbandment in June 1945.
