Carried on over to Air Cadet gliding as well LOL.
P1 grade allowed solo flying without daily solo check.
P2 grade allowed passenger carrying (AEF cadets etc)
Caused much confusion later in life when I returned to gliding in Zimbabwe - when the CFI looked in my old Air Cadet log book he saw the P2 grade glider pilot 'chit' sellotaped on the inside cover and asked why one had a specific qualification to fly as a trainee
The 300 odd launches and 25 hrs TT also caused great mirth
