I have just pvr'd, on PAS and AFPS 05. PAS did attract a 5 year term to include the AFPS 75 benefits. However, do not get AFPS 05 and PAS mixed up. They are 2 different schemes-PAS for retention-AFPS 05 for reducing pension costs and extending peoples length of service by 2 years(a bit synical I know!).
If you are on PAS and AFPS 05 you do not have a qualifying period for AFPS05 benefits. When you signed up, you immediately became a full member of AFPS 05 and therefore your pension is based on your final pensionable pay and whole number of years served. Your EDP will be based on 50% of your pension (at 65)+1.667% more for each year you serve beyond age 40 or 18. The EDP and pension is index linked from when you start getting it, but you don't recieve increases until age 55. At that point it increases to 75% of your pension + index linked increase. You then get the full pension at 65 + another gratuity of the pension you recieve at 65.
Whether on 05 or 75-it's unique to get a payment at such an early age-unfortunately not enough to keep me in for the next 14 years!
