Hi Liz,
From what I have been told there have actually been 2 distributions since March this year; one in June (while I was on flight screening actually) and the other was at the same time as the RAAF/RAN distributions on the 20th November. If you want to know when the distributions are going out just call the Pilot selection agency with the details your husband would have received in his FSP joining instructions.
Good luck,
Steve
