OPC periods.
According to JAR-OPS you are required to do your OPC with 6 months periods, and you can do them up to 3 months before your expiry date, but is there a limit as to how close they can be?
I have a memory of reading somewhere that your OPCs has to be at least 4 months apart from eachother, but I can't seem to find it anywhere in JAR-OPS now that I look.
To examplify, if your periods are May/November, and you did your last OPC November 30th, do you have to wait until the 1st of April for the OPC to get the same date, or can you do it as early as the 1st of March?
Thanks for any help on this one.
