I believe you are talking about a 6 month PC if I read your post correct. Not sure how you guys do it but this is how GLA does it. No ground for a 6 month PC to be covered, only for a 1 year PC. This is if you are gone for less than 1 year. After that, they make you do ground and flight training no matter what kind of check it was for. For the 6 month, PROBABLY all you can expect is a small amount of requalification training in the sim if you go past your grace period...no big deal. However, you guys may have different training reqs.
