My replacement pilots in the experimental CHS version have been proving to be merely Tony bait...
That -is- a VERY annoying issue that I've found with CHS. At least in #156, the exp level of (at least) USAAF pilots does NOT increase over time. They start the game at 50, and even 1943, I'm still pulling USAAF pilots with 45 - 55 exp. Of course, I didn't realize this the first time I sent out out a newly upgraded squadron of P-38s (with many replacement pilots, I didn't think to check their exp). Needless to say, their combat debut was a disaster. So now I make sure I'm only upgrading the most experienced squadrons, and try to train whenever possible.
In the experimental CHS scenario that we are playing, the USAAF replacement pilots have an average rating of 45, which means that I've received pilots into my squadrons with ratings as low as 35. I am definitely being careful about which units upgrade first, and have been using the "training" function quite heavily.
