I've been following this thread with interest. Stuck in ATR. No idea about your mentality nor does it really matter. But do you understand EASA/JAR rules?
If you position on company business from KTW-LTN-BBU to operate a flight, that time counts as duty. If you are in simulator that counts for duty. If you operate a flight to DTM and back that's duty and FDP.
Allmost ALL company related activities directly in connection with the job including training are duty time for flight crew! The training time needs to be accounted for be it home in front of computer or in a class room. I can understand the reluctance to accept this by you as one might loose a 4 sector day but that's just how rules work, sometimes in your favor sometimes not.
