This is ridiculous. Part of the purpose of the NPRM is to not separate carriers. Pilots are Pilots. Flying is Flying. When the door is closed and you are at the controls it doesn't matter if the flight release says scheduled or unscheduled. The previous airline I worked for (unscheduled passenger charter) had management who was crying wolf to congress that they would have to shut down their operation and blah blah blah if the NPRM is passed. It seemed that almost weekly they were headed to DC to complain. The NPRM needs to be ONE for ALL and absolutely little to no exemptions to the rules should be handed out to any airline with regards to rest requirements. Don't get me wrong, I think there are several improvements that need to be made to the NPRM, but it is better than what is currently in place.
