The last page is really where the meat of the stuff concerning pilot's wanting to get on with a 121 op are (sec 216 + 217). I wonder how candidates for an ATP will be examined for functioning in a "multi-pilot environment" and "highest professional standards."
Also wonder how many multi-engine hours will be required, as well as those hours of "Difficult operational conditions." 1,500 hours TT, 500ME, 100 Actual and 50 Icing conditions, of which 10 have to be at night? Unless you rent a Barron and fly it in the winter time, I wonder how people are going to get "difficult operational conditions." Could time spent in training for an airline be applied to those conditions if they were in the simulator?

Is this is possible avenue: Person has 1500 hours, applies to Regional X, and passes interview, although s/he doesn't have the extra requirements for the ATP. During training for that vaulted SIC type rating, they get training in multi-pilot environment, high altitude, icing conditions and "professional standards." At the end of training, they get their SIC type and also take a checkride for ATP. Or do you folks think an ATP would required to even apply?
