Turbine pic would be great but completely unrealistic. 1500hr is not perfect but it is realistic. The goal is to raise safety and 1500hr dose it!!!
1500hrs of 172 instruction? Not at all. Pilots need experience in weather navigation, ATC interaction, high altitude aerodynamics, complex systems integration, high density airport operations, PIC decision making, department management, weather depiction, etc. Not 1500hrs of lazy 8's and shooting NDB approaches.
