I agree with the fact that they will not allow pilots to test on light twins. 1500 hrs of instruction time only means that on paper you have got the hrs required. In terms of operation of aircraft in the 121/135 cat. a person with 1500hrs bombing around a cicuit in a c182/PA34 has no experience to render him capable of commanding an aircraft above 5700kgs, purely because he has an ATP!!! That ATP means nothing,excepting on Paper. When I started flying contract. I flew with one to many captains who had command on the aircraft because they had an 'ATP', 90% of the experience behind them consisted of flying C150/C172's in the circuit. THIS IS DANGEROUS!!!!!!!! The new regs thankfully end this problem, Well done SA, a step in the right direction.
