The reason for the high failure rate on the 330 is the large number of unsuitable weak candidates being put forward for command. i am sure if the line captains were asked to name who would struggle it would be the same names over and over again. This is where the seniority system becomes a problem as many of the high quality pilots are sitting in the right seat because all the training is being wasted on people who should never be considered for command.
I for one will also welcome any DEC on the 330 who will be able to reduce the workload, however its a shame for the many competent guys who will probably have their upgrades delayed.
The answer has to be a tightening up of the selection criteria and looking beyond if a guy can pass his PPC using the secret instructor notes.
