Just a passing thought: Once they go in force, I wonder what effect, if any, the new SIC regs for Part 135 will have on the number of people opting for the CFI route as a time-building means between fresh CPL and 1,500 hours. Not everyone really wants to be a CFI.
Perhaps those aligning themselves with a defined CPL-CFI-regional pipeline will still go that route. But all those not so affiliated ?
