This rule is a scam. I have been dispatched under this one time personally. For the hours that are spent teaching new guys this or simply arguing the 20 different opinions people come up , drop the exemption and delay the flight .

I am sure someone will key in and say they get dispatched under it all the time . 5000 hours personally and I rarely rarely rarely rarely see it.

I agree the way Everything Explained for the Professional Pilot does have a great way of sharing his explanation
