If Canada were to copy the way flight training is done in the USA where there is no need for all the B.S. requirements for getting and maintaining a FTU it would be possible for older more experienced pilots to make a career of teaching flying.
Conversely if I were to renew my instructors rating it would take months of regurgitating the paint by numbers method that TC requires to be a flight instructor not to mention several thousand dollars for the recurrent training required.
Then once I had my flight instructors rating back I would be at the level of a 250 hour new flight instructor earning potential wise.....and knowledge wise according to TC.
.....now lets see......months of training and thousands of dollars spent......A FTU may pay me two thousand a month before taxes.....
Why don't I jump at that?
