As a student I was checked out by a then flying inspector from DCA not to find out my form but to check the instructors
As A CFI one only had to fly with a instructors pupils to determine not only his ability and more importantly his approach to the job.
DCA's approach to flying schools inspection feel away when a certain hospital fitted became the chief flying inspector. As a civil servant it was taboo to work over the weekend when most of flying training takes place. To raise the standard it is doubtful whether 4 throttles or ALTP's will help regulate visits by current Flying Inspectors is what is required
