Exams every two years - bugga that!!
There are a few pilots who know the square root of the pickle but can't open the jar! Try again.
How about CPLs gaining a little more experiance before starting an Instructor rating - say a few hundred hours.
(Howls of protest from production Instructor schools and fresh CPLs with 50NM apron strings)
I only know 2/10's of SFA about the rotary world but I do seem to recall that a level of experiance is needed before a Helo Instructor rating can be attempted.
Have I got the right country/system in mind (I do get confused - bars, aircraft, wives, airports & stories are becoming a blur the older I get)?.
Any of our Helo brethren care to confirm/deny please.
