When you have 100hrs, you think you know it all.
When you have 500hrs, you KNOW you know it all.
When you have 1000hrs, you know you'll never know it all.
Sorry, I'm not going go back and quote people by name but admitions have been made regarding what people got up to when they were newly qualified and giving the best instruction they are capable of. Good points.
An hour-building 'professional' may be able to pass on the required knowledge for a student to get a PPL but to be a 'pilot'.No.
There are Drivers, Pilots and Artists.
There are even instructors who have never even flown a taildragger. Can you believe that? Never flown a taildragger!
There are top-class aerobatic competition pilots who are not CPL holders.
Are people suggesting that they aren't actually very good pilots?
After all, they are only PPL's.
