Don't know how much microlight instructors earn, but Porridge is certainly correct to say that conventional FW instructors get screwed.
In reality, what happens is that lowly paid instructors effectively subsidise the PPls' flying training.
Won't never change until we get organised into a Union. Then we can be just like other professionals, charge a decent rate in the knowledge that the guy next door won't undercut us. Solicitors do it, why can't we?
Alternatively, the employment laws may come to our aid. As some of you may know, the Inland Revenue is assessing the status of "so-called" self-employed flying instructors. A decision has not been reached, as yet, but I hear rumours that there is a call for us to be given the protection of the law and made employees.
If we attain a proper status as employees, we may then dare to raise our heads above the parapet and organise ourselves into an effective professional body.
