Ball park salary is around £20-22000 pa and up at start, hourly rate for part time is around £50 per flying hour, once experienced expect 26000 - 40000.
When you consider you need 30 hours P1 MEP (p1s does not count) to start the MEP teaching course and a couple of grand for both the IR and the twin teaching courses it is a very poor salary, better off financially driving a bus! but not as fun.....There will be no bond if you pay for the courses and hours yourself or tell them to get stuffed if they try to bond you!
