I've found teaching I.M.C. an extremely useful skill to have both personally and for the students. You will find the annual I.R. renewal far less daunting and almost all P.P.L's really improve their general hands on flying skills as a result, even when V.F.R.The important thing is to encourage people to simply go out and enjoy flying for fun for a good few hours before they start this,for a low hours pilot,very demanding course.Remember you could be earning when the non I.F.instructors cant!
