C'mon Bose ...
If you are in IFR airspace and not training for IFR skills then I have to ask why any responsible Instructor would be trying to teach VFR skills in IFR?
How about because the only clear weather is in an area of airspace where flight under IFR is the best choice. How about my scenario of operating less than 1,000' below the cloudbase?
BTW, what's "IFR airspace"?? As I understand it IFR is a set of flight rules which a pilot can choose to operate under, he may make this choice while flying in any class of airspace he likes.
As instructor I believe it is incumbent upon us to be precise in our use of the technical language associated with aviation and not, for example to say IFR" when we mean "IMC", not to say "sideslip" when we mean "drift", not to say "bank" when we mean "roll", not to say "power" when we mean "thrust" etc etc. It's confusing enough without the experts muddying the waters still further.
