I believe it says in my initial (admittedly not all that thrilling) spiel; you don't really need an IR and some might say that it isn't even considered an advantage since you won't be doing any IMC work. If I go out there I will have one, so it will probably lapse and I'll have to go through the emotional prospect of another IR skills test when I come back. Joy.
Five hours in a c206 is a definite tickage in the box though.
