at the end of the day an IR is an IR, it shouldn't matter what you do it in all that matters at the end of the day (half an hour after sunset) is how good you are at it i would have thought
Nah, not really.
An IR is ALL about systems management and planning.
The two go together and if you learnt in an aircraft where the systems were looking after you, the systems management becomes CONSIDERABLY different than when you get chucked into an 30+ yr old Aztec where the ADF has to be tuned and the DI and VOR are split.
Not to mention having an autopilot that only works on Sunday.
