Kev - from what I understand, the leans is when your body tells you that the aircraft is doing one thing, when in fact it is actually doing another. Think of VFR flying, when you look out the window, your brain and your vision will match, as you can see out the window. However, when your in cloud, you don't have the vision to rely on and MUST trust your instruments.
Correct! I experienced this during my IMC course, and I think most people do.
All your built in sensors (middle ear etc) with no visual references will tell you that the aircraft is banked left or right (most commonly) or even climbing or descending (less common) but your instruments tell you different!
You HAVE to trust the instruments, and sometimes it ain't easy!
Good luck with the IMC course anyway!
