Instead of binding my TrackIR's "Z" axis (forwards and backwards - towards/away from screen) to move my head forward an backward inside the cockpit, i've assigned it to "Zoom View". So if i lean towards the instrument panel, and slightly over to the side of the MFCD i'm looking at, i can fill my monitor with the MFCD screen, and i can come away from it, returning to a normal view, just by sitting back in my chair again.
