If you uncheck roll, x, y, z and TrueView in your TR profile, then you will be in 2-axis mode in the game which will use all of your F10 saved views from your hps file for each aircraft. I use that in IL2's to control the gunsight view and bird cage canopy birds to use my saved 6 view. In 2-axis mode your saved look over the hood gunsight view will be your default forward view.
In the very early days of TrackIR it emulated your mouse performing mouse pan view. Thus 2-axis mode.
