Enhancement Request: Flight Path Angle / Vector

[fhteagle]

In my opinon, one of the most useful flight instruments out there is the Flight Path Angle and/or Flight Path Vector displays. Flight Path Angle is a display of your current angle of climb or descent, in degrees, shown above or below the horizon. Flight Path Vector is the same display, but with lateral movement to indicate wind drift (difference between ground track and heading). FPA/FPV vs. Pitch indicator is also a "poor man's AOA gauge" that helps you see visually when you are approaching stalling angle of attack.

I would love to see this instrument implemented in this project!

Let me know what I can do to help, especially beta testing.

Thanks.

I love the idea! That should be quite doable using the baro input from the AHRS sensor, along with GPS position info. Alternately (perhaps for pressurized conditions), GPS altitude could be used in lieu of baro altitude.

If GPS track were incorporated as well, a visual display like what is used on the 320 (linked here) should be fairly simple to implement. Would some sort of textual output also be useful?
