I did not see the flight path symbol on the video, it's like a circle with wings. It's really useful for manual landing, because where it's pointing, it's exactly where you aircraft is going, no matter your speed or flaps setting
I also would like to know more about the HUD. On the 737 PMDG FSX addon, it was one of my favorite features.
How was it implemented on the AEROSOFT CRJ PRO on the P3D?
