Hi
How about Control Input Indicator option for planes?
You could see recording plane primary inputs (pitch, roll, ya & throttle) from film playback if wanted.
The secondary inputs (flaps, trims, rpm & gear) could be a second option.
IMHO a very good tool for analysis and training. How to perform maneuvers control input wise.
You can see yellow control Input Indicator on these pictures from Flanker Su-27 ver. 1.5.
What you think?
