Notice that FPV is only SECONDARY control!
The primary control is done by the person on the primary controls...the person on the buddy box can control via FPV.
This eliminates any real danger. The aircraft still must remain in sight of the PRIMARY PILOT. I think some people are getting the wrong idea, thinking that someone is controlling an aircraft with FPV and no safety pilot.
Any time the FPV pilot gets too far away or starts to lose control, the primary pilot simply releases the trainer switch and corrects, giving the FPV pilot time to get re-oriented and back on track.
There is NO added danger of flynig FPV as long as the safety pilot has PRIMARY control.
Way to go AMA! I can't wait to give this a try...just have to find a pilot I trust to fly my planes! [8D]
