| PA-2 scans for light variations between the ground and the sky. It basically looks for the horizon. Thus it will not work at low heights. I don't know if there are any other reasons apart from that.
FMA co-pilot is said to be much better and I have already ordered one. waiting for it to arrive. I think FMA works in a similar manner to PA-2 but looks for infrared radiation rather than daylight. Thus it will probably also need an open field to work. |
