So, it’s the front sensors that are triggering the obstacle? Do you get the corresponding arc In Go4? What time of day did it occurr i.e., was the sun high or low? I never saw this on my MP and haven’t seen it on the
M2P either despite the fact that there’s lots of sun down here in South Texas. It’s pretty much gotta be infrared, don’t you think?
While flying Kingairs in the Navy teaching students, the PT6 engines had a notorious fault whereby sunlight coming through cracks in the cowling could trigger the infrared fire detection system. This sounds mighty similar.
