Two things:
1. In the DJI Pilot app go to camera settings and select Smart Arm LEDs...This should make the M2E go ‘dark’... you might as will have to check the settings for the bottom LED because if you get too low it could turn the ‘landing light’ on.
2. Just sayin’ - It should be a Part 107 flight with all the necessary waivers, as the presumption is a)this is at night, and b) the pilot (and/or visual observer)cannot maintain VLOS to determine distance, altitude or orientation of the sUAS by the unaided eye. Their night waiver needs to state this and how they will mitigate these risks.
This would not just be a ‘standard’ night waiver, as you typically have to run a strobe or other marker lights on the aircraft that allow you to see it at 3 statute miles.
That just gave me a brainstorm; the visual observer could have night vision on and you put a IR marker light on the M2E (hehe)...
