Comparing night flights to daily flights, the night flights were, on average, 26 seconds or 10% longer than the day flights. This was due to an extra 43 seconds spent on target at night. The pilots reported not being able to see the drop zone target until they were close to the ground while flying at night. Interestingly, the speeds to target and back to base were faster at night. This may be explained by pilots not being able to judge their speed against the stationary terrain which they cannot see at night. In ​ DroneUp ​ ’s training of pilots new to night operations, flying faster than usual has been consistently observed. We suspect this demonstrates a general weakness in instrument proficiency, which is required at night when there are fewer visual cues.

Test 7 Results

Test 7 was one flight conceived by the CEO of ​ DroneUp ​ to be an extremely difficult challenge. It was night. It was in extremely tight spaces with multiple obstacles. The VO was a layperson on a cell phone and there was an imposed deadline due to the scenario of delivering snake antivenom to a clinic under quarantine. The Blue team executed Test 7 with flying colors. The layperson, a Brunswick County Deputy Sheriff, was escorted to a building and told it was a clinic and he had to direct an incoming drone that was delivering snake antivenom and it had to be there within 10 minutes. Aided by his public safety background, the LoadMaster was able to direct the Deputy to shine his flashlight first up in the air to locate the clinic and then down on the landing spot to provide
