Sorry. I was responding to the coaching from the sim after I completed. It said something like, “failed to use landing lights in a nighttime flight”. I’m not a pilot so I’m not familiar with real world requirements but to clarify my report, I’d say there was maybe only one issue: Based on what you said, then the language of the coaching should say, “failed to use landing lights below 10,000 feet.” The night flight thing was a red herring. It was my first career mission flight, it was supposed to be a daytime flight and it was daytime so the sim got that correct. I was thrown off by the coaching after I got dinged.
