So as a pilot you can't override the software to stop it from "thinking that the plane is on the ground" mode?

Something similar happened recently with A320 when it didn't want to land on an airfield during emergency unless it was flown in a special mode. But F-35 doesn't have that?

"On the ground" = WoW sensors. WoW sensors have been around a long time (see link). And, humans probably should not have any say about that. If humans could override WoW, then the landing gear could be deployed or retracted when it should not and cause a lot of damage due to human error.

Yeah, when I saw that it was related to WoW sensors I was reminded of a chat that I had with an experienced aviation engineer a few years ago when we were considering adding them to the UAS I'm working on. "Every system I've ever worked on that relied on WoW sensors has had some kind of unexpected adverse event due to the sensors either triggering when they weren't supposed to, or not triggering when they should have. If you can figure out a different way to do what you're trying to do, please do."
