I have no idea how, but my smartwatch touchscreen remains responsive underwater, in a bathtub or swimming pool. It was with on every workout, and it both endured the energetic movements and sweaty hands were not an issue. The thing has more RAM and CPU power than my desktop in first half of the 90s, runs Linux, and is programmed with JS (well, there's gotta be some faulty part in every design). Anyway, if I can buy such a thing for a few hundred dollars, then - unless there are some physical limitations I'm not aware of - it should be possible for people who build the planes.
