determine whether an airplane is single or multi, land or sea.

Really? I think I'm ready for my government job. Since you're not,
please tell me whether a Seahawker (or Glass Goose) is land or sea.
Be advised, the gear retracts into sponsons, and with the gear
retracted it operates off water. However, with the gear extended it
operates from land.

Or how about a C-185 on amphib floats?
