| The kinds of planes you're thinking about, yes. From what I understand, it's affected by two things: 1. The regulatory side, driven by the size and complexity of the plane. That in turn affects potential number of passengers and typical hiring arrangement (pay-per-seat vs charter vs personal use). If you google best single-pilot aircraft, you'll see things like the hondajet, pilatus pc-24, and citation cj2/3/4. Nothing larger or more complex than that. 2. Insurance requirements for particular flights. If you're hiring out a plane to carry other people, you need a different kind of liability insurance. That insurance might require you to have two pilots even for a small plane (like a stereotypical primitive prop plane, or a previously mentioned small jet like hondajet or citation cj2/3/4) that might in other situations be legal to fly with a single pilot. Or, for someone like an executive with hefty personal injury insurance, that person's insurance might not cover them if they fly in a plane with a single pilot. That's not to say that all "for hire" flying requires two pilots. Consider small prop planes for sightseeing, or skydiving, or island hopping the Caribbean. Unless something's changed recently, you won't have two pilots for those kinds of flights. The reason I brought up personal insurance for passengers: CitationMax (certified ATP pilot who flies his parents around in their private jet) on youtube has mentioned that his father's personal/executive insurance requires him to fly with two pilots. Even when they had a cj3+, they added a contract pilot when his father was onboard. Now they have a citation longitude, which is large/complex enough that it can never be flown with only one pilot, even if no passengers are onboard. |
