On small corporate jets like the Cirrus Vision Jet, there's no bathroom onboard. Flights typically last under three hours, so the advice is to limit fluids beforehand. If you really need to go, you can divert to the nearest airport or use an emergency urinal bag with absorbent gel.
How do we handle bathroom breaks in the Vision Jet? Well, first of all, we almost never fly longer than 3 hours at a time, so ideally all pilots and passengers can hold it until we land. But when they can't, what do we do?
This is a normal situation on small airplanes. It is an airplane that's very small inside, but you're going between turboprop and jet speeds, and it's tiny inside. It's just like if you're flying on any single-engine or twin-engine airplane, or even a turboprop or a small jet. Very, very limited, if any, toilet available. Usually best to try to go and make sure you don't drink a lot of water when you get on an airplane.
Option number 1, pull over. If absolutely necessary, we can find somewhere to land, find a restroom, and then get back in the air. And option 2, use one of these. This is an emergency urinal, which is basically a plastic bag filled with a diaper-like material that absorbs and turns to gel.
This is incredibly— talking about a real emergency, there's anybody else on the airplane, it's pretty embarrassing. Nobody really would like to do that. It probably smells, and it's not something that you really want to do. You can also pull over. It means, you know, You can descend, land, go to the bathroom, and then get back up in the air. But all of a sudden, that's taken away the whole reason why you're having a corporate aircraft.
