High-flying Twin Otter

Interesting; wonder what it’s doing? This is the Viking series 400 demonstrator.

Twin Otters are not pressurized, are they? I also wonder if it still has the floats on, that’s a good chunk of weight and drag.


Service ceiling is listed as 26,700.

No, it’s on wheels now.

You can of course fly that high with Oxygen tanks/masks. If, for example, you wanted to fly that aircraft in the Himalayas that’s what you’d have to do and that’s possibly what they’re testing.

Understood. It just becomes less practical when you have pax on board.
