Hi author here, I have worked in the aerospace industry on flight control systems. I'm very familiar with knots as a unit. I'm just annoyed that so many educational resources and even flight code still use customary units for everything. I believe that metric should be used for all internal calculations and knots should only exist at the UI layer for the pilot. When I play flight games though, I only have intuition for speed in terms of knots. Like 150 kts is takeoff speed and 400 kts is the corner speed. I just think that the pilot letting out a spool of knotted rope from their plane is a very silly practice to defend :)
