The 737 example is actually quite fitting. Sure, a long time pilot will perceive the interface as invisible. But if you contrast it with the complexity of the same functions on oth…

There is a Bambu p1s on its way to me. I will exclusively print ASA and my impression was that the p1s has a good track record with ASA. My prints will be mounted in glider cockpit…

Since we can't really formally prove most code, I think property based testing such as with hypothesis[1] would make sense. I have not used it yet, but am about to for stuff that r…

Gliders utilize Laminar profiles, while airliners use turbulent profiles. The Laminar profiles perform better, but only when uncontaminated (no bugs or rain). Contaminated turbulen…

Weight affects speed with minimum sink. That affects the diameter of the circle you fly. Since thermals have more lift towards the center (assuming perfectly circular thermals), yo…

The same angle, but at different speeds. The speed is multiplied by the square root of the weight ratio (new/reference). The minimum speed, at which the critical aoa is reached, in…

Glide ratio and weight are not related. Weight shifts the glide Polar to higher speeds and theoretically improves it slightly due to Reynolds effects.

Alan Kay has once said that you get simplicity by choosing a slightly more complicated building block. It appears to me that erlang does this.
