The Four Forces of Flight (Lift, Thrust, Drag & Gravity) obey Newton’s Three Laws of Motion. irplane controls work per the Lever Principle, and a wing’s airfoil shape increases lift via the Bernouilli Principle and Coanda Effect. five hours at 150 knots vs. five weeks at 5 knots). The oldest is Archimedes’ Law.

As North American discovered with the Sabreliner, Lear soon realized that the real expense in designing a new aircraft are the hours spent perfecting the airfoils, landing gear, and major systems. Thus, the search for a suitable design led to Switzerland and the orphaned P-16 lightweight fighter project.

We routinely taxi at 1200 rpm due to the low spray…[we] can cruise at 10 knots” in displacement mode, something a Goose can’t do. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance. But it will go 140 knots at 28 gph total.)
