What Makes an Aircraft Stable? | Aerodynamics in X-Plane 11 (3/4)
The X-Plane 11 flight simulator is an awesome tool to explore concepts in aerodynamics like stability, which are super important in aerospace engineering. Static stability can mean the difference between a controllable aircraft and one that will almost inevitably crash. Let's see why this 747 falls out of the sky.
8:44, this should be the other way around (Cma = Delta T / Delta alpha). For Cma = 0, a change in angle of attack will cause a zero change in torque, meaning that the aircraft is neutrally stable.
