✈️ Aircraft Stability Lab: Trim, Short-Period, Phugoid, Stall and Centre of Gravity

Fly a generic twin-prop transport and watch static margin, trim elevator, short-period and phugoid eigenvalues, stall and V-n limits respond to centre of gravity, tail size, speed, weight and flaps. Unlike the existing aircraft flight-dynamics sims, this one is built on stability derivatives and eigenvalue analysis (with Lanchester comparison, a lateral-directional tab and a take-off roll estimate), with built-in numerical checks.
