Abstract EN
The Routh criterion is used to assess longitudinal dynamic stability of a propeller-driven aircraft.
Under a few plausible assumptions on possible ranges of the pertinent stability derivatives, it reduces to a pair of simple conditions imposing a traditional aft limit (the forward of the maneuver and the neutral-speed-stability points) on the center-of-gravity position and an upper limit on the longitudinal moment of inertia.
It is demonstrated that most aircraft have sufficiently small inertia to remain stable as long as their center-of-gravity is properly placed.
At the same time, sailplane-like aircraft (as, e.g., long endurance UAVs), with an engine installed at the rear extremity of the aircraft, may have sufficiently high inertia to become unstable regardless of their center-of-gravity placement.
