And Automatic Control Nelson Solutions: Flight Stability

An aircraft has a lateral stability derivative of -0.1 and a directional stability derivative of -0.2. Determine the aircraft's lateral and directional stability.

For directional stability, the following condition must be satisfied: Flight Stability And Automatic Control Nelson Solutions
