   Instability
   The tendency of an aeroplane to depart involuntarily from the set line of flight. Instability may express itself in yawing (swinging to right or left), rolling or porpoising (following an undulating path). Such faults may arise from a variety of causes, eg insufficient fin area, too short a fuselage, inefficient tailplane, failure to compensate in ...

   Instability
   `Instability` in systems is generally characterized by some of the outputs or internal states growing without bounds. Not all systems that are not stable are unstable; systems can also be marginally stable or exhibit limit cycle behavior. In control theory, a system is unstable if any of the roots of its characteristic equation has real part greater than zero. This is equivalent to any of the eigenvalues of the state matrix having real part grea...

    INSTABILITY
    The state of equilibrium in which a parcel of air when displaced has a tendency to move further away from its original position. It is the condition of the atmosphere when spontaneous convection and severe weather can occur. Air parcels, when displaced vertically, will accelerate upward, often forming cumulus clouds and possibly thunderstorms. Rela...

    Instability
    The tendency for air parcels to accelerate their motion when they are displaced from their original position; especially, the tendency to accelerate upward after being lifted by either topographical features, convergence, or the condensation of water vapour within the air parcel which warms the air.
