Flight Stability - Essay Example The most important flight management and control information is based on stability principles that are mainly referred to as static and dynamic principles. Considerations of the stability elements as highlighted in the section below are useful in the formulation of appropriate stability systems in aeroplanes. A balanced position of an aeroplane in flight is termed as a trimmed position in terms of stability, which is affected by introduction of static instability forces. Static stability is the capacity of an aeroplane experiencing static disturbance to revert to its trimmed state. An aeroplane is deemed to be in stability if there are no changes of acceleration towards a particular axis when in flight. When the aeroplane is exposed to static forces of disturbance, instability is experienced and the ability of the aeroplane to return to the static condition is determined by its capacity to overcome the disturbance and achieve the earlier stability (Ly 1997, p23). In the trimmed state, the aeroplane is generally in a stable condition that does not require extra input in order for it to be sustained in the condition. The aeroplane must be installed with systems to assist it revert to the steady state after a disturbance, which creates a disorientation of the stable axis conditions. Along the longitudinal axis, the appropriate conditions are achieved by introducing elevator trim tabs which are engaged until the previous static condition is achieved (Pamadi, 1998). This is achieved by the aeroplane system where the input of the pilot is not needed because it is on a hands-free operation installed in the design of the aeroplane. To assist in the detection of the instability of the aeroplane after a static disturbance, there are two types of analyses systems that can be used in such systems. On one hand, there is the stick-fixed manoeuvre which detects disturbance and maintains the same position in response while stick-free system is designed to
