What is aircraft stability and control?
The term stability characterizes the motion of an aeroplane when returning to its equilibrium position after it has been disturbed from it without the pilot taking action. Aircraft control describes the response to actions taken by a pilot to induce and maintain a state of equilibrium or to execute manoeuvres.
What is aircraft stability?
Stability is an aircraft’s ability to maintain/return to its original flight path. Allows aircraft to maintain uniform flight conditions, recover from disturbances, and minimize pilot workload.
Why is stability and control important to aircraft?
An aircraft must have sufficient stability to maintain a uniform flightpath and recover from the various upsetting forces. Also, to achieve the best performance, the aircraft must have the proper response to the movement of the controls.
What are the factors of in flight stability?
Factors affecting longitudinal stability:
- Horizontal stabilizer.
- Center of Gravity (C of G)
- Center of Pressure (C of P)
- Propeller position (puller or pusher prop)
- Power Setting.
- Short fuselage decrease stability.
How are aircraft Stabilised?
At the rear of the fuselage of most aircraft one finds a horizontal stabilizer and an elevator. The stabilizer is a fixed wing section whose job is to provide stability for the aircraft, to keep it flying straight. The horizontal stabilizer prevents up-and-down, or pitching, motion of the aircraft nose.
What are the condition of stability?
The essence of stability condition is that the error introduced into the approximate solution by a particular difference method remains uniformly bounded as nāā with n as the solution time step.
What is the 3 factors of in flight stability?

What are the four forces of an airplane?
These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
What is stable approach?
A stabilized approach is one in which the pilot establishes and maintains a constant angle glidepath towards a predetermined point on the landing runway. It is based on the pilot’s judgment of certain visual clues, and depends on the maintenance of a constant final descent airspeed and configuration.
What is control in aviation?
Description. Aircraft flight controls are the means by which a pilot controls the direction and attitude of an aircraft in flight. Flight control systems are subdivided into what are referred to as primary and secondary flight controls.
What are the factors that affect stability?
Common factors that affect this stability include temperature, light, pH, oxidation and enzymatic degradation. Special considerations are also required when dealing with chiral molecules, deuterated internal standards and large biomolecules.
Why is stability important in control system?
System stability is one of the most important performance specification of a control system. A system is considered unstable if it does not return to its initial position but continues to oscillate after it is subjected to any change in input or is subjected to undesirable disturbance.
