Abstract
The inherent quality of an airplane to correct its balance and return to the original horizontal alignment after suffering any disturbance is called stability. The stability of an aircraft is a decisive factor for its design and commercial success, because a single disturbance can lead to misalignment that in turn can lead to time and fuel waste, damages, and in worst case disaster. The most common method to achieve stability is the alignment of the plane horizontal axis with the horizon line that can be done by onboard digital or mechanical systems, or even with a human manual control. Systems that ensure flight stability are a crucial part of an aircraft machinery and also expensive and maintenance costly. The present paper propose the development of a simpler and cheaper control and command system to detect and respond on time when an aircraft’s alignment is off. A model aircraft was tested in a Wind Tunnel with a simple Arduino circuitry board, a digital gyroscope, and a set of servomotors as an onboard PID system that can optimize flight control and ensure stability. This method does not just provide an objective and in-depth assessment of flight stability, but it also provides a low-cost alternative to the expensive control and command systems currently in use.
