Difference Between Static Stability and Dynamic Stability

Static Stability

Static Stability vs Dynamic Stability   Generally the stability of an aircraft is defined as the aircraft’s ability to sustain a specific, prescribed flight condition. The concept of stability is closely related to the equilibrium of the aircraft. If the net forces and moments exerted on the aircraft is zero, the aircraft is in equilibrium, […]

Difference Between Subsonic and Supersonic

Subsonic vs Supersonic   The velocity of the air flow plays a critical role in determining the characteristic of air flow. Air flowing at low speeds can be considered as a viscous fluid with incompressible properties, like water. When the velocity of the air flow increases, the properties related to the compressibility change significantly resulting […]

Difference Between Flaps and Ailerons

Flaps vs Ailerons   Any aircraft is controlled mainly by the moveable surfaces fixed at the edges of the aircraft wings. Changing the position of any surface creates an unbalanced force or a couple around the center of the gravity of the aircraft and aircraft moves accordingly. There are two important moveable surfaces mounted on […]

Difference Between Airbus A380 and Boeing 747

Airbus A380 vs Boeing 747   In their race for dominance in the commercial airliner market, Boeing and Airbus produced two very large aircrafts, revolutionizing the commercial aviation. They are able to carry more than 400 passenger and able to fly Trans-Atlantic without refueling. The development costs are enormous (six billion dollars for A380) both […]

Difference Between Airbus A380 and Boeing 787 Dreamliner

Airbus A380 vs Boeing 787 Dreamliner   The Airbus A380 and the Boeing 787 Dreamliner are the newest commercial aircrafts designed and built by Airbus (EU) and Boeing (USA). Airbus A380 was introduced to commercial aviation with Singapore Airlines in October 2007, and the Boeing 787 made its first commercial flight in October 2011 with […]

Difference Between Airbus A380 and Boeing 747

Airbus A380 vs Boeing 747 Airbus A380 and Boeing 747 differ in a number of features. The most popular feature in Airbus A380 is the double deck all along the plane whereas Boeing 747 is not characterized by such feature. Airbus A380 is considered a real revolution by itself, it is the largest commercial aircraft […]
