The “Weight of Wing” in aircraft design refers to the mass of the aircraft’s wings, including their supporting structures, control surfaces, and associated components. The weight of the wing is a critical parameter in aircraft design, as it directly affects the aircraft’s overall weight and balance. Here’s the formula, definition, and SI unit for the […]

The “Weight of Airframe” in aircraft design refers to the mass of the aircraft’s main supporting structure, excluding other major components like wings, engines, and landing gear. The airframe includes the fuselage, tail section, and any other structural elements that make up the aircraft’s framework. Here’s the formula, definition, and SI unit for the Weight

The Basic Structure Weight (BSW) in aircraft design refers to the weight of the fundamental structural components of the aircraft, which are essential for its integrity and functionality. These components include the airframe, wings, fuselage, landing gear, and other structural elements. BSW is a critical parameter in aircraft design, as it forms the foundation for

Loiter Fuel in aircraft design refers to the amount of fuel consumed by the aircraft during the loiter phase of a flight. The loiter phase typically involves the aircraft hovering, circling, or maintaining a low-speed, low-altitude flight pattern for a specific mission or task, such as surveillance or reconnaissance. Here’s the formula, definition, and SI

Trip Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and remaining fuel, at the beginning of a flight segment, often referred to as the “trip” segment. It’s an important parameter used for performance calculations and planning for a specific phase of the flight. Here’s the formula, definition, and

Loiter Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and remaining fuel, during the loiter phase of a flight. The loiter phase is when the aircraft hovers or orbits in a specific area, such as for surveillance, reconnaissance, or waiting for a specific task. Here’s the formula, definition,

Climb Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and remaining fuel, during the climb phase of a flight. It’s a significant parameter used for performance calculations during the ascent phase. Here’s the formula, definition, and SI unit for Climb Mass: Formula for Climb Mass: The formula for

Descent Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and remaining fuel, during the descent phase of a flight. It’s a significant parameter used for performance calculations and planning during the descent phase. Here’s the formula, definition, and SI unit for Descent Mass: Formula for Descent Mass: The

Cruise Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and fuel, during the cruise phase of a flight. It’s a key parameter used for performance calculations during this phase. Here’s the formula, definition, and SI unit for Cruise Mass: Formula for Cruise Mass: The formula for calculating cruise

Taxi Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and fuel, at the moment when the aircraft is taxiing on the ground. It’s an important parameter for ground operations and may vary from the takeoff or landing mass due to fuel burn during the flight. Here’s the formula,
