The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX) The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1]
The radius of action of an aircraft is always smaller than its maximum range, the furthest distance the aircraft can fly with maximum payload and without refueling, or ferry range, the furthest distance the aircraft can fly with drop tanks, no load or ordnance and without refueling. The rule of thumb is that the radius of action is one-third ...
Fuel fraction is a key parameter in determining an aircraft's range, the distance it can fly without refueling. Breguet ’s aircraft range equation describes the relationship of range with airspeed , lift-to-drag ratio , specific fuel consumption , and the part of the total fuel fraction available for cruise, also known as the cruise fuel ...
Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft.. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air.
The maximum endurance condition would be obtained at the point of minimum power required since this would require the lowest fuel flow to keep the airplane in steady, level flight. Maximum range condition would occur where the ratio of speed to power required is greatest. The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX).
Best range speed – the speed that gives the greatest range for fuel consumed – often identical to V md. [35] V FS: Final segment of a departure with one powerplant failed. [36] V imd: Minimum drag [37] V imp: Minimum power [37] V LLO: Maximum landing light operating speed – for aircraft with retractable landing lights. [9] V LS: Lowest ...
The area between the limits is called the CG range of the aircraft. Weight and Balance When the weight of the aircraft is at or below the allowable limit(s) for its configuration (parked, ground movement, take-off, landing, etc.) and its center of gravity is within the allowable range, and both will remain so for the duration of the flight, the ...
Stability and control derivatives change as flight conditions change. The collection of stability and control derivatives as they change over a range of flight conditions is called an aero model. Aero models are used in engineering flight simulators to analyze stability, and in real-time flight simulators for training and entertainment.
