๐Ÿ›ซA turn is made by banking the airplane. ๐Ÿ›ซIn any airplane at any airspeed if a constant altitude is maintained during the turn the load factor for a given degree of bank is the same. ๐Ÿ›ซFor any given angle of bank the rate of turn is varies with the airspeed. ๐Ÿ›ซAt given airspeed the load factor increases as AOA increases and the wing stall because the AOA has been increased to a certain angle. ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️ ➡️Do Share with your Friends⬅️

๐Ÿ›ซCeiling refers to the density altitude the aircraft is capable of reaching under a set conditions (configutaion). ๐Ÿ›ซService Ceiling- The service ceiling is the altitude at which the aircraft is unable to climb at a rate greater than 100 feet per minute (fpm). ๐Ÿ›ซAbsolute ceiling, there is no excess of power and only one speed will allow steady, level flight. ✈️Based on Maximum Climb Rate ๐Ÿ›ซAbsolute Ceiling - 0 ft/min RoC ๐Ÿ›ซService Ceiling - 100 ft/min RoC ๐Ÿ›ซCruise Ceiling - 300 ft/min Roc ๐Ÿ›ซCombat Ceiling - 500 ft/min Roc ๐Ÿ›ซRoC- Rate of Climb ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️ ➡️Do Share with your Friends⬅️

๐Ÿ›ซA modern procedure that is widely used is the stabilised approach. ๐Ÿ›ซIn this case, the aeroplane descends from the lowest holding altitude (LHA) in the arrival stack and adopts a 300ft/nm rate of descent that is maintained all the way to the runway threshold. ๐Ÿ›ซThis minimises power adjustments and negates the need for the straight and level segment to intercept the glide path from below. ๐Ÿ›ซIt also reduces fuel burn and although this is not a major saving per flight, when multiplied by the annual total of approached made in an operation, amounts to a significant economy. ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️ ➡️Do Share with your Friends⬅️

๐Ÿ›ซA monocoque structure uses its outer shell to support stresses and loads applied to it, whereas a semi-monocoque structure has an internal "skeleton" of supports and braces to keep its shape rigid and strong. ๐Ÿ›ซThe vast majority of pressurized aircraft are semimonocoque to help distribute stresses equally along the fuselage during flight. ๐Ÿ›ซHowever, some helicopters use monocoque structure to maximize internal space in the flight compartment. ๐Ÿ›ซMonocoque fuselage has its skin holding the skeleton structure together while the semi-monocoque has both the skin and the skeleton holding together. ๐Ÿ›ซSemi-monocoque also has "stringers" running horizontally down the plane to help hold the frame together. ๐Ÿ›ซThe monocoque fuselage also cannot be used for airframes after a certain size (small aircraft with single engine), but the semi-monocoque has been used from single piston engines to commercial airliners. ๐Ÿ›ซA monocoque design would also have

๐Ÿ›ฉ️All aircraft hydraulic systems have one or more power-driven pumps and may have a hand pump as an additional unit when the engine-driven pump is inoperative. ๐Ÿ›ฉ️Power-driven pumps are the primary source of energy and may be either engine driven, electric motor driven, or air driven. ๐Ÿ›ฉ️As a general rule, electrical motor pumps are installed for use in emergencies or during ground operations. ๐Ÿ›ฉ️Some aircraft can deploy a ram air turbine (RAT) to generate hydraulic power. ๐Ÿ›ฉ️Double-action hand pumps produce fluid flow and pressure on each stroke of the handle. ๐Ÿ›ฉ️The double-action hand pump consists essentially of a housing that has a cylinder bore and two ports, a piston, two spring-loaded check valves, and an operating handle. ๐Ÿ›ฉ️An O-ring on the piston seals against leakage between the two chambers of the piston cylinder bore. ๐Ÿ›ฉ️An O-ring in a groove in the end of the pump housing seals against leakage between the piston rod and housing. ๐Ÿ›ฉ️When the piston is

๐Ÿ›ซA sonic boom is the sound associated with the shock waves created whenever an object travelling through the air travels faster than the speed of sound. ๐Ÿ›ซSonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. ๐Ÿ›ซSound travels in the form of wave in all directions. ๐Ÿ›ซImagine that a stationary aircraft has its engine ON , so the sound travels like sphere around the aircraft with each outer lining, representing a wave. ๐Ÿ›ซWhen aircraft moves, the waves ahead of aircraft get compressed, but they do not averlap each other below the speed of sound. ๐Ÿ›ซWhen it travels faster than speed of sound, the aircraft travels faster than these waves and the waves combine to form a single high energy wave called Sonic boom. ๐Ÿ›ซThis forms cone behind the aircraft called "Mach Cone". ๐Ÿ›ซWe can't hear the sound when aircraft passes over is , we can only hear it when the base of this cone reac

๐Ÿ›ซThe Attitude indicator (AL), formerly known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change. ๐Ÿ›ซThe miniature aircraft and horizon bar mimic the relationship of the aircraft relative to the actual horizon. ๐Ÿ›ซIt is a primary instrument for flight in instrument meteorological conditions. ๐Ÿ›ซThe essential components of the AI include a symbolic miniature aircraft mounted so that it appears to be flying relative to the horizon. ๐Ÿ›ซAn adjustment knob, to account for the pilot's line of vision, moves the aircraft up and down to align it against the horizon bar. ๐Ÿ›ซThe top half of the instrument is blue to represent the sky, while the bottom half is brown to represent the ground. ๐Ÿ›ซThe bank index at the top shows the aircraft angle of bank. ๐Ÿ›ซReference lines in the middle indicate

๐Ÿ›ซIn fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. ๐Ÿ›ซA practical application of Bernoulli’s theorem is the Venturi tube, sometimes called a convergent / divergent duct. ๐Ÿ›ซThe Venturi tube has an inlet which narrows to a throat, and an outlet section, relatively longer, which increases in diameter towards the rear. ๐Ÿ›ซThe mass of air entering the tube must exactly equal the mass exiting the tube. ๐Ÿ›ซAt the constriction, the speed must increase to allow the same amount of air to pass in the same amount of time as in all other parts of the tube. ๐Ÿ›ซWhen the air speeds up, the pressure also decreases. ๐Ÿ›ซPast the constriction, the airflow slows and the pressure increases. ๐Ÿ›ซMass Flow is dependent on the ๐€๐ซ๐ž๐š ๐ฑ ๐ƒ๐ž๐ง๐ฌ๐ข๐ญ๐ฒ ๐ฑ ๐•๐ž๐ฅ๐จ๐œ๐ข๐ญ๐ฒ and is a constant. ๐Ÿ›ซThis is known as the ๐‚๐จ๐ง๐ญ๐ข๐ง๐ฎ๐ข

๐Ÿ›ซFlaps are a kind of high-lift device used to increase the lift of an aircraft wing at a given airspeed. ๐Ÿ›ซFlaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. ๐Ÿ›ซFlaps are used for extra lift on takeoff. ๐Ÿ›ซFlaps also cause an increase in drag in mid-flight, so they are retracted when not needed. ๐Ÿ›ซExtending the wing flaps increases the camber or curvature of the wing, raising the maximum lift coefficient or the upper limit to the lift a wing can generate. ๐Ÿ›ซThis allows the aircraft to generate the required lift at a lower speed, reducing the stalling speed of the aircraft, and therefore also the minimum speed at which the aircraft will safely maintain flight. ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️  ➡️Do Share with your Friends⬅️

๐Ÿ›ซThe center of gravity (CG) of an aircraft is the point over which the aircraft would balance. ๐Ÿ›ซIts position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. ๐Ÿ›ซThe center of gravity affects the stability of the aircraft. ๐Ÿ›ซTo ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer. ๐Ÿ›ซCenter of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. ๐Ÿ›ซThe CG limits are indicated in the airplane flight manual. ๐Ÿ›ซThe area between the limits is called the CG range of the aircraft. ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️  ➡️Do Share with your Friends⬅️
