🛫A turn is made by banking the airplane. 🛫In 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. 🛫For any given angle of bank the rate of turn is varies with the airspeed. 🛫At 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⬅️

🛫Ceiling refers to the density altitude the aircraft is capable of reaching under a set conditions (configutaion). 🛫Service 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). 🛫Absolute ceiling, there is no excess of power and only one speed will allow steady, level flight. ✈️Based on Maximum Climb Rate 🛫Absolute Ceiling - 0 ft/min RoC 🛫Service Ceiling - 100 ft/min RoC 🛫Cruise Ceiling - 300 ft/min Roc 🛫Combat Ceiling - 500 ft/min Roc 🛫RoC- Rate of Climb ➡️Subscribe us for more aircraft knowledge and aircraft fact⬅️ ➡️Do Share with your Friends⬅️

🛫A modern procedure that is widely used is the stabilised approach. 🛫In 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. 🛫This minimises power adjustments and negates the need for the straight and level segment to intercept the glide path from below. 🛫It 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⬅️

🛫A 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. 🛫The vast majority of pressurized aircraft are semimonocoque to help distribute stresses equally along the fuselage during flight. 🛫However, some helicopters use monocoque structure to maximize internal space in the flight compartment. 🛫Monocoque fuselage has its skin holding the skeleton structure together while the semi-monocoque has both the skin and the skeleton holding together. 🛫Semi-monocoque also has "stringers" running horizontally down the plane to help hold the frame together. 🛫The 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. 🛫A monocoque design would also have ...

🛩️All 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. 🛩️Power-driven pumps are the primary source of energy and may be either engine driven, electric motor driven, or air driven. 🛩️As a general rule, electrical motor pumps are installed for use in emergencies or during ground operations. 🛩️Some aircraft can deploy a ram air turbine (RAT) to generate hydraulic power. 🛩️Double-action hand pumps produce fluid flow and pressure on each stroke of the handle. 🛩️The 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. 🛩️An O-ring on the piston seals against leakage between the two chambers of the piston cylinder bore. 🛩️An O-ring in a groove in the end of the pump housing seals against leakage between the piston rod and housing. 🛩️When the piston is...

🛫A 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. 🛫Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. 🛫Sound travels in the form of wave in all directions. 🛫Imagine that a stationary aircraft has its engine ON , so the sound travels like sphere around the aircraft with each outer lining, representing a wave. 🛫When aircraft moves, the waves ahead of aircraft get compressed, but they do not averlap each other below the speed of sound. 🛫When 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. 🛫This forms cone behind the aircraft called "Mach Cone". 🛫We can't hear the sound when aircraft passes over is , we can only hear it when the base of this cone reac...
