20 Interesting Aviation Facts You Probably Didn't Know

头 20 父 interesting facts about AVIATION A Boeing 737 weighing 150,000 pounds (68,000 kg) must deflect about 88,000 pounds (40,000 kg) of air - over a million cubic feet (31.500 cubit metres) down by 55 feet (16.75 m) each second whilé in flight. A commercial aircraft door will not open in flight because it is actually bigger than the window frame itself, and the door opens inwards towards the cabin. If you look closely at the top of a jet airliners wings, you'll probably find a row of small metal tabs standing about one inch (2.5čm) tall, especially in front of the ailerons. These are vortex generators, which actually help the air follow the shape of the wing during flight by creating tiny whirlwinds over the wing. Most planes flying internationally have their home country's flag painted on or around their tails. Airline doors and windows are often inset a few millimetres from the fuselage. To open, it must be opened inwards, rotated, and then slipped sideways out of the frame. Generally, the flag is facing the proper way round on the left (port) side of the aircraft, and backward on the starboard side. This is so that they'll expand to be flush with the fuselage during flight. How powerful are jet engines? In May 2000, a chartered jet carrying the New York Knicks basketball team taxied out to close to a line of cars parked on the tarmac. The blast from the taxiing jet flipped head coach Jeff Ban Gundy's car into the air and over three other cars, completely demolishing it. Each engine on a Boeing 747 weighs almost 9.500 pounds (4,300 kg), cost about $8 million USD. and burns about twelve gallons of fuel per minute when cruísing. Altogether the four engines account for about 5 percent of the total weight of a full 747 upon takeoff. Even if you strapped on giant wings, you'could never fly because the human heart can't pump blood quick enough to satisfy the enormous strain of flapping. When flying, a sparrow's heart pumps more than 450 times each minute! One of the strangest forms of lighning is ball lightning, which čan form inside an airplane and appear to be rolling down the aisle while glowing and sparkling. Although it's startling, it has never harmed anyone. The windows in an airport control tower must be tilted out at exactly fifteen degrees from the vertical to minimise reflections from both inside and outside the control tower. Radar can be compared to a flashlight shining in the night sky: when the light hits something, like a bird flying by, it bounces back into your eyes so you can see it Radar uses light waves that the eye can't see; if the radar beam hits an object, it can be picked up by a sensor. Commercial pilots who around 35,000 feet. That fly on international flights sounds pretty far up, but and the flight controllers compare this to the size who the pilots talk to are required to be able to speak English, the size of a typical desktop international Tanguage of flight. When a French airline travel to Germany, all air traffic control communication is handled in English. The larger the airplane, the slower it is flying, the more powerful its The faster an airplane flies through the turbulence, the more stress it can put on the aircraft, so airlines have "rough air" speed rules that instruct the pilots to slow down in turbulent conditions Airplanes often cruise at vortices. If you stngtip below a jumbo jet when it lands, you may even hear a flapping sound and see ribbons of water vapour, both c reated by the wingtip vortex. of the earth itself: If the Earth were shrunk to the globe, the airplane would be cruising at only one - tenth of an inch (2.5 mm) off the surface. Air pressure is serious business. If the cabin depressurizes while you are at cruise altitude and you dont put on an oxygen mask, you could become unconscious within thrity seconds. Even though airliners carry medical kits and can quicky be in radio contact with doctors on the ground, about 100 people die each year while flying, from heart attacks, seizures, or other medical emergencies. The specific rules regarding flight attendents vary among airlines and between countries. The pilots' headsets are always tuned to air traffic control frequencies, but the pilots also communicate with the airlines offices via private radio channels. Before takeoff, the airliners dispatcher, confirms the number of passengers onboard, the amount of fuel loaded, the weight of the aircraft, the takeoff speed, whether there are animals onboard or in the cargo hold, and the airports general security status. The captain and the first officer always eat different meals during a flight, just in case one of them gets sick. On US based airlines there must be at least one flight attendant for every fifty seats of the aircraft. In such a emergency, pilots will immediately descend to a self altitude; if they didn't, anyone not wearing a mask could die within minutes. s facts-of-aviation/ gotronic SOURCE: 0.
