I don't buy the explanation of power saving in case full thrust is needed as nowaday lights don't need a lot of energy and the crew says we can use the smaller reading lamp to continue reading. Airlines require pilots to dim or turn off the lights during takeoff and landing for the same reasons that the shades need to be open. It's for your own safety. Answer (1 of 49): Most aircraft windows don't open but If you are referring to why they open the window blinds/shades when landing then that has to do with safety. — Billiam Conner, Kentucky A: It would be very unusual for an airplane to sit on a . These include the engines, flaps, landing gear, and aerodynamic noise. Before landing and taking off, I notice the lights inside commercial aircraft are greatly reduced. . if the engine is still turning (windmilling) the suck/squeeze/bang/blow cycle occurs. Even if the mags=off. The opening of engines during landing is technically known as a thrust reversal mechanism, and diverts the airflow in the opposite direction. This helps to slow it down by acting against the aircraft's forward travel. The plane found its way to an airport in Buffalo where ambulances and fire engines waited on the runway. To explain the process on a basic level, air is 'sucked' into the engines, but then instead of moving to the rear, it is ejected through new openings in the aircraft's side that . This is completely necessary, as the engines need to propel a lumbering aircraft that may weigh over a million pounds to speeds of approximately 170 Miles/hour (274 Km/hour . The majority of airline evacuations happen as a result of events during takeoff and landing. To explain the process on a basic level, air is 'sucked' into the engines, but then instead of moving to the rear, it is ejected through new openings in the aircraft's side that . Dimming or turning off the lights also aids the pilots. This helps reduce the speed of the airplane, and allows for landings on shorter runways. The only people who can see the engines and what happens in the surroundings, are their passengers. Jet engines split open in order to slow down the speed of airplanes when landing. The engines create strong accelerations, similar to pushing the pedal to the floor in an automobile. Mags are timed to the cylinder suck/squeeze/bang/blow cycle. Dimming or turning off the lights also aids the pilots. Even if both engines go out, the plane won't just fall out of the sky. — Billiam Conner, Kentucky A: It would be very unusual for an airplane to sit on a . It becomes a .

Dec. 25—LYME — A plane was forced to make an emergency landing after a mechanical issue on Friday, which was witnessed by a woman who saw the pilot signaling from the aircraft. Why airplane takeoffs and landings are so dangerous. This helps to slow it down by acting against the aircraft's forward travel. . If anything happens during take-off and landing - the most risky stages of every flight - then your eyes will already be used to the dark or the light outside, and you'll be able to . Why would they do this, and how do they keep the aircraft from moving when the engines are going full-blast? In the 1920s, aircraft designers already recognized the need to reduce the drag on an airplane in order to improve its speed, fuel efficiency, and maneuverability. The major reason why most planes have retractable landing gear is in order to reduce the amount of drag acting on the aircraft during flight. In an emergency, brakes alone can stop a commercial jet, but the heat produced may be enough to melt the plane's tires, he says. Larger turboprop aircraft have propellers that can be adjusted to produce rearward thrust after touchdown, rapidly slowing the aircraft. The reason why they want all shades up is because, airlines rely on passenger's vision of the whole outer aircraft. The myriad reasons why plane window blinds must be open during takeoff and landing all contribute to helping in the event of sudden and unexpected emergencies. Combine the two and one concludes that it is a good idea to open the windows during takeoff and landing. Airlines require pilots to dim or turn off the lights during takeoff and landing for the same reasons that the shades need to be open. But "reduce" is a vague term.
