An aircraft in straight and level, constant velocity flight is acted upon by four forces: lift, weight, thrust, and drag. The opposing forces balance each other; in the vertical direction, lift opposes weight, in the horizontal direction, thrust opposes drag.
In aviation, a flight level ( FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA surface pressure of 1013 hPa or (29.92 inHg ).
An airplane in flight is always in the middle of a tug-of-war with the four forces. For an airplane to takeoff, thrust must be greater than drag and lift must be greater than weight. To maintain level flight, lift must equal weight and thrust must equal drag.
10 mar 2024 · Flight Levels (FL): Here’s the definition of a Flight Level by the ICAO (International Civil Aviation Organization): “A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals.”
11 gru 2021 · A jet engine is a machine that converts energy-rich, liquid fuel into a powerful pushing force called thrust. The thrust from one or more engines pushes a plane forward, forcing air past its scientifically shaped wings to create an upward force called lift that powers it into the sky.
31 maj 2022 · The four forces making up the principle of flight are lift, weight, drag, and thrust. The forces all interact together to determine an airplane’s trajectory. Lift and weight are opposing forces, as are thrust and drag. All are equally important, and they must be balanced to maintain level flight.
21 lip 2022 · In flight, the airplane rotates about the center of gravity. Flying encompasses two major problems; overcoming the weight of an object by some opposing force, and controlling the object in flight. Both of these problems are related to the object’s weight and the location of the center of gravity.
