What are the 4 elements of flight?
It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
Is a 3 hour flight long?
What is considered a short-haul, medium-haul and long-haul flight? A short-haul flight is one of up to 3 hours in duration. Medium-haul flights take 3-6 hours. A long-haul flight runs for 6-12 hours, whilst an ultra-long-haul flight is in the air for over 12 hours.
What makes flight possible?
They float on air much like rafts float on water. … When the air cools, the particles fall back to Earth. Heavier-than-air flight is made possible by a careful balance of four physical forces: lift, drag, weight, and thrust. For flight, an aircraft’s lift must balance its weight, and its thrust must exceed its drag.
What are the 6 fundamentals of flight?
Principles of Flying. (1) Lift, (2) Gravity force or Weight, (3) Thrust, and (4) Drag. Lift and Drag are considered aerodynamics forces because they exist due to the movement of the Airplane through the Air.

Which fuel is used in aircraft?
Jet fuel (Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines (jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene.
What does weight do to a plane?
During a flight the aircraft burns up its fuel, so the weight of the airplane constantly changes. Also, the distribution of the weight and the center of gravity can change, so the pilot must constantly adjust the controls to keep the airplane balanced.

Can a plane fly with one wing?
No, an airplane cannot fly with only one wing. In order for a plane to stay stable in air, it has to maintain balance. With only one wing, the weight is shifted to one side of the plane.
What will cause a plane to speed up?
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
Why can humans not fly?
Humans will never fly by flapping our arms with wings attached, says Mark Drela, Terry J. Kohler Professor of Fluid Dynamics in the Department of Aeronautics and Astronautics. The arms and chest of a human do not have anywhere near enough muscle mass to provide the necessary power.
