Airplanes fly
because they are able to generate a force called Lift which normally moves the airplane upward
. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine(s).
How do a plane flies?
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.
What are the 4 things a plane needs to fly?
These same four forces help an airplane fly. The four forces are
lift, thrust, drag, and weight
.
What factors make a plane fly?
The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing. Long flights come when these four forces —
drag, gravity, thrust, and lift
— are balanced.
How do planes fly upside down?
Stunt planes that are meant to fly upside down have symmetrical wings. They don’t rely at all on wing shape for lift. To fly upside down, a stunt plane just
tilts its wings in the right direction
. The way a wing is tilted is the main thing that makes a plane fly, and not the wing’s shape.
How fast do planes fly?
FAQ » Careers, General FAQs » How fast do commercial planes fly? The average cruising airspeed for a commercial passenger aircraft that flies long distances is approximately
880–926 km/h (475–500 kn; 547–575 mph)
.
Can a plane fly with one wing?
Why do all pilots sound the same?
How do planes take off?
A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky.
How do heavy things fly?
When the forces are not balanced, flying objects speed up, slow down or change direction
. This is called acceleration. For example, when the thrust force is bigger than the drag force, an airplane speeds up. When the lift force is bigger than the weight force, the airplane goes up faster.
What does drag do to a plane?
A: Drag is
the force that pushes planes backwards and slows them down as they fly through the air
. Many current innovations in flight are focused on decreasing drag on planes as much as possible. With less drag, planes are able to achieve faster speeds with the same amount of thrust as they had before.
Does a propeller push or pull?
The propeller works by
displacing the air pulling it behind itself
(the action), this movement of air then results in the aircraft being pushed forward from the resulting pressure difference (the opposite reaction). The more air that is pulled behind the propeller the more thrust or forward propulsion is generated.
Can Aeroplane stay in air without moving?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air:
if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too
. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Which fuel is used in aircraft?
Aviation kerosene
, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans.
Which force pulls a plane down?
Gravity
is the force pulling the plane down. When the gravity is stronger than the lift, the plane goes down. Helicopters are really airplanes with moving wings called rotors, which replace the fixed wings and propellers used on an airplane.
Why do planes go faster at cruising speed?
For propeller aircraft, drag is minimised when the lift-to-drag ratio is maximised. However,
the speed for this is typically regarded as too slow
, so propeller aircraft typically cruise at a significantly faster speed. Combustion engines have an optimum efficiency level for fuel consumption and power output.
Is flight based on a true story?
A summary of the true story from the film Flight (2012):
The story is based on the true story of airline pilot William “Whip” Whitaker
, who became a hero after landing a damaged airliner. An investigation into the accident, however, reveals that Whitaker had been drinking and using drugs prior to the flight.
At what angle do planes take off?
Planes slowly angle up during take off at about
2-3 degrees per second
for a Boeing 747. A bit of quick math and using the same Boeing 747 as an example, the average passenger plane has a maximum take off angle of about 10-15 degrees. That’s well within the plane’s tolerances of course.
How much faster is a jet than a plane?
Private jets often fly at the same speed as commercial jets, which on average, fly
547–575 mph
when they reach cruising altitude. Smaller private jets and private aircraft, on the other hand, often have the capability of flying faster than commercial airplanes.
Can you fly a jet?
You can enjoy real Jet Fighter Flights together with an experienced pilot who will control the jet while in the air
. You can fly a jet fighter such as the Supersonic MiG-29 Fulcrum interceptor, the Aero L-39 Albatros or the Hawker Hunter fighter-bomber aircraft.
What is the fastest plane?
Lockheed SR-71 Blackbird
Can plane wings break off?
Can turbulence be severe enough to cause a jet engine to break off a wing? From a practical point,
no, a modern airliner will not lose a wing due to turbulence
. Modern airlines are very tough and designed to withstand extreme turbulence.
How does a plane lift its nose?
Q: How is the nose of an airplane lifted during takeoff? A:
The pilot applies backpressure to the yoke or side stick, causing the elevator in the tail to force the tail down causing the nose to rise
.
Are planes checked after every flight?
The A check is performed approximately every 400-600 flight hours, or every 200–300 flights, depending on aircraft type
. It needs about 50-70 man-hours, and is usually performed in an airport hangar. The A check takes a minimum of 10 man-hours.
What do pilots say before taking off?
There is an announcement like:
“Flight attendants, prepare for take-off please.” “Cabin crew, please take your seats for take-off.”
Within a minute after take-off, an announcement might be made reminding passengers to keep their seat belts fastened.
How can I talk like a pilot?
Why do pilots talk the way they do?
It’s a speech we’re all used to hearing by now and, honestly, if we didn’t, it’d feel a little weird. As we all know, plane passengers come from all walks of life — and
the airlines must do their best to accommodate everyone
. So, pilots are instructed to speak as clearly (and consistently) as possible.
