What are the four forces of flight?
*weight
*lift
*thrust
*drag
what is weight?
weight is the force that pulls the airplane towards the ground.
what is lift?
List ifs the force that enables an aircraft to take off and fly.
what is thrust
thrust is the force that moves the plane foward.
what is drag
drag is the force that slows the airplane down
what does gravity do to the plane so that is weighs so much
the gravity pulls the airplane toward the ground
how much does a sport plane and a jumbo jet weigh
Sport plane:2,000lbs
Jumbo jet: 800,000lbs
how many passengers can a small, single engine sport plane and a jumbo jet carry?
Sport plane:4 ppl
Jumbo jet: 360ppl
what is lift?
lift is the force that enables an airplane to rise off the ground and fly
what part allows the plane to arry its own weight through the air
the wings allow the plane to carry its own weigh through the air
if a jumbo jet weighs 800,000lbs, how many lbs of lift are needed to make the plan take off?
the lift would have to be more than 80,000lbs to make a jumbo jet pull off
what is cruising altitude?
cruising altitude is the height an airplane reaches when it flies straight ahead w/out going up//down
what must be equal in order for a plane to fly straight and level?
for the plane to fly straight and leve the life must be equal to the weight.
in order for a pilot to land what force must be less than the weight of the plane?
for the plane to land the lift must be less than the weight
what is it about the wings that helps the plane lift?
the shape b/c the different shape creates different lift.
what do you call the curved part at the front of a wing
the front part of a curved part @ frong of wing is called leading edge
What do you call the pointed end of the ing?
the pointed end of the wing is called trailing edge
what is another word for wingg shape?
wing shape is also known as the airfoil
what is a flat bottom airfoil?
a flat bottom airfoil has its name b/c of its flat bottom
What did bernouli discover many years ago?
he discovered that when a fluid moves from a large area into a smaller are the speed of the fluid increases.
w/ higher speed pressure....
W/ higher speed, then pressure gets lower
w/ lower speed the pressure...
w/ lower speed then pressure gets higher
w/ a flat bottom airfoil which side of the wing is flat and which side of the wing is curved
in a flat hottomed airfoil the wing is curved at the front, and the bottom part is flat
when a wing moves throught the air what does it do to the air?
once the wing goes through the air it is slicing it into halfs
when the wing moves through the air where must the air move above the wing?
the air below the wing should slide straight below the wing.
once the air moves abobe and below the wing thea aire comes together again. where does air come together again
the air comes together at the trailing edge
the air has a greater distance to travel above the wing. why is this?
the greater distact is above the wing b/c it's curved
where does the air travel faster above the wing//below?
the air travels faster above the wing.
describe what happens to pressure when air moves rapidly on one side of the wing and slowly on the other side?
when this happens a difference in the pressure is happening
remembering bernouli's equation what happens to pressure when air speed increases?
when the air speed increases the pressure gets lower
since the air speed above the wing is faste than the air speed under the wing what happens to the pressure above the wing
when this happens the pressur reduces
since the air speed under the wing is slower than the air speed above the wing, what happens to the pressure under the wing?
when this happens the pressure under the wing becomes greater and pushes the wing forward
what is produced when there is a difference in pressure under the wing?
when there's a difference in pressure above the wing [[vs]] under the wing it produces lift
\/+/\=/\.. what does this equation mean?
this figure explains that low pressure = high pressure= lift...
low pressure above wing and high pressure below wing=lift
each plane has to travel as a determined speed in order for the ing to produce enough lifet to fly. what is theis speed called?
the speed that the plane has to travel at is called miimum
what is the minimum flying speed for a jumbo jet
the minimum flying speed for a jumbo jet is 160mph
what is the minimum flying speed for a spor plane?
the minimum flying speed for a sport plane is 60moh
why do you think a jumbo jet needs a lnger runway than a sport plane?
i think a jumbo j et needs a longer runway b/c it flies higher up into the air
since the air speed above the wing is faste than the air speed under the wing what happens to the pressure above the wing
when this happens the pressur reduces
since the air speed under the wing is slower than the air speed above the wing, what happens to the pressure under the wing?
when this happens the pressure under the wing becomes greater and pushes the wing forward
what is produced when there is a difference in pressure under the wing?
when there's a difference in pressure above the wing [[vs]] under the wing it produces lift
\/+/\=/\.. what does this equation mean?
this figure explains that low pressure = high pressure= lift...
low pressure above wing and high pressure below wing=lift
each plane has to travel as a determined speed in order for the ing to produce enough lifet to fly. what is theis speed called?

the minimum flying speed for a jumbo jet is 160mph
what is the minimum flying speed for a spor plane?
the minimum flying speed for a sport plane is 60moh
why do you think a jumbo jet needs a lnger runway than a sport plane?
i think a jumbo j et needs a longer runway b/c it flies higher up into the air
