how do planes fly carrying all that weight in different weather condtions?

Answer 1

Because they have perfect shape to fly through the air and the high speed jet engines keeps it moving.

Answer 2

An earlier responder suggested referring to a certain NASA web site. However, the explanation given there is wrong! The NASA site explanation is in terms of the Bernoulli effect, in which an increased stream velocity results in a lower side pressure. The effect is real, but if that were what made airplanes fly:
- Helicopters could not fly: they have (for technical reasons) symmetrical airfoils on which the path length of the top and bottom airfoil surfaces is the same.
- The Wright Flyer could not fly; it has a single-surface wing, so the path length top and bottom is the same.
- Airplanes could not fly upside down. (Which, of course, they can do quite nicely.)
So, how does it actually work? The airfoil impinges on the air stream at an angle, called the angle of attack. The air below the airfoil is compressed by this, and the air above is rarefied because the leading edge of the wing catches some air that would otherwise flow across the top of the wing and forces it down instead. The downward motion thus imparted to the air results in an upward force on the wing (momentum is conserved). If you are imparting momentum to an airstream, you can push a lot on a little bit of air, or a little bit on a lot of air; the former condition applies when the airplane is moving slowly and the latter when it is moving fast.
Because the force vector resulting on the wing has a horizontal component as well as the vertical lift component, there is drag (in this case, what is called induced drag). The purpose of the engine(s) is to supply a forward force to overcome this drag in combination with the drag (parasitic drag) which arises because the airplane has to push its body through the air as well as the wings.
It should be obvious from all of this that the weather has nothing to do with it. Modern aircraft carry instruments which give the plane's position and orientation even if you can't see out the windows.

Answer 3

First let me say that most aircraft avoid serious weather just like you would avoid trees and buses while walking thru the park. An airplane encountering serious weather could be damaged and crash. As for flying thru a little rain, the jet engines must be able to withstand injesting a huge amount of water (and even some ice and the ocassional smaller bird) without failure before the FAA will certify it to go on an airplane. The airframe itself is tremendously strong for its weight, and yet is flexible enough to take a lot of bumps without damage.

I think it's really funny that one respondant says NASA's information is wrong.

Helicoptor rotor blades are actual airfoils, shaped like wings, NOT symetrical on both sides. I have no idea what "technical reasons" this person is talking about, but all the helicoptors I have worked on in the past 20 years have flown with airfoil shaped rotor blades.

The Wright Flyer's wings are also airfoils, the leading edge parially blocks flow along the under-wing (much like the cab of a pickup truck blocks air from the truck bed) so that it acts like a modern wing but works much less efficiently.

Angle of attack effects the efficiency of an airfoil, it is NOT the method by which airplanes fly. In fact, when the angle of attach reaches a certain point the airflow over the top of the wing is esentially cut off and the wing loses lift (stalls). This method of moving air is what your household fan or a ship's propeller does (even aircraft propellers are airfoils for increased efficiency), using its angle to push the air by brute force. This doesn't produce lift, on the contrary it really only produces drag, and is a very inefficient way to try and get a plane in the air. It would take far more engine power than current aircraft use. If this were the way airplanes really flew, then DaVinci's helicoptor would have flown centuries ago.

I think the only rarified air around here is that breathed by that respondant.

Answer 4

THe shape of the wings makes the pressure on the bottom surface of the wing higher than the pressure at the upper surface of the wing.so the net pressure working on the wings is upward pressure which provides lift to the aeroplane.
if you hold out a piece of paper infront of you and blow air from your mouth above the piece of paper, you would see the piece of paper is trying to lift up rather than going down! Paradox but fact.
motion of the aircraft and shape of the wings make this pressure differential possible and the plane flies.

Answer 5

Aircraft have a design specification.
The manufacturers will have tested it in wind tunnels & using prototypes etc. During this period, calculations will be made for maximum altitude, speed, endurance, where ice forms, maximum crosswind speeds, the list just goes on & on. From these calculations, the operating limitations are set for the aircraft, which determines when the aircraft can fly & when it can not.

Answer 6

convinced, oftentimes planes fly at round forty,000 ft or so, and fly above climate, each and every now and then they r alloted a decrease altitude in the flight plan, because of alternative site visitors at intense altitudes, each and every now and then by using technical mess united stateslike pressurization or airconditioning issues, structure failure or cracks, they fly at a decrease altitude, say 25,000 ft or maybe decrease. those r uncommon occurences. yet when there's a intense strom on a similar situations, such issues alway coincide, it leads to a catastrophic twist of destiny because the Air France flight 447. the instantaneous the black packing boxes r got here across, shall we get a clearer and extra constructive photo of the themes confronted by Air France Flight 447.

Answer 7

to give you some idea how a plane takes off. when driving
your car open window stick arm out ,and you will find that due to momentum your arm will rise up this gives you the basics of flight

Answer 8

the engines and wings of the aircraft produce massive amount of life and speed

Answer 9

Simple: 1/2 RhoV2S that about sums it up :-)
