by running and jumping off the ground, also by flapping their wings -Although SOME birds (like the Albatross) have a hard time flapping, THEY HAVE TO WAIT for a strong breeze. Airplanes' wings are thicker at the front of the wing than at the back of the wing. This is in imitation of birds' wings.

What shapes were most common and why on early kites?
Triangle is still the most common. The shape cuts into the wind with little to no resistance and then spans out to create lift. This also gives the kite direction. Airplanes have the same general shape.
How much weight can a mini excavator lift?
An average 3 ton mini excavator will lift approx 1400kg, almost half the weight of the machine as a general rule of thumb
How is lift created?
Generally, lift is created when the pressure below an object is greater than the pressure above it. For example: an airplane wing is curved on top to allow for air to seamlessly pass over, creating low pressure on the upper surface and the wing is obstructed on the bottom, creating higher pressure to lift the wing. As for a helicopter, the air is pushed down by the propeller, causing high pressure below the rotation plane, causing lift.
What is the name of a simple seat hanging on a cable?
A chair lift
What are the 4 forces on an aircraft?
The 4 main forces of flight are: drag, thrust, lift and weight
How do birds and bats create effective wings?
Birds have streamlined wings that create lift and reduce drag, allowing them to efficiently glide and soar through the air. Bats have flexible wings with multiple joints that can change shape and surface area, providing maneuverability and agility in flight. Both adaptations help birds and bats generate lift and thrust to fly effectively.
Which parts of the plane create lift?
The wings and horizontal tail surfaces create lift.
What do you need to create lift?
God
Can parrots fly upside down?
All birds fly only right-side-up. In order to create lift, they must flap their wings down, and they are specially shaped for this.
What is the difference between a helicopter creating lift and anairplane creating lift?
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
What makes airplane fly?
Lift! The wings on a plane create an upward lift.
What does the difference in air presssure above and below a birds wing cause?
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
What bird can lift the highest weight?
Birds do not lift weights.
Do birds fly because of a magnetic field?
No, birds do not fly because of a magnetic field. Birds fly by using their wings to generate lift and thrust. They navigate using a variety of cues, including landmarks, the position of the sun and stars, and Earth's magnetic field.
Are birds wings flat for increasing lift?
If they were flat they would generate no lift and birds could not fly. Aeroplane wings are very similar in shape to bird wings - they are nearly flat underneath and convex on top.
Will a lorry with birds on it weigh the same if all the birds lift up in the air?
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
Which feather is important for flight?
The large one on a birds wings; they produce lift.
