Almost all medium and large jetliners fit into the same pattern: two engines, straight-tube fuselage, and a conventional tail. Where has all the imagination gone? It’s not that aeronautical engineers have run out of ideas. Instead, the demands for efficiency have driven designs to this narrow range of similarity.
Why are airplanes shaped the way they are?
The shape of an airplane’s wings is what makes it possible for the airplane to fly. … As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up. Using curves to affect air pressure is a trick used on many aircraft.
Do airplanes still have bars?
There’s a handful of aircraft out there that take the flying experience to the next level by offering bar and lounge areas for passengers to relax in. There are six different commercial airlines to date that offer true bar experiences on board: Emirates, Etihad, Korean Air, Qatar, Virgin Atlantic, Virgin Australia.
Why do planes sometimes look like they are not moving?
Clouds move or change shape. Our eye muscles are not good at keeping a steady gaze. As result our own movement adds or subtracts to perceived speed of the plane. A similar problem is statues seemingly moving or nodding at believers.
What causes the airplanes to fly even though they are so heavy?
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.
Why do planes stop in mid air?
No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
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.

Does Qatar A350 have a bar?
There are six rows of seats between doors one and two, so there are a total of 24 seats there. … The cabin on the A350-900 feels incredibly spacious, given that the open area by the second set of doors doesn’t have any bulkheads. Instead the space feels open, and there’s even a small walk-up bar of sorts right there.
Why do planes turn after takeoff?
Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting. The sensation of “dropping” comes from the retraction of the flaps and slats. The rate of climb is reduced, causing it to feel like a descent.
Can planes suspended in the air?
An airplane cannot stand still in the air as it requires air flow over the wings to create lift. An airplane can be stationary over the ground if the air is moving over the ground quickly enough. … In this video the airplane appears to be flying must slower than it actually is due to the angles viewed and other factors.
Can an airplane stay in the air without moving?
To stay in the air and sustain its flight, an aircraft needs to be moving forward. … If the plane stopped flying forward, it could not produce lift, an thus could not stay up, unlike the helicopter which uses a propeller to stay airborn.
How long can a plane stay in the air?
Planes can now fly for 21 hours non-stop.
How can a plane fly upside down?
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. The angle of attack is the angle between the axis of the wing and the direction of incoming air. Public Domain Image, source: Christopher S.
