Can planes take off from a treadmill conveyor belt?

Can planes take off from a treadmill conveyor belt?

There’s no way that plane could take off. The conveyor belt keeps pace with the speed of the plane, which means the plane remains stationary from the POV of an observer on the ground, and therefore cannot lift off. Then I read Cecil’s answer again this evening and I’ve changed my mind; I’m fairly certain he’s right.

At what speed does an airplane lift off?

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

Can a plane take off overweight?

Your weight will directly affect whether or not you will have enough runway in some cases. So, you might find that taking off at gross weight in your aircraft won’t give you enough of a safety margin, but taking off at half tanks will. In this case, topping the tanks off at your destination may not be advisable.

Can a jet take off without flaps?

A: No airliners take off with full flaps. High-altitude airports and higher temperatures cause airplanes to use reduced flap settings to ensure adequate climb performance. This requires accelerating to a higher speed before lifting the nose for flight (rotation).

Can a 747 take off on a conveyor belt?

Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction. Can the plane take off? The practical answer is “yes”.

What speed does 747 take off at?

The 747 goes from its approximate takeoff speed of 200 mph (89.4 meters per second) to 0 mph in 27 seconds.

Why do planes slow down 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.

Why do planes stop before taking off?

Most planes use a long runway before takeoff to gain enough speed for the plane to lift up into the air. Most airplanes can take off only if they are moving fast enough. The force of lift needs to be stronger than the force of weight.

Can a 400 lb person fly?

FAT ISSUES IN THE AIR

There is no legal weight limit for passengers on U.S. commercial flights but some airlines such as Southwest ask customers who cannot fit into one seat to book two. It says if a passenger cannot lower the armrests on one set they must buy another – whatever they weigh.

Can a size 22 woman fit in an airplane seat?

A size 22 won’t have difficulty fitting in a airline seat, and doing up the seat belt. Don’t worry.

Do pilots land with full flaps?

The general rule is to use full flaps for most landings–but it depends. Using flaps will increase the camber of the wing, improve lift, reduce touchdown speed, give you a better view from the cockpit, and permit more precise management of your touchdown point than not using flaps.

Why are flaps down during takeoff?

Wing flaps are a significant part of the takeoff and landing process. When the airplane is taking off, the flaps help to produce more lift. Conversely, flaps allow for a steep but controllable angle during landing.

Can a plane take off in a thunderstorm?

Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so en route flights always seek to go around them.

Why do pilots say rotate when taking off?

Pilots say rotate because it is a verbal queue that an airplane has reached its predetermined rotation speed (frequently abbreviated to Vr). This is the speed at which control inputs can be applied to lift the nose off the runway and make the airplane fly away.

How do planes stop after landing?

In addition to wing spoilers, airplanes use disc brakes. Airplane disc brakes are similar to the braking system in automobiles. They consist of a pair of calipers that, when engaged, squeeze pads against the rotors of an airplane’s landing gear. Disc brakes are designed to remain static at all times.

What is the scariest part of flying?

Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.

Why do planes turn right after takeoff?

Airplanes may begin turning immediately after takeoff to reduce noise over urban areas, to avoid high terrain and storm cells, at the request of air traffic control, or to turn & get established on course as soon as possible. Most busy airports will have departure routes to help with traffic flow.

Is it better for a plane to crash on land or water?

Its surviving rate is probably greater than on land. Surviving impact perhaps, when landing on water, but if not close to land unlikely to survive for too much longer.

Why do pilots do touch and go?

Touch-and-go landings can perform a crucial safety role when a plane lands with not enough space to come to a complete stop, but has enough space to accelerate and take off again.

Can a 300 pound person fit in an airplane seat?

Will a 300 pound person fit in an airplane seat?

Is there a weight or size limit for airline passengers? Dear Reader, There is no set weight limit for passengers on commercial flights in the U.S., but some airlines, most notably Southwest, require customers who cannot fit in one seat to book a second.

What size needs a seat belt extender?

Check seat belt length before buying a ticket

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.

Why would you do a no flap landing?

A no-flaps landing may be the answer in conditions of strong or gusty winds, when the slightly higher airspeeds you fly improve control responsiveness. And unless your aircraft has manual flaps, a real-world electrical failure could leave you without flaps.

Can a plane land without flaps?

Flare, Touchdown, Rollout
In light airplanes, no-flap landings aren’t exceptionally difficult or dangerous. No-flap landings may require up to 50% more runway distance for stopping. With flaps retracted and power reduced, the airplane will be slightly less stable around the pitch and roll axes.
