What's the slowest a plane can fly and stay in the air?

What's the slowest a plane can fly and stay in the air? Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

Why is 747 retired?

Most airlines had retired their 747 fleets in favor of a new generation of long-haul aircraft, which carry fewer people than the 450-passenger giant, and, with just two engines versus the 747's four, burn less fuel.

Do planes have breaks in the air?

Virtually all jet-powered aircraft have an air brake or, in the case of most airliners, lift spoilers that also act as air brakes.

What mph do planes not fly?

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing.

Why do all Boeing planes end in 7?

The 700 series aircraft end with a seven for marketing purposes and to create symmetry in the designations, making it easier to remember iconic aircraft like the Boeing 747.

Do planes ever pass each other?

Flying in the crowded skies over Europe or North America, it is quite common to see other aircraft whizzing past, either above or below.

Can planes take off in thunderstorms?

Can a plane take off in a thunderstorm? Technically, it is possible, but pilots and air traffic experts prefer to keep planes on the ground when a storm is present and wait for it to calm down before setting off.

What is the highest altitude a 747 can fly?

Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).

What seats on a plane are the safest?

The middle seats are safer than the window or aisle seats, as you might expect, because of the buffer provided by having people on either side, professor Drury said to the Conversation. He noted that sitting next to an exit row can ensure a quick exit if there is an emergency, except in case if there is a fire.

Can a plane fly 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.

How fast must a plane fly to stay in the air?

In general, we can say that the estimate of a commercial aircraft is that it stays in the air flying above 200 km/h – or approximately 108 kn (knots, unit of measurement commonly used in aviation).

How far can a 747 fly without engines?

For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft).

What does 747 stand for?

What does 747 mean? The most well known aircraft in the 7×7 series is the Boeing 747, which also goes by the nickname “jumbo jet.” The 747 made aviation history. It was designed in the 1960s as a response to an increase in air traffic. It was the largest civilian airplane in the world.

Why do planes slow down mid flight?

All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.

What keeps planes in the air?

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

What happens if a plane lands too fast?

Transferring too much weight onto the nosewheel causes a situation called wheelbarrowing, which can lead to a loss of directional control, prop strike, or nose gear collapse. On top of those problems, with little to no weight on your main landing gear, you have little braking action.

Why do planes take off so steeply?

The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.

Can planes take off in heavy rain?

While rain has a very slim chance of canceling a flight, there can be a minor chance that rain will delay it. Rain is just water, no matter the pressure. Modern aircraft can generate lift regardless of the heaviness of the rain. Planes can and will take off and land in the rain.

Why do planes speed up before landing?

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.
