Why do planes fly so high?

The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

What happens if a plane flies too high?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

Why does a plane have to fly so high?

The biggest reason for this altitude lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.

What is the highest a plane can fly?

Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a 'service ceiling. ' For example, for the double-decker Airbus A380 'superjumbo' quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet.

Can planes fly at 50000 feet?

The highest certified altitude of an airliner was Concorde's 60,000 feet. Today some of the corporate jets can fly at 51,000 feet. Q: What is the highest cruising altitude allowed? A: Most airliners are limited to 45,000 feet or less.

Why Do Planes Fly So High?

Can planes stop in air?

Airplanes stay in the air because of one simple fact-- there is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way, even if it's in midair 10 kilometers above the Earth's surface.

How cold is it at 40000 feet?

After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.

What do pilots see when flying?

The Horizon

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

Why do planes not fly directly over the Pacific Ocean?

The Pacific Ocean is a massive body of water that will require an extremely large amount of fuel to fly across. Rather than flying directly across the Pacific Ocean, most commercial flights take curved routes because they are actually shorter than shooting straight across a distance.

What happens if plane window breaks?

At cruising altitude, the pressure outside a plane is around two-and-a-half times lower than inside the cabin, so a broken window or a large hole in the fuselage can be catastrophic, causing a blast of air that will suck out seats as well as people.

Do pilots sleep on long flights?

Aviation regulators set the total hours pilots fly and how much sleep they must get between flights. During ultra-long-haul flights, pilots sleep in special cabins, which passengers can't access.

How cold is it at 30000 feet?

A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm). All materials used in airplanes are designed and tested to withstand temperature extremes.

How cold is it at 35000 feet?

At higher altitudes the atmosphere is colder. At 10,600 meters (35,000 feet), (the average cruising altitude of a modern passenger jet) the temperature is about -40°to -51°C (-40°to -60°F).

What is a ghost flight?

A ghost flight is a term used when airlines operate a regularly scheduled route with a plane containing less than 10% of the airline's total capacity. Some say these flights are unnecessarily adding to the environmental crisis, by contributing to carbon emissions without a significant benefit.

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.

What is the longest non stop flight?

The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles.

Can a pilot open his window in flight?

Opening the window

When the aircraft is not pressurized, either on the ground or if depressurized during the flight (intentionally or due to an accident), then pilots can open them. On most modern aircraft, the opening procedure is the same.

How do pilots stay awake?

Managing fatigue is a challenge, particularly when flying overnight (red-eye) flights. Some countries allow pilots to take controlled naps to improve alertness during the landing. So far, the U.S. has not allowed this fatigue mitigation. Pilots keep flight deck lights up, and engage in conversation to help keep alert.

Can planes fly in a blizzard?

While it may seem hazardous on the ground, it is not uncommon for airplanes to fly in snow. This is because planes usually fly above snowfall, which makes it a non-factor for pilots and flight dispatchers. However, this is only true for commercial flights because they fly higher than smaller recreational aircraft.

How cold is deepest space?

Far outside our solar system and out past the distant reaches of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).

At what temperature can planes not land?

Why is it that they can't handle the heat? It turns out that planes can handle cold a whole better than they can deal with heat. As long as the inside of the aircraft is kept warm enough, planes can take off and land in temperatures as low as minus 67 degrees Fahrenheit.

Do planes fly at full speed?

For the typical single-engine plane, you'll be able to fly around 140 mph (122 knots). However, some of the more advance single-engine airplanes, like the Pilatus PC-12 NGX, have a top speed of 334 mph (290 knots).

What speed does a plane take off at?

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).

What is the slowest speed an airplane can fly?

Slowest aircraft

The MacCready Gossamer Condor is a human-powered aircraft capable of flight as slow as 8 miles per hour (13 km/h). Its successor, the MacCready Gossamer Albatross can fly as slow as 9.23 miles per hour (14.85 km/h).
