Frequent question: Why do commercial planes fly so high?

The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.

Why do commercial airliners fly at 35000 feet?

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.

What happens if a plane flies too high?

When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …

How high can a commercial plane fly?

FAQ » General FAQs » How high do commercial planes fly? The approved maximum altitude for most commercial aircraft is 42,000 feet.

Why do planes fly at 40000 feet?

1. Many flights are not as full as they were, so they are lighter and can fly at higher altitudes, which are more fuel-efficient. … Many business jets can fly higher, routinely cruising in the high 40,000s. The maximum altitude for many business jets is 51,000 feet.

Can a plane fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

Do planes eject toilet waste?

Blue ice, in the context of aviation, is frozen sewage material that has leaked mid-flight from commercial aircraft lavatory waste systems. … Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a plane’s septic tank.

Can a plane accidentally fly into space?

There’s simply no air to travel over and under an airplane’s wings in space, which is a main reason airplanes can’t fly in space. Another reason airplanes can’t fly in space is because they require air to generate combustion. … Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.

Why do planes not get struck by lightning?

Path of least resistance. Aluminum leads current. Lightning will usually hit a protruding part of the plane, such as the nose or the tip of the wing. The aircraft then flies through the lightning flash, which travels along the body, having chosen the path of least resistance.

What is the highest height 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.

Why do planes do not fly over the Pacific?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

Do planes fly above rain?

Rain doesn’t usually affect a flight much. Combining with hefty winds causes extra challenges to flight planning. … Heavy rain could affect visibility, but planes generally fly on instruments anyway, so this will not be an issue in itself.

Why do planes fly faster at higher altitudes?

The higher the better

One of the central reasons behind aircraft altitude is that, as the air gets thinner with every foot climbed, planes can travel more easily and therefore move faster and burn less fuel, saving money.

Why don t commercial jets fly higher?

Carriers avoid a massive amount of turbulence that would occur at lower levels. Along with this, most thunderstorms, severe weather incidents and birds can be avoided while above 35,000 feet. Also, the air is thin enough to reduce the aircraft’s drag, increasing its fuel efficiency.

Can planes land on autopilot?

Yes a plane can land by itself using a system that is often referred to as “autoland”. The pilots can program the auto-pilot to carry out the landing automatically whilst the pilots monitor the aircraft. … Automatic landings probably account for less then 1% of all landings on commercial flights.

A: The standard for vertical separation is now 1,000 feet. You were right about it being 2,000 feet until January 20, 2005, when the U.S. implemented Reduced Vertical Separation Minima (RVSM).
