Quick Answer: What happens if a commercial plane flies too high?

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.”

What is the maximum height a commercial plane can fly?

Limits set for commercial aircraft

Although, of course, air traffic control in each airspace has ultimate authority over an aircraft’s precise altitude. Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a ‘service ceiling.

Why do commercial airplanes 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.

Can commercial planes fly at 50000 feet?

Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. … The retired supersonic airliner’s turbojet engines were more efficient at a faster speed.

Why do commercial airliners fly at 35000 feet?

The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.

Why planes do not fly over Tibet?

According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

Why do pilots prefer to fly at 36000 feet?

The biggest reason for this altitude lies with 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.
