What is the maximum height a passenger plane can fly?

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.

Can planes fly at 50000 feet?

It was set in an SR-71 Blackbird in 1976. The speed record is also held by an SR-71, at 2,193 mph. This is not as high or as fast as the airplane can fly, however, it’s absolute speed and altitude limits are classified. Most US military aircraft can exceed 50,000 feet, if they really really try.

Can a plane fly at 60000 feet?

Some aircraft can fly higher

Concorde has been the only significant exception amongst commercial aircraft. It could fly up to 60,000 feet due to the increased lift generated when flying at much higher speeds. At low altitudes, drag would prevent it from reaching its high speeds.

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 highest altitude a 747 can fly?

The 747 max altitude is 45,100 ft. The 757 max altitude is 42,000 ft. The 767 max altitude is 43,100 ft.

Do Planes fly over Mount Everest?

Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … 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.”

How far can a pilot see at 35000 feet?

If you look up into space you are looking through about 62 miles of atmosphere, at 35,000 feet you will be looking through almost 230 miles of atmosphere to see the horizon.

Why do jets fly at 35000 feet?

Due to lower resistance at higher altitudes, commercial aeroplanes can keep moving forward with minimal fuel expenditure. Commercial aeroplanes typically fly between 32,000 feet and 38,000 feet, with the sweet spot being approximately 35,000 feet, which is popularly referred to as cruising altitude.

What’s the highest a plane has ever flown?

On February 17, 1986, The highest altitude obtained by a soaring aircraft was set at 49,009 ft (14,938 m) by Robert Harris using lee waves over California City, United States.

Why do passenger jets 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 a plane accidentally fly into space?

The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion. Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.

Can an airplane stay still in the air?

Can an Airplane stand still in mid-air? Technically, it is possible for an airplane to hover for a few moments, but only in the rarest of circumstances. If weight and lift cancel each other out at the same exact time that thrust and drag cancel each other out, the plane would hover until one of these variables changed.

What happens if a helicopter flies too high?

What Happens If a Helicopter Flies Too High? As the helicopter ascends, the air begins to thin. With thinner air, the main rotor becomes less efficient. The higher the helicopter flies, the slower it ascends due to the reduced power generated by the rotor.

How high can a plane fly without oxygen?

Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.

What is the fastest jet in the world?

The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

Above 28,000 to 30,000 feet with extra oxygen under pressure — normal consciousness and life can be sustained to 50,000 feet. … Yes, but only 21 percent of plain air at sea level atmospheric pressure is helping to push the oxygen into the patient’s lungs (only 21 percent of air is oxygen).
