Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.
What is 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.
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.
What is the highest altitude you can fly without oxygen?
When the altitude of an airplane is less than 12,500 feet, there is no supplemental oxygen required for anyone in a private plane. From 12,500 feet to 14,000 feet, supplemental oxygen must be used by the required flight crew for any portion of the flight that is more than 30 minutes.
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.” …
Do planes fly over Mt 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.”
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.
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.
Is there turbulence at 50000 feet?
A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.
At what height can you not breathe?
An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us. By comparison, the summit of Mount Everest (the Earth’s highest mountain) lies at 29,141 feet.
At what altitude does it get hard to breathe?
It refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life for an extended time span. This point is generally tagged as 8,000 m (26,000 ft, less than 356 millibars of atmospheric pressure).
Do you need oxygen at 10000 feet?
For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.
Can a plane accidentally fly into space?
As explained by NASA, airplanes are able to fly because of lift. … A main reason airplanes can’t fly in space is because there is no air. According to NASA, large commercial airplanes typically can’t fly higher than 7.5 miles. At this altitude, the air isn’t dense enough to support a large airplane.
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.
