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.
What is the maximum height a 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?
Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. … However, many light aircraft have to cruise below 10,000 feet because they don’t have the luxury of pressurized cabins like jetliners.
What does FL180 mean?
FL180 and FL300 stand for Flight Level 180 and Fight Level 300. Flight levels are spaced 100ft apart on an altimeter that is set to the standard sea level pressure (QNE) of 1013.25 hectopascals or 29.92 inches of Mercury.
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 cold is it at 35000 feet?
How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.
What happens if a plane fly 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.” …
Can you breathe at 35000 feet?
Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.
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.
How high can a 747 fly?
The Boeing 747–8 has a ceiling slightly over 43,000 feet MSL (above mean sea level). NOTE: The FAA levies strict rules and tests that aircraft manufactures have to abide by and conduct if an airliner is to fly above 40,000 feet.
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 is the lowest flight level?
Aircraft are not normally assigned to fly at the “‘transition level'” as this would provide inadequate separation from traffic flying on QNH at the transition altitude. Instead, the lowest usable “‘flight level'” is the transition level plus 500 ft.
How high do planes fly in KM?
Plane facts and figures
|Aircraft type||Speed in km/u*||Altitude in ft*|
|Boeing 787 Dreamliner||907||40,026|
How high are planes in the sky?
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air.
