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.
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 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 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.” …
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.
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 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.
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.
Can a plane accidentally fly into space?
It is not possible to fly a plane in space. … Instead, space travel relies on rockets. A rocket carries its own air or oxygen supply so can operate outside the earth’s atmosphere. Of course, it is possible to use rockets to put a plane into space then use the wings to safely land after re-entering the atmosphere.
Why do jets 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 do 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.
How many years can an airplane fly?
The average airplane can fly for around 25 years; some can fly for 30 years but never more than that.
What would happen if a plane window broke?
If by a very slim chance, the plane’s window had cracked mid-air, things would have gone south very quickly for passengers. As The Independent explained, above 10,000 feet the plane would depressurize and there would be an immediate drop in oxygen for passengers.
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.
What happens if an airplane gets struck by lightning?
Although passengers and crew may see a flash and hear a loud noise if lightning strikes their plane, nothing serious should happen because of the careful lightning protection engineered into the aircraft and its sensitive components. Initially, the lightning will attach to an extremity such as the nose or wing tip.
