Can planes fly at 50000 feet?
Answer: Every airplane has a certified maximum altitude.
A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence..
What is the highest feet a plane can fly?
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.
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 eject toilet waste?
In a plane toilet, strong suction and teflon-like walls pull excreta away using a small quantity of water. As you press the flush button, the vacuum at the bottom of the bowl sucks the waste into a holding tank. The waste is sucked into a tanker at the airport and then dumped.
Do pilots get scared of turbulence?
Turbulence isn’t dangerous Pilots find it perplexing that so many people are afraid of turbulence. It’s all but impossible for turbulence to cause a crash. We avoid turbulence not because we’re afraid the wing is going to fall off but because it’s annoying.
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.”
Can a human survive at 35000 feet?
1 Answer. Long term, no, it is not. Any exposure to pressure altitudes over 26,000 ft will eventually cause death from hypoxia, even with acclimation to the higher altitudes. There is a period referred to as Time Of Useful Consciousness (ToC) associated with hypoxia.
How cold is it at 50000 feet?
U.S. Standard Atmosphere Air Properties – Imperial (BG) UnitsGeo-potential Altitude above Sea Level – h – (ft)Temperature – t – (oF)Absolute Pressure – p – (lb/in2)40000-69.702.73045000-69.702.14950000-69.701.69260000-69.701.04916 more rows
Can planes still take off in snow?
To look at this another way, rain and snow are largely safe to fly in, and by extension to take off and land in. No inclement weather of any sort should disrupt your flying at all unless it is very severe, and there’s almost no chance weather will bring down the aircraft you’re on.
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.
Why do planes not freeze in the air?
However, when an airplane comes in contact with it, the airplane acts as the freezing nuclei, freezing the droplets immediately. At an altitude of 35,000 feet, however, the clouds are made of ice crystals so no supercooled droplets exist thus, airplanes do not face icing issues.
What happens if an aircraft 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.” …
Why do planes do not fly over the Pacific?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.
How many degrees do you lose per 1000 feet?
If there’s no snow/rain falling from the sky, then the temperature decreases by about 5.4°F for every 1,000 feet up you go in elevation & decrease the same for every 1,000 feet you go down.
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 lightning strikes a plane?
For safety reasons, planes hit by lightning mid-flight undergo inspection after landing but in most cases, the aircraft is either unharmed or sustains only minor damage. … Lightning typically strikes a relatively sharp edge of a plane, like a wingtip or nose, and the current exits via the tail, according to Hansman.
How cold is it at 37000 feet?
The Troposphere is closest to the surface of the earth, and as you climb into it, on average, the temperature decreases by roughly 3.6°F for every 1,000 feet. This means that at cruising altitude of 37,000 feet, the outside air temperature could be minus 76°F.
Can a human survive at 37000 feet?
At altitudes above 65,000 ft atmospheric pressure approaches that of space, i.e., a vacuum (NASA). Between 62,000 and 63,500 ft (18.9 – 19.4 km), blood at body temperature (37oC) begins to boil. This is the point beyond which humans absolutely cannot survive in an unpressurized environment.
Why do planes fly at 40000 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. Spending less on fuel is also great for airlines, for obvious reasons.
Why do pilots salute before takeoff?
All pilots salute to signify they are ready for takeoff. They aren’t even supposed to put their arms above the canopy rail to avoid accidental shots. There are hold bars on the throttles of some planes to avoid a situation where the throttles go to idle during the shot.
At what altitude can a human 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.
