What is the temp at 30000 feet?
A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm).
All materials used in airplanes are designed and tested to withstand temperature extremes..
Can planes fly at 50000 feet?
Currently, no passenger airplanes are “able” to fly at 50,000 feet or above. Because, at these altitudes, air density is very low, which wouldn’t sustain the heavy weight of the passenger aircrafts. Commercial airplanes have an Absolute Ceiling of 43000 feet.
Why do pilots prefer to fly at 36000 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.
Is there oxygen at 37000 feet?
The Atmosphere This means that at cruising altitude of 37,000 feet, the outside air temperature could be minus 76°F. … It’s for this reason that climbers ascending to the peak of Mount Everest at over 29,000 feet usually require supplementary oxygen.
How cold is the air 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 is the temperature at 40000 feet?
Between 30,000 and 40,000 feet (9,000 and 12,000 m), the cruising altitude of most jet aircraft, air temperature ranges from -40° F to -70° F (-40° C to -57° C).
Can a plane fly at 60000 feet?
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.
At what altitude can a human not breathe?
8,000 mIt 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).
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 happens if a plane flies into space?
If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. 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.
Where does the poop go in a porta potty?
When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant. The portable toilets used on construction sites and at large gatherings such as music festivals are well-known types of chemical toilet.
What is the slowest a plane can fly?
Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.
Can a human survive at 37000 feet?
Above 28,000 to 30,000 feet with extra oxygen under pressure — normal consciousness and life can be sustained to 50,000 feet. Above 50,000 feet with any form of oxygen — sustained human life is not possible without a pressure suit like astronauts wear.
Do planes eject toilet waste?
Some lavatory excrement had leaked out.” Do airplanes ever dump their waste while in flight? Not intentionally. … (The noise may make it seem like the toilet is flushing your waste out into the atmosphere, but it’s not.) Under normal circumstances, the ground crew disposes of the sewage after the plane lands.
Why do planes fly at 38000 feet?
Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. … Another reason why planes don’t fly higher is due to the weight of the aircraft.
Do pilots sleep while flying?
Flight attendants and pilots need their rest as well — but you won’t catch them snoozing in economy class. While flight attendants sleep on bunk beds in tiny crew rest areas, pilots get their own separate sleeping compartments, where they can spend up to half of their time on a long flight.
Why do aircraft 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.
How high can you go before you lose oxygen?
It is the lack of oxygen rather than the reduced air pressure that actually limits the height at which we can 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.
How high can you go without needing oxygen?
26,000 feetWe pass out when the pressure drops below 57 percent of atmospheric pressure — equivalent to that at an altitude of 15,000 feet (4,572 meters). Climbers can push higher because they gradually acclimate their bodies to the drop in oxygen, but no one survives long without an oxygen tank above 26,000 feet (7925 m).
Why do planes 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. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.
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.”
