Why do commercial airliners 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..
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 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.
Why is it forbidden to fly over the Taj Mahal?
The Taj Mahal Although there’s no official no-fly zone over the ivory mausoleum, there is a mile-and-a-half radius above the historic site which security agencies consider to be a no-go when it comes to flying. This is because of security reasons – as well as risks to the building’s white marble from plane pollution.
How do female fighter pilots pee?
The female version has a pad-like receptacle that fits under the flight suit. Both versions then feed urine to a disposal bag strapped to the leg.
Do pilots sleep while flying?
The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice.
Do pilots get scared of turbulence?
Pilots are trained in coping with turbulence and will attempt to make the flight as smooth as possible. Weather is typically a common cause of turbulence and pilots will typically fly a route that goes around any storm.
Is gas mileage better at higher altitude?
Fuel economy improves at higher altitude in all engines because the pumping work is reduced. As you go up, a lower manifold vacuum is required to move the car. The lower vacuum means lower pumping work and the result is better fuel economy. This also explains the reduced power.
Can a plane fly with one wing?
No, an airplane cannot fly with only one wing. In order for a plane to stay stable in air, it has to maintain balance. With only one wing, the weight is shifted to one side of the plane.
How do pilots pee?
Peeing into a tube doesn’t work for everyone for some obvious physical reasons, so today’s fighter pilots urinate into “piddle packs,” plastic packs that convert urine into a gel for disposal, but the method involves partially undressing while sitting strapped in a tiny cockpit and flying a multimillion-dollar jet.
Does altitude affect flight time?
Planes can fly much higher than this altitude, but that can present safety issues. Flying higher means it would take a longer time to return to a safe altitude in case of an emergency, like rapid decompression, Beckman says.
Why is it more efficient to fly at high altitude?
They work better at high altitude firstly because the air is cooler. Cool air expands more when heated than warm air. … Low density causes low drag and therefore the aircraft flies much faster at high altitude than on low altitude when it is given the same thrust.
Does altitude affect engine performance?
Reduced oxygen in high altitudes can lead to inefficient, sluggish engine performance because there is less air to feed the internal combustion engine. Generally speaking, an engine loses three percent of its rated power for every 1,000 feet of altitude gained.
Are turbos better at high altitude?
The high-altitude performance of a turbocharged engine is significantly better. Because of the lower air pressure at high altitudes, the power loss of a naturally aspirated engine is considerable. … The turbocharger itself acts as an additional silencer.
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.” …
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 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.
How much HP do you lose at high altitude?
As a general rule, a naturally aspirated combustion engine will lose 3% of its power for every 1,000 ft of elevation gain. If you have 100 horsepower at sea level by the time you get to 5,000 feet of elevation your engine is making 85 horsepower. At 10,000 feet of elevation your engine will make 70 horsepower.
Why can’t planes fly over Messi’s house?
– The airspace is restricted because the sheer volume of aircraft would interfere with the natural wildlife in the area. – “No-Fly Zones” help preserve environmentally protected areas.
Has anyone survived a plane crash?
He was the sole survivor of Vietnam Airlines Flight 815, which had 65 deaths in total. The oldest sole survivor is Alexander Sizov, who was 52 years old when the Lokomotiv Yaroslavl plane crash occurred on 7 September 2011, with 44 fatalities. Another sole survivor is a former Serbian flight attendant, Vesna Vulović.
Do pilots have a toilet in the cockpit?
Answer: There are very strict protocols for a pilot to use the lavatory during flight. This ensures that security considerations are mitigated while meeting the physiological needs of the pilots. Yes, pilots can leave the flight deck to use the lavatory.
