Why do the airplanes fly at higher altitude during the long flights
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..
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.
Are planes checked before every flight
All good pilots use pre-flight checklists before every flight. A pre-flight checklist is a comprehensive list of actions that should be completed by the pilot on every flight, prior to takeoff.
Do planes fly over Everest
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. 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.” … The Himalayan region has almost no flat surfaces.
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.
Can you hear a plane at 30 000 feet
While immovable, they could detect aircraft as far as 15 miles away—a significant early warning in those days. Really, though, you don’t even need specialized equipment; there are plenty of times, on a quiet day, where I’ve heard commercial airliners far overhead, at 30–40,000 feet, using just my ears.
Why do commercial airplanes 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 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.
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.
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.
Why do planes fly at 36000
Since 36,000 feet is a further 7000 feet higher than the peak of Mount Everest, the air up there is pretty thin. That allows the aircraft to travel faster while using less fuel. Flying at this height also lessens the chance of a plane coming into contact with something else.
Do pilots sleep while flying
Do pilots sleep in flight? The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.
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 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. 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.
