Why do planes fly at 40000 feet
Modern airliners are usually built with the ability to function when flying over 40,000 feet.
The service ceiling is the maximum density altitude an airliner can reach according to its design.
However, travelers are more likely find themselves in the air at a cruising altitude of around 35,000 feet..
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 you see Mount Everest from space
Below, is another view of Earth’s highest mountain, taken by Sergey Rryazanskiy (@sergeyISS), who was on ISS Expeditions 37/38 and 52/53. … Oblique view of Mt. Everest, as seen from the International Space Station.
Why do planes cruise around 36000 ft
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.
How cold is the air at 35000 feet
At 35,000 feet the air temperature is about -54C.
What is the highest a plane has ever flown
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
At 35,000 ft The horizon is 221.3 miles, … but it is doubtful that the air will be clear enough that you can actually see that far in the daytime in order to distiguish it. Usually moisture in the air will make haze and will make it impossible to discern, except in very dry cold air, like in the polar regions.
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 fast do planes actually go
Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally going to be different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.
Why do most planes 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.
What happens if a lightning strikes a plane
Aluminum leads current. Lightning will usually hit a protruding part of the plane, such as the nose or the tip of the wing. The aircraft then flies through the lightning flash, which travels along the body, having chosen the path of least resistance.
How high can a 747 fly
35,105 ftEvery flight has its own ideal cruising altitude. This is the sweet spot where plane fly as fast as possible, but burn the least amount of fuel. A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft.
How high can you fly without a pressurized cabin
12,500 feetThe higher the maximum differential pressure, the closer to sea level the system can maintain the cabin. Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.
Do planes fly over 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.”
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.
How do planes slow down after landing
Larger turboprop aircraft have propellers that can be adjusted to produce rearward thrust after touchdown, rapidly slowing the aircraft. Commercial jet transport aircraft come to a halt through a combination of brakes, spoilers to increase wing drag and thrust reversers on the engines.
