As it happens, feet is a convenient unit for altitude because 1000 feet is a distance that is safely usable for IFR separation. In metric-using areas, of which there are very few, the “equivalent” is 300 meters. … ATC and Pilots don’t care if it’s feet, meters, or whatzits.
Do you need your feet to fly a plane?
Flying an airplane, like driving a car, requires using your hands and your feet. … But airplanes also have two pedals that direct the rudder, which is critical in controlling the aircraft in turns or a tricky crosswind.
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.
Can planes fly at 100000 feet?
A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it. … A: During certification testing, airplanes are flown above the certified ceiling, but the performance is limited.
Do planes fly at 50000 feet?
Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. … However, many light aircraft have to cruise below 10,000 feet because they don’t have the luxury of pressurized cabins like jetliners.
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.” …
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?
When lightning hits an aircraft, it arcs through the fuselage, from the wings and nose, and exits through the tail. All wires onboard are grounded or isolated away from the body, and the electric current passes through the conductive outer shell of the aircraft.
What is the highest feet a plane can fly?
Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a ‘service ceiling. ‘ For example, for the double-decker Airbus A380 ‘superjumbo’ quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 ‘Dreamliner,’ it is 43,100 feet.
How many feet up is space?
In the US, “space” begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet. “Low Earth Orbit” (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).
How high can a 747 fly?
The Boeing 747–8 has a ceiling slightly over 43,000 feet MSL (above mean sea level). NOTE: The FAA levies strict rules and tests that aircraft manufactures have to abide by and conduct if an airliner is to fly above 40,000 feet.
What is the highest flying bird?
The world’s highest flying bird is an Asian goose that can fly up and over the Himalaya in only about eight hours, a new study finds.
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.
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.
Is there turbulence at 50000 feet?
A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.
