Are helicopters more efficient at higher altitudes?
Most helicopters use constant speed rotors so in practice, the angle of attack (the pitch of the blades) is the only variable. In order to maintain speed of the blades, the pilot, or a throttle governor, must increase power from the engine. Therefore, a helicopter uses more fuel as it’s altitude increases.
Does altitude affect helicopters?
This means a higher density altitude and less helicopter performance. Altitude – As altitude increases, the air becomes thinner or less dense. This is because the atmospheric pressure acting on a given volume of air is less, allowing the air molecules to move further apart.
Can planes fly higher than helicopters?
An airplane can fly higher than a helicopter because air planes have horizontal turbines or rotors. a helicopter has propellers that push on air. if said helo get to high.. the air gets to thin for the helicopter to “push” on the air so therefore it cannot fly any higher.
Why do helicopters fly lower than airplanes?
Due to safety regulations, airplanes must stay at a certain altitude above the ground at all times unless over open water or while landing. Helicopters have a little more freedom and are able to stay at a lower altitude. Airplanes are unable to fly in low visibility weather.
Can a helicopter fly to the top of Mount Everest?
Choppers reportedly also flew ropes and other equipment to climbers stranded above the Khumbu icefall, which also sits nearly 18,000 feet above sea level. And helicopters have actually made it even to the peak of Everest before, the first time in 2005.
Why do helicopters struggle at high altitude?
As the helicopter climbs in altitude, the air gets thinner, requiring the blades to work harder to generate the same amount of lift. Most helicopter pilots consider 10,000 feet the upper limit of the ideal altitude for flying.
Is flying a helicopter harder than a plane?
Since helicopters are generally harder to fly than airplanes, they also are more dangerous to fly. Overall, helicopter crashes are more frequent than airplanes, as well. Helicopters crash about 35 percent more often per hour in the air than your average aircraft.
Can helicopters fight jets?
‘A well equipped attack helicopter flown by a trained crew will defeat most fighter airplanes in 1v1 air combat, should the fighter be foolish enough to drop down to try and engage,’ Nick Lappos, Technical Fellow Emeritus at Sikorsky and former U.S. Army AH-1 Cobra attack helicopter pilot, said on Quora.
How do you poop on Mt Everest?
Short answer: make it quick. In camp one and two on Mount Everest, there are poop buckets inside tents that provide a relatively safe environment to do what you’ve got to do. These buckets are brought down to the village by sherpas to be emptied there.
How many dead bodies are on top of Mount Everest?
200
There have been over 200 climbing deaths on Mount Everest. Many of the bodies remain to serve as a grave reminder for those who follow. PRAKASH MATHEMA / Stringer / Getty ImagesThe general view of the Mount Everest range from Tengboche some 300 kilometers north-east of Kathmandu.
Can helicopters fly across the ocean?
A helicopter can fly across the Atlantic – and this has been achieved several times. The first transatlantic helicopter flight took place in 1952. The first non-stop transatlantic helicopter flight took place in 1967.
