A helicopter blade works the same way as a wing on a fixed wing aircraft. The air flowing faster over the top of the airfoil generates lift. When a helicopter flies at a high altitude the air gets thinner. Because the air is thinner, more pitch on the blades is needed to keep the helicopter in the air. When too much pitch is on the blades the blades stall, air moves past the bottom of the blade and creates a vortex behind the top of the blade. All lift is lost and you lose altitude.
What else can I help you with?
Why do rescue helicopters have a difficult time flying at altitudes above 6000 meters?
Because the air is thinner there
Why do helicopters have a difficult time flying above 6000 meters?
Helicopters struggle at high altitudes due to reduced air density, which decreases lift generation, engine performance, and rotor efficiency. Furthermore, the lower air pressure makes it harder to control the aircraft, affecting its stability and responsiveness.
What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying altitude above 6000 m?
An inverse relationship.
Which instrument is used for measuring altitudes in aircraft?
An altimeter is the instrument that is used for measuring altitudes in aircraft. It indicates the height above a reference point, typically sea level, and provides crucial information for pilots to maintain safe flying altitudes.
Can helicopters fly in the stratosphere?
Helicopters are typically designed to fly in the troposphere, which is closer to the Earth's surface. The stratosphere begins at around 10 kilometers above sea level, and helicopters lack the necessary design and power to operate efficiently at that altitude.

What precautions do pilots have to take if they fly above 45000 m?
Precautions when flying at high altitudes would be a pressure suit and oxygen /masks. But civilian flights do not ascend over 43,000 feet in the US.
What animal lives at the highest altitude?
The bar-headed goose holds the record for the highest altitude living bird, as it is capable of flying at altitudes of over 29,000 feet. Among mammals, the Himalayan marmot is often found at high altitudes above 15,000 feet in the Himalayas and Tibet.
What is medium altitude?
Medium altitude refers to the range of altitudes typically between 2,000 and 7,000 meters above sea level. It is a zone in the atmosphere where weather patterns, atmospheric conditions, and cloud formations can vary significantly. Aircraft flying at medium altitudes usually experience smoother air compared to lower altitudes.
How high can helicopters fly?
The vast majority of helicopters cannot fly above around 8,000 ft. The SA.315 Lama however set a record by flying at 41,000 ft. It regularly operates at over 20,000 ft. It is the worlds highest flying helicopter. In India it is called the Chetak.Helicopters themselves aren't the limiting factor in their ceiling. Above 12,000 feet, pilot and crew need to be on supplemental oxygen. That said, a helicopter's VTOL ability is of little value at altitude so their role means they stay within a few thousand feet AGL.
Why planes often fly at least 10 km from the ground?
Planes often fly at least 10 km from the ground to avoid turbulence and weather disturbances that are more prevalent at lower altitudes. At higher altitudes, the air is thinner, which reduces drag and improves fuel efficiency. Additionally, flying at cruising altitudes allows aircraft to stay above most commercial air traffic, enhancing safety and efficiency in air travel.
What blows at very high speeds at altitudes above 12km?
jet stream
Which city in the India located above the sea level at highest altitudes?
ladakh
Why don't birds fly above altitudes of 50 miles or higher?
Oxygen
