there can be any number of reasons for that.

Why does a helicopter lose altitude when flying over a water surface?
A helicopter needs a solid surface to fly over.
Can a helicopter reach a plane's altitude?
A helicopter cannot reach a plane's altitude because it does not have much lift. No, the air is to thin high up for a helicopter to sustain flight.
How do you land a hellicopter in saints row 3?
Just slowly keep tapping the Ctrl key to lose altitude. The helicopter will stablilise after each press, and can easily be landed without damaging it.
What would be data for collecting data in a helicopter experiment?
The helicopter's altitude, distance traveled, speed/rate of travel, etc.
When did amelia earhart break the altitude record?
She hit an altitude record for an autogiro, a forerunner of a helicopter- at l8,4l5 feet, this was computed from theodolite observations from the ground.
What is the average altitude a helicopter may fly at?
Helicopters fly somewhat close to the ground. They fly near the troposphere. They fly at a lower altitude than planes.
Why can't rescue helicopters fly in low air pressure?
I've never heard that. However, helicopters are limited to the altitude that they can hover, which would limit a Rescue helicopter from picking up a stranded mountain climber. In the high altitude, the air is "thinner" which means the air pressure is less. This limits the effiency of the rotor blades. However, usually the first indication of a problem is when a helicopter tries to hover at high altitude and the tail rotor looses it thurst and the helicopter goes into an uncontrolled spin. This was common with the Bell Model 206B. Even though a helicopter may be limited to the altitude at which it can hover, that does not mean it can't fly at that altitude. If a helicopter maintains a high forward air speed, it can still fly over mountains; its only when it stops and hovers that it may have problems.
Why do helicopters have a difficult time flying at altitudes above 6000 m?
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.
How does a helicopter turn?
By increasing or decreasing the speed of the tail rotors. This unbalances the torques acting on the helicopter and causes it to spin.
What to do if you lose a helicopter blade off of a transformers blackout toy?
Find it
What causes altitude sickness?
Altitude sickness is caused by changes in the distribution of oxygen and pressure. The symptoms of altitude sickness resemble those of a cold.
How does helicopter's work?
the engine inside causes the propeler to spin
