It depends on the weather condition and the pilot controllability...
When there is no gust wind and the pilot got good control over the helicopter then it can float or stand in the air for longer time
A kite can fly without having wings. It is flown using a string that controls its movement and allows it to soar through the air.
It was based on the dragonfly's ability to hover in the middle of the air without moving.
Rapid air movement
It is hard for a helicopter to fly at altitudes above 6000m due to the thin air at high altitudes, which reduces the lift generated by the rotor blades. As the air gets thinner, the helicopter's engine struggles to maintain power and lift. Additionally, the helicopter's performance is affected by the decreased air density, making it challenging to maintain stable flight.

An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.
An airplane has fixed wings to provide lift to keep it in the air and engines (propeller or jet) to provide thrust for forward movement.A helicopter has rotary wings that when turned by the engine provide both lift to keep it in the air and thrust for movement in any horizontal direction.
When a helicopter flies close to a water surface, the air below the helicopter is disturbed by the movement of the rotor blades. This disturbance can affect the lift generated by the rotor blades, leading to a loss of altitude due to reduced lift. This phenomenon is known as "ground effect."
if you have a helicopter or a military grade hoover craft Hot-air balloons and gliders can be used
The helicopter blades push air down. By Newton's third law, the air pushes the helicopter upward.
The turning rotor of a helicopter creates lift by pushing air downwards, which generates an upward force that allows the helicopter to move upwards. This lift is created due to the rotor blades producing a pressure difference between the top and bottom surfaces as they rotate through the air. The angle of attack of the rotor blades can be adjusted to control the amount of lift produced and therefore the upward movement of the helicopter.
