In summary, the conversation discusses the concept of how a helicopter is able to remain stationary in the air, as opposed to a regular airplane which needs to constantly move forward in order to stay aloft. The conversation also touches on the idea of how a helicopter can travel parallel to the ground. The person speaking suggests doing research and reading about helicopters before asking specific questions on the topic.

Why does a regular airplane not fall out of the sky? How can it just travel along parallel to the ground?

Welcome to the PF.Abu Bakar Zahid said:
We prefer that you do some reading and research first, before asking broad questions like that. Please read about helicopters at Wikipedia and other websites that you can find with Google, and start a new thread with any *specific* questions you have about that reading. We are very willing to help you learn, but you need to put some effort in too, okay? Thanks.

1. How does a helicopter's rotor help it stay still in the air?
The rotor of a helicopter creates lift by spinning at a high speed, which allows the helicopter to remain suspended in the air.
2. What is the role of the tail rotor in keeping a helicopter still in the air?
The tail rotor of a helicopter is responsible for countering the torque produced by the main rotor, which helps the helicopter stay balanced and still in the air.
3. Can a helicopter stay still in the air without using its engines?
Yes, a helicopter can stay still in the air without using its engines by making use of autorotation. This technique allows the rotor to continue spinning even if the engines are turned off, providing enough lift to keep the helicopter suspended.
4. How do pilots control the hovering position of a helicopter?
Pilots control the hovering position of a helicopter by adjusting the angle and pitch of the rotor blades. This changes the amount of lift and thrust produced, allowing the helicopter to move up, down, or stay still in the air.
5. What are the factors that affect a helicopter's ability to stay still in the air?
The main factors that affect a helicopter's ability to stay still in the air are wind conditions, the weight of the helicopter, and the skill of the pilot in controlling the helicopter's movements.
