If a helicopter runs out of fuel, it can glide to the ground using a technique called autorotation.
Understanding Autorotation
Autorotation allows a helicopter to land safely even without engine power. Here's how it works:
- Descending Airflow: As the helicopter descends, air flows upwards through the main rotor.
- Rotor Blades Spin: This upward airflow causes the rotor blades to spin, similar to a windmill.
- Controlled Descent: The pilot controls the rotor speed and descent rate to ensure a safe landing.
According to provided information, a helicopter is able to "glide to the ground" using autorotation if the engine fails.
How to Avoid Fuel Exhaustion
The best way to handle the situation described above is to ensure it doesn't happen in the first place.
- Flight Planning: Careful flight planning is crucial to avoid running out of fuel.
- Fuel Monitoring: Pilots must continuously monitor their fuel levels during flight.
- Reserve Fuel: Always carry enough reserve fuel to account for unexpected delays or changes in flight conditions.
