Here are some general guidelines on the amount of gas a helicopter needs:
* Small, single-engine helicopters: 5-10 gallons per hour of flight
* Medium-sized, twin-engine helicopters: 15-25 gallons per hour of flight
* Large, multi-engine helicopters: 30-50 gallons per hour of flight
These numbers are just estimates, and the actual amount of gas a helicopter needs may vary depending on the specific circumstances of the flight.
In addition to the amount of gas, helicopters also require a certain amount of oil to operate. The oil helps to lubricate the engine and other moving parts of the helicopter. The amount of oil a helicopter needs is typically about 1-2 quarts per hour of flight.
Here are some tips to help save gas when flying a helicopter:
* Fly at a slower speed. The faster a helicopter flies, the more gas it will use.
* Avoid flying in strong winds. Strong winds can make it more difficult for the helicopter to fly, which can lead to increased fuel consumption.
* Plan your flight carefully. By planning your flight carefully, you can avoid unnecessary flying time, which can help you save gas.
* Use a fuel-efficient helicopter. Some helicopters are more fuel-efficient than others. If you are looking to save gas, you may want to consider choosing a fuel-efficient helicopter.
