Are Helicopters More Efficient At Higher Altitudes? Most helicopters use constant speed rotors so in practice, the angle of attack (the pitch of the blades) is the only variable. In order to maintain speed of the blades, the pilot, or a throttle governor, must increase power from the engine. Therefore, a helicopter uses more fuel
Why Does Water Boil At A Lower Temperature In Colorado? At elevated altitudes, any cooking that involves boiling or steaming generally requires compensation for lower temperatures because the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. The effect starts to become relevant at altitudes above approximately 2,000 feet
