Why can't airplanes climb higher before flying over residential areas?

Airplanes at this altitude (5,670 feet above sea level) don’t perform as well as they do at lower elevations. This means they can’t climb as quickly because their wings, engines and propellers are less efficient in the thin air. The planes create more noise because they are forced into a more shallow climb angle. At lower elevations, pilots typically use the lowest power setting possible for take off, reducing engine wear, saving fuel and creating less noise. At a high-altitude airport like ours, pilots must use a higher power setting for safety reasons; plane engines don’t provide as much thrust at this elevation. The result is more noise because planes must fly closer to the ground for longer periods; nothing can change this physical fact. Call us at 303-271-4850 for more information.
