Commercial jet planes fly in the lower stratosphere to avoid turbulence. The bottom of the stratosphere is approximately 10 kilometers or 33,000 feet above ground.
The stratosphere extends to approximately 50 kilometers or 31 miles above the Earth’s surface. The troposphere, the lowest layer of Earth’s atmosphere, is where almost all weather occurs. Jet planes fly through the troposphere to reach the stratosphere, where planes fly more smoothly and experience less weather interference. The height of the troposphere varies with altitude and season. The stratosphere is dry, with little water vapor. Therefore, a small amount of clouds are found in this layer compared to the troposphere.Learn More

The first successful airplane was created by the Wright Brothers, Wilbur and Orville. Airplanes are fixed-wing aircraft that use a 3-axis control and are propelled through the air using engines. Airplanes are commonly used for transportation, however, they are also used for research, recreation and military purposes. The engines located on the wings of the airplane create lift, overcome drag and allow the plane to travel forward.Full Answer >
An attitude indicator is a device used in aircraft to alert the pilot of the aircraft's orientation relative to Earth’s horizon. It works on the principle of gyroscopic rigidity in space. The fast-whirling rotor disk resists any attempt to interrupt its orientation. Hence, the gyro offers a steady horizontal reference against which the pitch and roll attitudes of the aircraft can be determined.Full Answer >
