altitude
A segment that connects a vertex of a triangle to the opposite side so that it is perpendicular to that side
Altitude refers to the distance above sea level or ground level at which an object, such as an airplane, mountain or satellite, is located. It is measured in units of feet or meters. Altitude is an important concept in aviation, where pilots must maintain a particular altitude to ensure safe and efficient flight.
There are several types of altitude that are commonly used. These include:
1. True Altitude: This is the actual height of an object above mean sea level. It is typically measured using a altimeter, which takes into account changes in atmospheric pressure.
2. Indicated Altitude: This is the altitude indicated on an altimeter, which does not take into account local atmospheric conditions. It is used as a reference point for pilots.
3. Pressure Altitude: This is the altitude relative to a standard pressure level of 29.92 inches of mercury. It is used as a reference point for aircraft performance.
4. Density Altitude: This is the pressure altitude adjusted for variations in temperature and humidity. It is used to calculate aircraft performance in hot and high conditions, where the air is less dense.
Understanding altitude is essential for pilots, air traffic controllers, and other professionals working in aviation. It is also important for hikers, mountaineers, and other outdoor enthusiasts who need to navigate mountainous terrain.
