'''Altitude''' is the measurement of the [[height]] of something relative to a given baseline, often the [[sea]] level and/or the seabed itself. It is vital to have an altitude measuring instrument in aicraft such as [[airplane]]s and [[helicopter]]s, for the pilots to be sure they avoid coming dangerously close to the ground and/or other terrain. Properly operating altimeters are also important for maining separation from other aircraft.
