Instrument navigation is a method used by pilots and mariners to determine their position and navigate safely using instruments rather than relying on visual cues. This technique is essential in poor weather conditions or at night when visibility is low. Instruments like GPS, compasses, and altimeters provide critical information about location, speed, and altitude. In aviation, instrument navigation involves following specific flight paths and procedures outlined in air traffic control instructions. Similarly, in maritime navigation, sailors use tools like radar and charts to plot their course. Both methods ensure safe and efficient travel across vast distances.
