Flight instruments in aircraft provide pilots with vital information about the condition and performance of the aircraft. The complexity of the instruments depends on the type of aircraft and its intended use. Pilots use a combination of visual cues and instrumentation during flight, but must obtain supplemental certification to fly an aircraft with instrumentation only. Larger commercial and military aircraft have more technologically advanced instruments. Flight instruments are typically arranged in a way that provides the pilot with a seamless view of the gauges and indicators. Electronic flight instruments are becoming more common.
Flight instruments are the gauges, indicators, and warning systems in the cockpit of an airplane. This equipment helps the pilot fly the aircraft safely under a variety of flight conditions, day or night. Instruments convey vital information about the systems, condition and performance of the aircraft throughout the flight, and it is possible, and sometimes necessary, for a pilot to operate the aircraft based solely on the instruments.
The variety and complexity of an aircraft’s flight instruments depend on the type of aircraft and its intended use. Single propeller aircraft generally require less sophisticated instrumentation than twin propeller aircraft. While most aircraft—planes and helicopters—require an altimeter, airspeed indicator, and heading indicator, there are certain types of aircraft, such as homemade experimental aircraft, ultralights, gliders, and others, that can fly completely free of the reliance on flight instruments in favorable conditions. weather conditions. Many pilots, private, commercial, and military, also rely on radio navigation aids such as very high frequency omnidirectional range finders (VORs) to help maintain course.
In the United States, there are two sets of regulations that govern flight: the visual flight rules and the instrument flight rules. The former govern the operation of the aircraft when the pilot flies primarily with visual cues, while the latter govern instances where pilots choose or are forced to use only their instrumentation. In practice, pilots use a combination of visual cues and instrumentation during flight, but a pilot must obtain supplemental certification to fly an aircraft with instrumentation only. Additional training includes extended flight hours with an emphasis on instrument flying. The certification is issued by the aviation authority of the country in which the pilot resides.
For larger commercial aircraft such as jets and military aircraft, flight instruments are much more technologically advanced. Electronic warning displays allow fighter pilots to keep their eyes on the sky, displaying the most pertinent flight data on a transparent projection that is always in the pilot’s line of sight. Sophisticated navigation equipment, including a computer-updated compass, automated course-keeping computer, and other instruments, is used on large commercial aircraft to allow the flight crew to better control the aircraft.
Flight instruments are typically arranged within the aircraft cockpit in a way that provides the pilot with a seamless, flowing view of the gauges and indicators. Traditionally, flight instrumentation is displayed in analog or digital format, but with the increasing computerization of flight controls, instruments are becoming fully electronic. Electronic flight instruments differ from digital instruments in that a digital readout displays data from the same sensor that analog instruments use. Electronic instruments, on the other hand, use computer processors instead of mechanical devices to collect and transfer flight data.
