The Aircraft Instrument System

In order for a pilot to carry out a flight operation with as much safety and efficiency as possible, they must be constantly fed accurate information regarding flight parameters and system conditions. Even in the early days of powered flight, instruments such as tachometers, anemometers, and stopwatches were used to track engine operations, and technology has only exploded since. Nowadays, pilots and flight crews have easy access to numerous data points and aircraft conditions that range from the altitude the aircraft is flying at to surrounding weather. 

As pilots remain in the cockpit of the aircraft for the entire flight, all information is fed straight to them and displayed in an easily accessible and viewable area. Whether the aircraft is older or more modern, most flight instruments and data displays are situated on panels that are situated below and around the windshield. For older aircraft that feature analog instrument installations, a wide variety of gauges and dials may be placed around the panels, each of which offers a reading on a specific condition or system. In the modern day, most gauges and dials have been replaced with computer-controlled digital interfaces and flat-panel displays. To make consuming necessary information easier, these modern displays will often prioritize and combine messaging so that pilots do not need to scan individual dials during flight.

Almost every instrument that belongs to the aircraft instrument system will come in two parts, one of which senses conditions and another that displays the garnered reading. The first instrument element is known as the sensor, and it may use anything from diaphragms to resistors to conduct a particular reading, the chosen method varying on what is being gauged. If the sensor is remotely placed, it will need to convey information to the indicator through wiring, pneumatic lines, or other means. In recent years, digital data buses have proven to be the most efficient options for data transfer as the signals of multiple sensors can be individually encoded and transferred on the same wires so that the overall amount of wiring is reduced in the aircraft.

While an older aircraft instrument system is mostly unchangeable with dials being a permanent fixture in the area that they are installed, digital displays offer more possibilities for customization as pilots can choose what information they need to see. As the two options are installed, operated, and maintained differently, it is essential that a pilot or technician familiarizes themselves with the possible instruments and systems they may come across.
