The attitude indicator (AI), also known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change. The miniature aircraft and horizon bar mimic the relationship of the aircraft relative to ...
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
In aviation, an electronic flight instrument system (EFIS) is a flight instrument display system in an aircraft cockpit that displays flight data electronically rather than electromechanically. An EFIS normally consists of a primary flight display (PFD), multi-function display (MFD), and an engine indicating and crew alerting system (EICAS ...
The aircraft entered the clouds 400 feet above the terrain. When the captain banked the plane to the left, the faulty INU sent erroneous data to his ADI, preventing the instrument from showing the aircraft was in a bank. The comparator alarm sounded repeatedly, which was an indication that the aircraft's two ADI displays were in disagreement. [7]
An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
The HSI illustrated here is a type designed for smaller airplanes and is the size of a standard 3 ¼-inch instrument. Airline and jet aircraft HSIs are larger and may include more display elements. The most modern HSI displays are electronic and often integrated with electronic flight instrument systems into so-called "glass cockpit" systems.

Avidyne was first to certify big glass for light GA with the 2003 launch of Entegra in Cirrus aircraft. This is considered a "first generation" big-glass system that integrates the six 3-inch instruments (6-pack) into a more usable package, along with an exceptionally reliable Air Data and Heading Reference System (ADAHRS) that replaces the "spinning mass" attitude and directional gyros.
