Recently I have seen many questions regarding the difference between an attitude indicator and a turn coordinator, While they are both very important instruments on an airplane, they are different. So, without further a do, lets get into the differences.
Attitude Indicator
An attitude indicator or AI formerly 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 actual horizon. It is a gyroscopic instrument.
Turn Coordinator
In aviation, the turn and slip indicator also known as the turn and bank indicator and the turn coordinator variant are essentially two aircraft flight instruments in one device. One indicates the rate of turn, or the rate of change in the aircraft’s heading; the other part indicates whether the aircraft is in coordinated flight, showing the slip or skid of the turn. The slip indicator is actually an inclinometer that at rest displays the angle of the aircraft’s transverse axis with respect to horizontal, and in motion displays this angle as modified by the acceleration of the aircraft.
Below are pictures of a Attitude Indicator (1) and a Turn Coordinator (2)!
