How does an aircraft attitude indicator work?
The Attitude Indicator shows rotation about both the longitudinal axis to indicate the degree of bank, and about the lateral axis to indicate pitch (nose up, level or nose down). Once powered up, the indicator is maintain in a fixed position no matter what the aircraft attitude may be.
How does the turn coordinator work?
The turn indicator is a gyroscopic instrument that works on the principle of precession. In the turn coordinator, the gyro is canted 30 degrees from the horizontal so it responds to roll as well as yaw. The display contains hash marks for the pilot’s reference during a turn.
What does an artificial horizon indicate?
: a gyroscopic flight instrument designed to indicate aircraft attitude with respect to the true horizon.
What is another name for artificial horizon?
the bubble in a sextant or octant for aerial use. Also called flight indicator, gyro horizon .
What causes an artificial horizon to make a wrong turn?
Turning and acceleration errors in the artificial horizon gyroscope are caused by lateral acceleration in turns and by the aircraft’s acceleration and deceleration forces that induce a false position indication of the gyroscope’s vertical axis.
What causes acceleration errors in the artificial horizon gyroscope?
Turning and acceleration errors in the artificial horizon gyroscope are caused by lateral acceleration in turns and by the aircraft’s acceleration and deceleration forces that induce a false position indication of the gyroscope’s vertical axis. Note: Remember, the artificial horizon is an earth gyroscope with its spin axis in the earth vertical.”
How is the rotor of an artificial horizon mounted?
The rotor, mounted in a sealed housing, spins in a horizontal plane about the vertical axis. The housing pivots about the lateral axis on a gimbal, which in turn is free to pivot about the longitudinal axis. The instrument case is the third gimbal necessary for universal mounting.
Where does the air come from for the artificial horizon?
Air is sucked through the filter, then through passages in the rear pivot and inner gimbal ring, then into the housing, where it is directed against the rotor vanes through two openings on opposite sides of the rotor.
