Turn and Slip Indicator (TSI)

Turn and Slip Indicator Introduction to Turn and Slip Indicator Turn and slip indicator consists of a turn indicator and a slip indicator Turn indicator has a horizontal rate gyro which measures rate of turn Horizontal rate gyroscope measures rate of turn around the vertical axis Turn indicator has lower rotor speed to use the property of precession Low RPM reduces rigidity and increase precession Slip indicator is a pendulous device indicating balance during turn Turn co-coordinator is an advanced form of turn and slip indicator Rate of Turn Indicator…

Artificial Horizon (AH)

Artificial Horizon Display of an Artificial Horizon Artificial horizon provides attitude of aircraft using a vertical axis gyro The gyro spin axis is maintained vertical to earth surface by gravity Gull wing etched on the outer glass moves with aircraft in pitch and roll The horizon image attached to an earth gyro maintains its orientation Nose up indication shows gull wing above the horizon Gull wing attached to outer gimbal moves down by a guide pin system Horizon bar attached to the inner gimbal retains its vertical position Artificial horizon…

Directional Gyro Indicator (DGI)

Directional Gyro Indicator Introduction to Directional Gyro Indicator DGI provides heading using a tied gyro with two degrees of freedom Spin axis of gyro is maintained in the yawing plane of the aircraft Gyro motor is located in the inner gimbal and readings seen on outer gimbal Outer gimbal can rotate through 360 deg Rotor axis, inner and outer gimbals are at right angles to each other In an air driven DGI, engine driven pump provides air jet to spin the rotor The outer gimbal turns whereas spin axis remains…
