The red HDG Warning Flag (3) becomes visible when the speed of the directional gyro is to low. Beware that there may occur compass failures that are not indicated by the HDG Warning Flag, so compare the indicated heading with the magnetic compass on a regular basis.

If the HSI is part of a slaved gyro system, the HDG Waring Flag also appears if the gyro has lost synchronization with the master. On a KCS55 this will happen, if a offset of more than 3 degrees is detected between earth magnetic field and the gyro indication. It also shows up, if the slaved gyro system is switch to manual mode.
