• ALL Flags in view: Notes:

  All five flags in-view indicates a power loss. The power loss can be caused by a power failure to the indicator or an internal power supply in the ADI.

  
  

  1.Check for power at cannon plug on back of ADI (D243 PIN 20).
  
  2.If power is available at the cannon plug then replace the indicator.
  
  3.If power is not available at the cannon plug then trouble shoot power source.

  Additional Tips:

  The Captains ADI receives power from the 115v AC STBY Bus. If this bus is not power you will get all flags in-view on the Captains ADI and HSI, and the F/O’s RDDMI. If this happens check the standby power switch on the P5 panel. Lift the cap and ensure that the switch is fully in the "Auto" position. This switch has a tendency to hang up between Off and Auto when the cap is closed.
