If the ADG is deployed and power is re-established during flight what must you do?

• A. Stow the ADG handle and push the "PWR XFER OVERRIDE" button, so that power can be reestablished to the Essential Bus
• B. Leave the ADG deployed and do nothing
• C. Turn off all APUs
• D. Reset the GPU

Answer: (A)

When the ADG has been used and power returns, you need to return the electrical system to normal by transferring the power source to the Essential Bus. Stowing the ADG handle and pressing the Power Transfer Override reestablishes power to the Essential Bus from the normal sources, ensuring the aircraft’s critical systems stay powered correctly and without conflicts from the temporary deployed generator. Leaving the ADG deployed or taking unnecessary steps like turning off APUs or resetting the GPU can keep the system out of its proper configuration and may cause electrical conditions that aren’t desired.
