Under SHED BUSES OVRD, what condition must be met for the feature to operate?

• A. The airplane must be in flight
• B. The airplane must be on the ground and at least one generator operative
• C. All batteries must be on
• D. The APUs must be running

Answer: (B)

SHED BUSES OVERRIDE is a ground-mode power management function. It is designed to let you selectively keep certain buses powered while shedding nonessential ones, but only when there is a valid power source available on the ground. The feature will operate only if the airplane is on the ground and at least one generator is online. This ensures there is a live source to support the essential buses while the rest are shed. If the aircraft is airborne, or if no generator is providing power, the override isn’t used because flight requires a continuous, properly managed power distribution. The condition doesn’t require all batteries to be on, and it isn’t limited to APUs running—any operating generator meets the requirement.
