Which statement describes how AH-64E cockpit avionics are powered during faults?

• A. Essential systems remain powered during faults, while non-essential may be shed to preserve power.
• B. All avionics stay powered as on, regardless of faults.
• C. Non-essential systems stay powered while essential may be shed.
• D. Only flight control computers stay powered.

Answer: (A)

During faults, cockpit power is managed by prioritizing what keeps the helicopter controllable and the crew informed. Essential systems stay energized to preserve flight safety, while non-essential loads may be shed to conserve power. In the AH-64E, this means you keep the critical cockpit avionics—such as flight control computers, attitude/heading information, and primary displays—powered, even if electrical power is limited. Non-essential equipment, like some mission sensors or non-critical systems, can be turned off to ensure the essential avionics continue to operate. That’s why the other statements don’t fit. It isn’t true that all avionics stay powered regardless of faults; there’s deliberate load shedding to protect essential functions. It isn’t correct that non-essential stays powered while essential may be shed, because the priority is to preserve essential, flight-critical systems. And it isn’t accurate that only flight control computers stay powered, since other essential cockpit avionics and displays are also kept powered to maintain situational awareness and safe control.
