Which indications are required to be safe to pushback?

Explanation:
Pushing back safely hinges on three confirming indications: tow authorization, released parking brakes, and steering disengaged. The green towing light being on shows ground crew authorization for towing, meaning the aircraft is cleared to move with a tug. The parking brake indicator being extinguished means the parking brake is released, so the aircraft isn’t resisting movement. The STEER OFF EICAS message tells you nose-wheel steering is deactivated for the pushback, preventing steering inputs from the cockpit from fighting the tow tractor or causing unintended nose-wheel movement. When all three are present—tow light on, parking brake off, and steering off—the aircraft is in the proper state to begin pushback. If any of these aren’t true, pushback would be unsafe: the tow signal isn’t active, brakes could hold the aircraft, or steering could interfere with the maneuver.
