What ramp hazards should be avoided during tow operations around a C-17?

• A. Obstructed walkways, hot brakes, hydraulic lines, unsecured debris, moving aircraft or vehicles in the path, and proximity to wing/engine areas.
• B. Only weather conditions.
• C. Non-operational radio systems.
• D. Parking brakes engaged only.

Answer: (D)

During tow operations, the ability of the aircraft to move freely is essential. If the parking brakes are engaged, the wheels won’t turn and the tow tractor may struggle to move the aircraft, risking damage to the braking system, towbar, or steering, and potentially causing an unexpected movement when braking releases. This direct interference with safe towability makes it the primary hazard to avoid in this scenario.

Weather conditions, non-operational radio systems, and other ramp factors are important for overall safety, but they are not the specific ramp hazard that directly prevents or governs the tow in the way that an engaged parking brake does.
