Do vehicles within 20 feet of aircraft require a parking emergency brake?

1. true

2. false

The correct answer is: false

The answer is true: vehicles within 20 feet of an aircraft are required to have their parking emergency brake engaged. This is a critical safety measure intended to prevent accidental movement of vehicles in proximity to aircraft, which could result in damaging collisions or other dangerous situations. When vehicles are parked near aircraft, the risk of inertial movement due to wind, engine thrust, or operator error increases. Requiring the parking brakes to be engaged ensures that the vehicles remain stationary while aircraft operations are being conducted. Although the other options may seem plausible, they do not uphold the safety protocols necessary in aviation environments. Engaging the parking emergency brake is a standard operating procedure that contributes to maintaining the overall safety of the airfield and surrounding areas.
