The distance from the edge of the parking ramp to a mobile obstacle is what?

The correct distance from the edge of the parking ramp to a mobile obstacle is 50 feet. This distance is vital for maintaining safety and allowing for sufficient reaction time when maneuvering vehicles near potential hazards. A spacing of 50 feet provides enough clearance to prevent accidents, ensuring that mobile obstacles do not pose a risk during ground operations at the airfield.

This distance is commonly taught as part of airfield driving training because it balances safety with operational efficiency. Recognizing and adhering to this guideline can help prevent collisions and ensure that all personnel safely navigate around the airfield environment. Other distances, such as 25, 100, or 200 feet, may not effectively provide the same level of safety or could be impractical in various scenarios, which is why they are not the preferred measurements in this context.
