What is the minimum safe operating distance for large aircraft like the B-747 or A-380?

The minimum safe operating distance for large aircraft such as the B-747 or A-380 is typically set at 200 feet. This distance is determined to minimize the risk of wake turbulence and jet blast, both of which can pose serious hazards to ground personnel and smaller vehicles operating in close proximity to large aircraft.

Wake turbulence is characterized by the vortices created by the wings of large planes, especially during takeoff and landing. These vortices can persist in the air for several minutes after the aircraft has passed, potentially endangering any smaller aircraft or persons operating too close. Jet blast, on the other hand, refers to the high-speed airflow generated by the engines of large jets, which can also affect any objects or personnel nearby if they are too close.

By maintaining a distance of 200 feet from these large aircraft, safety protocols help ensure that ground operations can be carried out without interference from these potentially dangerous environmental factors. This standard is critical for promoting safe behavior and preventing accidents in high-traffic zones like airports.
