What is the ingestion zone defined for all American aircraft?

The ingestion zone for all American aircraft is defined as 15 feet. This specification is important because it establishes a safety buffer around the aircraft engines, where the risk of ingesting foreign objects is significant. By adhering to this zone, ground personnel can take necessary precautions to avoid accidents or damage to the aircraft's engines. The ingestion zone helps to ensure safety in airport operations, particularly around active runways where aircraft are taxiing, taking off, or landing. Recognizing and respecting the boundaries of this zone is crucial for maintaining safe and efficient ground handling practices.
