Final answer:
The ingestion zone at idle power for an Airbus aircraft engine typically extends a variable distance in front of the engine inlet, which can be several feet to over 15 feet, depending on the engine and aircraft model.
Step-by-step explanation:
The ingestion zone of an aircraft, such as an Airbus, at idle power is a specific area in front of the engine inlet where there is a risk of foreign objects being ingested into the engine. The actual radius of this zone can vary based on the engine's size, design, and the specific model of the aircraft. For large commercial jet engines, this zone can extend anywhere from a few feet to 15 feet or more in front of the engine. As an Airbus could refer to any number of aircraft models, the precise radius would be detailed in the Aircraft Operations Manual (AOM) or a similar technical document. It's important for ground personnel and equipment to stay clear of this area to prevent damage to the aircraft and ensure safety.
