How is Low Key defined in altitude?

Low Key is defined as an altitude of 1,500 feet above ground level (AGL). This term is commonly used in aviation, particularly in the context of flight training and maneuvers. The Low Key altitude serves as a reference point for pilots during traffic patterns, especially when preparing for landing. At 1,500 feet AGL, pilots can assess the landing approach and align their aircraft for a safe descent toward the runway. Other altitudes mentioned in the choices are associated with different phases of flight or specific training exercises, but 1,500 feet AGL is the standard for Low Key, making it an essential reference for pilots during flight operations.
