groundpassing

Groundpassing refers to a maneuver in aviation where an aircraft flies at a low altitude over the ground. This action is typically performed during training or for specific operational purposes. In some training contexts, groundpassing is used to practice low-altitude flight control and awareness of the surrounding environment. It can also be a component of emergency procedures, such as practicing engine-out approaches or go-arounds.

For military aviation, groundpassing, often termed low-level flight or terrain-following, is a crucial tactic for evading radar detection and delivering ordnance. This requires specialized aircraft and highly skilled pilots trained to navigate complex terrain at high speeds while maintaining a safe distance from the ground. Civilian applications of groundpassing are generally limited and highly regulated due to safety concerns. Unauthorized groundpassing is a violation of aviation regulations and can result in severe penalties.
