This lesson enables trainees to perform a full pre-operation walkaround of a Ground Power Unit (GPU). They learn to identify damage, leaks, and electrical faults, ensuring the equipment is safe and operational before aircraft servicing.
Damaged or obstructed surroundings
Triggers a safety cue, reinforcing the need to keep the area clear of FOD and obstacles to prevent accidents before operation.
