Aviation and Heavy Equipment Support Awareness
What the exam tests
Aviation and Heavy Equipment Support Awareness tests safe approach, communication, and spotter duties around helicopters, fixed-wing aircraft, and dozers. You are not expected to be a pilot or equipment operator; you are expected to keep the operation from becoming an accident.
Core rules
- Helicopter approach: wait for the pilot's signal, approach from the front or side in the pilot's field of view, stay low, secure loose gear, and never go near the tail rotor.
- Landing zone: clear debris, mark hazards, control people, and keep dust and smoke down; know the load and sling limits.
- Hand signals must be standardized and confirmed; if signal meaning is unclear, stop the operation.
- Spotter duties: maintain radio contact, watch the load, keep people out of the danger zone, and call hazards early.
- Heavy equipment: stay out of the blade's swing radius and blind spots, make eye contact, and use an agreed signal or radio protocol.
Worked example
A helicopter is landing on a ridge to drop supplies. A worker starts walking toward the aircraft from the rear. The spotter stops the movement and directs the worker to wait for the pilot's signal and approach from the side. The reasoning is tail-rotor and rotor-wash danger; the approach path must be in the pilot's view and controlled by the spotter.
Traps
Approaching a helicopter from the rear; walking behind a dozer; using unofficial hand signals; failing to secure loose equipment in rotor wash.
