UH60 Crew Chief Practice Test

During engine start, the key safety rule is to keep ground personnel away from parts of the aircraft where unintended interaction could cause harm or accidental operation. While hazards like hot exhaust, rotor arcs, inlets, and moving components are real and require exclusion zones, this item highlights the cockpit area as the primary concern for ground crew. The cockpit dash panel houses critical flight controls and electrical systems; if a ground crew member touches or bumps controls during startup, it could trigger unwanted actions or electrical issues. Therefore, the cockpit dash panel is identified as the main area to avoid for safe engine start operations. The other areas listed are important hazards in general, but the cockpit area is the focus here due to the potential for inadvertent control engagement.
