In procedure for grounding aircraft, what is the first step?

The procedure for grounding an aircraft is critical for ensuring safety by preventing static electricity accumulation and protecting personnel and equipment from potential hazards. The first step in this process is to ground the aircraft first before taking any further actions. This ensures that any static charge that might be present is safely dissipated to the ground, significantly reducing the risk of sparks or electrical discharge. Grounding provides a direct path for any excess charge to flow away from the aircraft, creating a safer environment for personnel who may be working around it.

This initial grounding step is essential because if any subsequent actions occur without grounding — such as opening doors, switching off instruments, or powering up charging stations — it may increase the likelihood of electrical shocks or damage caused by discharges. Consequently, prioritizing grounding establishes a baseline for safety that must be adhered to throughout all operations involving the aircraft.
