Grounding on the ramp is used to dissipate static electricity that can build up on an aircraft while it’s parked outdoors. Outdoor conditions and handling can generate charge, and if fueling or servicing is done, a spark could ignite fuel vapors. Because any aircraft, regardless of type, is at risk, every aircraft should be grounded to provide a safe, continuous path to earth. That’s why the best choice is that all aircraft must be grounded. The other options would either leave some aircraft ungrounded or wrongly restrict grounding to certain categories, which isn’t acceptable for safety.
