What should ATC provide to VFR traffic to maintain safety?

To maintain safety for VFR (Visual Flight Rules) traffic, ATC (Air Traffic Control) should provide information and coordination. This function is essential because VFR pilots are responsible for maintaining their own separation from other aircraft and obstacles. By providing information such as traffic advisories, weather updates, and situational awareness, ATC helps pilots make informed decisions about their flight paths and avoid conflicts with other aircraft.

Coordination between ATC and VFR traffic ensures that pilots receive relevant information that might affect their flight, such as nearby IFR (Instrument Flight Rules) operations or temporary flight restrictions. This collaborative approach enhances safety in the airspace, allowing VFR pilots to navigate more effectively while staying aware of their operational environment.

The other choices may not fully contribute to maintaining safety for VFR traffic. For instance, while flight plan filing assistance can be helpful, it is not a direct safety measure during flight. Full traffic separation is primarily applicable to IFR operations rather than VFR, where pilots are responsible for their own separation. Lastly, access to restricted airspace is typically a clearance or authorization that does not pertain directly to the safety of VFR traffic in general operations.
