Final answer:
An FSS provides essential advisories to pilots which include the active runway, wind details, hazards, traffic, aerodrome and weather conditions, and any special meteorological cautions for the safety of flight.
Step-by-step explanation:
An FSS, or Flight Service Station, provides Airport Advisory Services (AAS). These services include pertinent information that assists pilots during the arrival and departure phases of flight at uncontrolled aerodromes. When an aircraft first makes contact with a flight service specialist, they provide a range of important information for the safety of the flight. Here are the elements with the missing pieces filled in:
- Active or preferred runway;
- Wind direction and speed;
- Any hazard that warrants attention;
- VFR traffic;
- Special meteorological cautionary;
- Aerodrome conditions;
- Weather conditions;
- Additional information of interest for the safety of flight.
These advisories are essential for pilots to maneuver safely, especially in areas without controlled towers, as they depend on this information for situational awareness and making sound judgments.
