Final answer:
The Flight Service Station is located on the airport and houses the Control Tower. The primary frequency is used by the Control Tower for communication. ATIS broadcasts important airport information, and VFR advisories are provided when ATIS is unavailable.
Step-by-step explanation:
The Flight Service Station is responsible for providing essential flight information and services to pilots. It is located on the airport and houses the Control Tower. The Control Tower is the building from where air traffic controllers monitor and direct aircraft movements within the airport's airspace. The primary frequency is the main radio frequency used by the Control Tower to communicate with pilots.
- ATIS - Automated Terminal Information System - broadcasts weather information, runway conditions, and other relevant airport information to pilots. It is available on a specific frequency.
- Field elevation is the height above sea level of the airport's landing area.
- L = Lighting indicates the presence of lighting systems at the airport.
- 72 = runway length indicates the length of the runway in hundreds of feet. For example, 72 would mean a runway length of 7200 feet.
- (68) usable length refers to the portion of the runway that can be used for takeoff and landing.
- VFR advisory is a notice provided to Visual Flight Rules (VFR) pilots when the ATIS is not available. It aims to provide them with relevant information for operating safely in the airport's vicinity.
