How can a pilot identify the availability of HIWAS on a VFR Sectional chart?

• A. By looking for an "H" in the lower left corner of the NAVAID box.
• B. By checking the color of the identification box.
• C. By finding an "H" in the upper right corner of the identification box.
• D. By reviewing the altitude limits near the NAVAID.

Answer: (C)

The identification of HIWAS (Hazardous Inflight Weather Advisory Service) availability on a VFR Sectional chart is specifically indicated by a letter "H" located in the upper right corner of the NAVAID (Navigational Aid) identification box. This marking informs pilots that the NAVAID provides the HIWAS service, which delivers continuous broadcasts of hazardous weather information. Recognizing this indicator is crucial for pilots who wish to stay updated on any adverse weather conditions that could affect their flight operations. While the other options may provide additional information about the NAVAID or the chart itself, they do not specifically denote the availability of HIWAS. For instance, a different placement or symbol would not correctly convey the HIWAS service status, making the specific knowledge of the "H" in the upper right corner essential for pilots navigating using VFR Sectional charts.
