For the ILS approach into San Jose Costa Rica, the required visibility is 900 meters. In which document can you find a conversion table for this value?

• A. AIM
• B. AIM Supplement
• C. FOM
• D. Jeppesen Solutions Manual

Answer: (C)

The key idea is knowing where an operator keeps the official unit-conversion reference used for planning and flying. The best place to find a conversion table for visibility values (like 900 meters) is the Flight Operations Manual. This document contains the airline’s approved conversions between visibility and RVR, and how those minima are applied in daily operations and approach procedures. It is the source pilots and dispatch use for converting published minima into the units used in the cockpit and in operational planning. The Aeronautical Information Manual provides general regulatory guidance on weather and units, but it does not house the operator-specific conversion table used for day-to-day missions. The AIM Supplement updates AIM content and isn’t the primary reference for these operator-specific conversions. Jeppesen Solutions Manual covers charting and Jeppesen-specific procedures, not the official conversion tables your airline uses.
