Beechcraft 1900D — V Speeds Reference

This document serves as an Aircrew Quick Reference Guide to METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast) codes, providing essential information for aircrews to decode weather reports efficiently. It outlines how to interpret various weather conditions, including visibility, wind speed, temperature, and cloud coverage, which are crucial for flight safety and operational planning. The guide emphasizes the importance of understanding these codes to assess flight safety hazards and make informed decisions based on current and forecasted weather conditions. It is intended for use by military aircrews and includes detailed explanations of the codes, examples, and conversion tables for temperature, visibility, and pressure.

• METAR reports provide current weather observations, while TAF reports offer forecasts for specific periods.
• Wind speed is reported in knots, with gusts indicated by a 'G' followed by the gust speed.
• Visibility is measured in statute miles in METAR and meters in TAF, with specific codes for conditions like mist or fog.
• Temperature and dewpoint are given in degrees Celsius, with 'M' indicating negative values.
• Altimeter settings are crucial for maintaining proper altitude and are reported in inches of mercury.
