📚 Understanding TAF Forecasts

Terminal Aerodrome Forecast (TAF) provides detailed weather forecasts specifically for aviation operations. Our system translates complex meteorological codes into plain English to help pilots of all experience levels understand forecasted conditions.

What TAF Includes:

• Wind direction, speed, and gusts
• Visibility in statute miles or kilometers
• Weather phenomena (rain, snow, fog, thunderstorms)
• Cloud coverage types and altitudes
• Forecast changes with timing
• Flight rules categories (VFR/IFR)

Change Indicators Explained:

• BASE - Main forecast conditions
• FM - Permanent change from specific time
• BECMG - Gradual change over 2-4 hours
• TEMPO - Temporary changes (less than 1 hour)
• PROB30/40 - 30% or 40% probability

🛩️ Flight Rules Categories

VFR

Visual Flight Rules

• Ceiling ≥ 3000 ft
• Visibility ≥ 5 miles
• Good for visual flying

MVFR

Marginal VFR

• Ceiling 1000-3000 ft
• Visibility 3-5 miles
• Caution for VFR

IFR

Instrument Flight Rules

• Ceiling 500-1000 ft
• Visibility 1-3 miles
• Instruments required

LIFR

Low IFR

• Ceiling < 500 ft
• Visibility < 1 mile
• Challenging conditions

💡 TAF Reading Tips

For Student Pilots:

• Focus on the plain English explanations above
• Pay attention to flight rules categories
• Look for wind direction relative to runway headings
• Check for temporary conditions (TEMPO)

For Experienced Pilots:

• Cross-reference with raw TAF for precise timing
• Consider probability forecasts for alternate planning
• Monitor BECMG periods for gradual changes
• Always check current METAR vs TAF forecast

Important: TAF forecasts should always be supplemented with current METAR observations, PIREPs, and other weather information for complete situational awareness. Weather can change rapidly, and forecasts have inherent limitations.
