  3. ENABLING LEARNING OBJECTIVE A Determine Available weather briefing sources for flight planning purposes IAW AR 95-1, FIH, and FM 3-04.240.

  4. Sources of weather Briefings In Order of Priority • Face-to-face U.S. Military forecaster. • Operational Weather Squadron (OWS). • Telephonic (FIH). • Closed circuit television • Flight Service Station (FSS) • In Person • Telephonic (1-800-Wx Brief) • Radio Remote Communication Outlet (RCO)

  8. ENABLING LEARNING OBJECTIVE B Determine Departure, Destination, and Alternate Weather Requirements IAW AR 95-1, DoD FLIP, and AR 3-04.240.

  9. DeparturePlanning • Current conditions at time of departure. • Pilot flying the aircraft at Take-Off determinesrequirements. • More than 50 hours Wx time as PC • 0 - 0 • Less than 50 hours Wx time as PC • 100 – ¼ (Helicopter) • Non-standard requirements must be applied.

  10. Use Table of Contents to ….. • Determine if IFR Take-Off, (OBSTACLE) Departure Procedures are listed for your departure airfield. (Non-Standard Requirements)

  11. Destination Planning Weather Forecast Predominant Weather Ceiling and Visibility Requirements Forecast Valid Times Area Forecast

  12. IFR Requirements Destination Approach Procedure 1/4

  13. Alternate Airfield Required? • Radar Required • Navigational Aids Unmonitored • Predominant Weather Less Than: • Ceiling 400 Feet Above Planning Minimums • Visibility 1 Mile greater than required after reduction by 50%. • Exception - Not required if descent from enroute minimum altitude, approach, and landing can be made in VFR conditions

  14. Alternate Airfield Required? Destination Approach Procedure 1/4 400 - 1 600 - 1 1/4

  15. AlternatePlanning Weather Forecast Worst Weather Ceiling Visibility Requirements Forecast Valid Times Area Forecast

  16. Alternate Airfield Selection • Worst Weather. • Ceiling 400 Feet above required. • Visibility 1 Mile greater than required after reduction by 50%.

  17. Alternate Selection Alternate Airfield Approach Procedure 1/4 400 - 1 600 - 1 1/4

  18. A Alternate Airfield Selection WILL NOT be selected if….. • Not Authorized ( NA ) • Radar Required • Navigational Aids Unmonitored • B, C, D, or E Surface Area not in effect • GPS • Exception – May be used if descent from enroute minimum altitude, approach, and landing can be made in VFR conditions

  19. ENABLING LEARNING OBJECTIVE C Determine additional sources of weather Information after flight planning IAW AR 95-1, DoD FLIP, and FM 3-04.240.
