AR 95-23 Para 5-2 c.Flight Weather PlanningMCs will obtain departure airfield/airport, en route, destination airfield/airport, and alternate airfield/airport (if required) weather information before takeoff. The following weather requirements apply:(1) Flight into icing conditions. UAS will not be flown into known or forecast severe or moderate icing conditions.(2) Flight into turbulence. UAS will not be intentionally flown into known or forecast extreme turbulenceor into known severe turbulence. UAS will not be intentionally flown into forecast severe turbulence unless MACOM commanders have established clearance procedures and – (a) Weather information is based on area forecasts.(b) Flights will be made in areas where encountering severe turbulence is unlikely.(c) Flights are for essential training or essential missions only.(d) Flight approval authorities are specified.(e) Flights are terminated or depart turbulence if severe turbulence is encountered.
AR 95-23 Para 5-2 c.Flight Weather Planning(3) Flight into thunderstorms. UAS will not be intentionally flown into thunderstorms.(4) Destination weather. Destination weather must be forecast to be equal to or greater than visual flight rules (VFR) minimums at estimated time of arrival (ETA) through 1 hour after ETA. When there are intermittent weather conditions, predominant weather will apply.(5) Area forecast. If there is no weather reporting service, the UAC may use the area forecast.
AR 95-23 Para 5-2 c.Flight Weather Planning(6)Weather briefing. Local commanders will establish policies specifying when DD Form 175–1 (Flight Weather Briefing) is required to be filed (with DD Form 175 (Military Flight Plan) if and when required for UAS). Weather information for DD Form 175–1 will be obtained from a military weather facility. If a military weather facility is not available, the MC will obtain a weather forecast in accordance with DOD FLIPs. Automated or computer-based systems may be used to obtain weather information if the system is approved by USAASA (U.S. Army Aeronautical Services Agency) and the commander establishes a program to ensure UAS crewmembers are thoroughly familiar with the system in use.
Weather Planning•Weather service should be available either face-to-face or direct-line telephone to the flight planning facility.•Weather reports should be updated hourly or sooner if weather conditions occur that were not forecast.•The ultimate Responsibility for obtaining a complete weather briefing is the Mission Commander.
