AR 95-1 Flashcards
Flight Weather Planning
- Pilots will obtain departure, en route, destination, and alternate (if used) weather information before takeoff
- Flight into icing conditions. Aircraft will not be flown into known or forecasted severe icing conditions.
- Flight into turbulence. Aircraft will not be intentionally flown into known or forecasted extreme turbulence or into known severe turbulence.
- Aircraft will not be intentionally flown into thunderstorms.
Destination Weather (IFR)
- Forecast to be equal to or greater than the published weather planning minimum for the approach procedure to be flown at ETA through one hour after ETA.
- Aviators flying helicopters may reduce destination and alternate Category A visibility minimums by 50 percent, but not less than 1/4 mile or metric equivalent (not to be used for Copter only).
Fuel Requirements - IFR
At takeoff, aircraft must have enough fuel to reach the destination and alternate airport (if required) and have a planned fuel reserve of:
30 minutes at cruise (IFR - Rotory Wing).
Alternate Airfield reguired when -
at Destination:
- Radar is required to execute the approach procedure.
- Instrument approach navigational aids to be used are unmonitored.
-
Predominant weather at the destination is forecast at ETA through one hour after ETA to be less than:
- Ceiling 400 feet above the weather planning minimum required for the approach to be flown.
- Visibility one mile (or metric equivalent) greater than the planning minimum required for the approach to be flown.
- An alternate is not required if descent from en route minimum altitude for IFR operation, approach, and landing can be made in VFR conditions.
Alternate Airfield Requirements - Weather
- Weather condition for that airfield is forecast for ETA through one hour after ETA to be equal to or greater than;
- Ceiling 400 feet above the weather planning minimum required for the approach to be flown and
- Visibility one mile (or metric equivalent) greater than the weather planning minimum required for the approach to be flown.
Alternate Airfield - Not to be used if:
- If the approach procedure to be used at the alternate is shown not authorized in FLIP.
- If radar is required for the approach procedure to be used at the alternate.
- If the instrument approach navigational aids to be used are unmonitored.
- If a Class B, C, D, or E surface area airspace does not exist or is not in effect at the airport to be used.
- If the GPS is required for the approach.
Planning
1-3-6 RULE
Can I Go (1):
1. Min Wx vs. Approach mins. (“500-1/2”)
Do I need an Alternate (3):
- *1. M - Monitored
2. W - Wx - Planing min. + 400-1 @ ETA +1 Hr
3. R - Radar Required**
Alternate Requirements (6):
1. W - Wx - Planing min. + 400-1 @ ETA +1 Hr
Worst of; Forscast, Tempo, Becoming
2. G - GPS - NoGo.
3. R - Radar Req. - NoGo
4. A - A NA - NoGo
5. M - Monitored
6. S - Surface Based Airspace (B, C, D orE)
———————– OR ———————–
VFR Exception Rule;
If you can descend VFR from minimum IFR altitude and do the descend and landing VFR, you can skip all of the above.
Prior to IFR GPS flights
- Pilot will ensure/ check:
- GPS NOTAMs and/or receiver autonomous integrity monitoring.
- Required navigation performance levels can be met when operating in designated required navigation performance airspace.
- IFR GPS flight will not be conducted with an expired navigational database.
- The appropriate suffix for GPS and/or area navigation equipment will be entered on the flight plan
Departure procedures
- All aviators will comply with published nonstandard IFR takeoff minimums and departure procedures in flight information publications.
- Aviator flying the A/C on T/O who has logged 50 hours or more of actual weather time as PIC has no Army takeoff minimums (not sim hrs).
- *Less than 50 hrs Heli:**
- *Ceiling 100 feet** and either visibility 1/4 mile, RVR 1,200 feet, or metric equivalent.
- The RVR may be used when takeoff is made from the runway for which RVR is reported.
SVFR
- SVFR flights within and departures from Class B, C, D, and E airspace are authorized provided the weather requirements are met and an appropriate ATC clearance is obtained.
- Army helicopter SVFR minima is one-half mile visibility and clear of clouds unless higher minimum is required at the airfield.
IFR GPS departure procedures are as follows:
- The area navigation and/or GPS DP must have terminal receiver autonomous integrity monitoring availability prior to departure.
- The Course Deviation Indicator (CDI) sensitivity will be set to + or - 1nm sensitivity or as published. Cross check of published paper DPs to the database retrieved procedure is required.
- The FAA National Aeronautical Charting Office “copter only” departure procedures will be flown at 70KTS or as published.
En route procedures
- During IMC flight, all instruments and communication equipment in the cockpit will be kept in the “on” position and immediately available for use.
- Reports and radio phraseology will conform to DOD and/or U.S. Government FLIP.
- An aviator may request ATC clearance to hold at any time if fuel and alternate requirements can be met.
- Holding will be in accordance with DOD/U.S. Government FLIP and or approved commercial and/or non-U.S. Government approved procedures.
