AR 95-1 Flashcards
Traffic pattern altitude at Army Airfields
(Manned) Traffic pattern altitudes at Army airfields for airplanes should be 1,500 feet above ground level (AGL). Helicopter traffic pattern altitudes should be at least 700 feet AGL.
Fuel requirements. At takeoff, aircraft must have enough fuel to reach the destination and alternate airport (if re-quired) and have a planned fuel reserve of
(1) Rotary wing.
(a) VFR, 20 minutes at cruise.
(b) IFR, 30 minutes at cruise.
Visual flight rules flight
Destination weather must be forecast to be equal to or greater than VFR minimums at estimated time of arrival (ETA) through one hour after ETA. When there are intermittent weather conditions, the predom-inant weather will apply. Aviators may file flight plans to a destination within Class B, C, D, and E surface area airspace when weather conditions are forecast to be equal to or greater than known special visual flight rules (SVFR) minima for that airspace at ETA through one hour after ETA. Helicopter SVFR minima is 1/2-mile visibility and clear of cloud unless a higher minimum is required at the airfield. For airspace class, forecast en route weather must permit flight with separation from clouds and flight visibility equal to or greater than minimums stated in table 5 – 1 of this regulation.
(Manned) Instrument flight rules flight
Destination weather must be 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. When there are intermittent weather conditions, the predominant weather will apply. 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. Reduction of visibility for approaches labeled “copter only” is not authorized, and this reduction is applied after all other corrections. Category II approach procedures may not be used in destination or alternate weather planning.
Alternate airfield planning
R U 400-1
An alternate airfield is required when filing IFR to a destination under any of the following conditions:
(1) Radar is required to execute the approach procedure to be flown.
(2) The instrument approach NAVAIDs to be used are unmonitored.
(3) The predominant weather at the destination is forecast at ETA through one hour after ETA to be less than—
(a) Ceiling 400 feet above the weather planning minimum required for the approach to be flown.
(b) Visibility one mile (or metric equivalent) greater than the planning minimum required for the approach to be flown.
(4) An alternate is not required if descent from en route minimum altitude for IFR operation, approach, and landing can be made in VFR conditions. (5) Pilots may plan for a GPS-based instrument approach at either the destination or alternate, but not at both locations. This restriction does not apply to RNAV systems using TSO – C145/C146 equipment.
Alternate airfield selection
WEATHER GRAMS
(1) An airfield may be selected as an alternate when the worst weather condition for that airfield is forecast for ETA through one hour after ETA to be equal to or greater than—
(a) 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, or
(b) The descent from en route minimum altitude for IFR operation, approach, and landing can be made while maintain-ing the VFR cloud clearance and visibility requirements for the airspace flown.
(2) An airfield will not be selected as an alternate except per paragraph 5–2f(1)(b)—
(a) If the approach procedure to be used at the alternate is shown not authorized in FLIP. ex. ANA
(b) If radar is required for the approach procedure to be used at the alternate.
(c) If the instrument approach NAVAIDs to be used are unmonitored.
(d) 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.
-GPS can only be used for the destination airport or alternate not both.
Weight and balance
The PC/AC will ensure
(1) The accuracy of computations on the DD Form 365 – 4 (Weight and Balance Clearance Form F-Transport/Tactical)
(2) That a completed DD Form 365 – 4 is aboard the aircraft (Manned) or on file and available to the AC (Unmanned) to verify that the weight and center of gravity will remain within allowable limits for the entire flight. Several DD Forms 365 – 4 completed for other loadings also may be used to satisfy this requirement. In this case, the actual loading being verified must be within the extremes of the loading shown on the DD Forms 365 – 4 used for verification.
