AFI 11-2C-130v3 - BITS

AFI11-2C-130V3 23 APRIL 2012 101
6.42.1. Aircraft category. The C-130 is a category "C" aircraft. If approach speeds exceed
140 knots, the minimums for category "D" will be used.
6.42.2. Prior to starting an instrument approach, pilots will confirm their aircraft can comply
with the missed approach climb gradient requirements established in AFI 11-202V3.
6.42.3. Weather minimums. Before starting an instrument approach, or beginning an
enroute descent, pilots will confirm the existing weather is reported to be:
6.42.3.1. At or above required visibility for straight-in or sidestep approaches.
6.42.3.1.1. For PAR approaches, visibility will be no lower than RVR 2400 (730
meters) or 1/2 mile visibility (800 meters) with no RVR readout available.
6.42.3.2. At or above required ceiling and visibility for circling approaches.
6.42.3.2.1. For circling approaches with no published ceiling requirement, the
required ceiling shall be computed by taking the published HAA plus 100 feet
rounded up to the next one hundred foot value. (For example, if the HAA is 747 feet,
add 100 feet to get 847 feet and then round up to the next one hundred foot value
which would be 900 feet. Your ceiling for the approach must be at or above 900
feet.) When circling minimums are published, but not by category, circling approach
minimums will be as published, but in no case lower than 600 feet and 2 miles
visibility.
6.42.3.3. Increase the published visibility minimums of an instrument approach by ½ SM
or as noted in NOTAMs, on ATIS, or on the approach plate, when the runway approach
lighting system (ALS) is inoperative. (This applies only to the ALS itself, not to VASIs,
PAPIs, and other lights that are not a component of the ALS.)
6.42.3.4. Variable visibility/ceiling reports. If variable visibilities/ceilings are reported,
pilots may use the greatest value reported. If it is subsequently determined that weather
is below minimums for the approach, comply with paragraph 6.42.10. Do not attempt
further approaches until the lowest visibility/ceiling reported is at/above approach
minimums.
6.42.4. Flight Instrumentation Requirements.
6.42.4.1. If full flight instrumentation is not available and operational, aircraft are limited
to a DA/MDA based on a HATh (height above threshold) of 300 feet and RVR 4000, or
¾ mile visibility (1220 meters) with no RVR.
6.42.4.1.1. Category I ILS. Full flight instrumentation consists of: dual flight displays
(one flight director plus ADI repeat), complete differential pressure instruments,
heading/compass systems, and attitude indicators in the pilot and copilot positions.
6.42.4.1.2. Full flight instrumentation for a precision approach radar (PAR) consists
of: complete differential pressure instruments, heading/compass systems, and attitude
indicators in the pilot and copilot positions.
6.42.5. Category I ILS Procedures. Decision altitude for precision approaches will be as
published, but no lower than 200 feet HATh.
