5.18.4.3. For other than hard-surfaced runways or taxiways, the airfield must be listed in
the ASRR as certified or have a current LZ survey.
5.18.5. RCR Limitations. When RCR is not available, the PIC will refer to the flight manual
for standard ICAO conversions based on general runway condition; be conservative when
dealing with unknown conditions (e.g., forward operating bases (FOBs), unpaved runways).
Normally, RCR values are not reported for taxiways and ramps. During periods of reported
low RCR, the taxiways and ramps may have an even lower RCR than reported for the
runway. The runway surface should be considered wet when water on the runway causes a
reflective glare.
5.18.5.1. RCR and RSC. The performance charts used to determine braking action are
based on concrete runways. The RCR values for the following runway surfaces in Table
5.5 are estimates based on operational experience and should be used only as a guide.
Table 5.5. RCR Values.
TYPE SURFACE RCR (DRY) RCR (WET)
Asphalt 23 12
Aluminum Matting 20 10
M8A1/With Anti-Skid (PSP) 20 8
Clay 16 5
Crushed Rock 16 5
Sand 16 5
M8A1/Without Anti-Skid (PSP) 13 3
5.18.5.2. Limit C-130 operations into and out of slush or water covered runways to a
covering of one inch. This number is based on performance charts where an RSC of 10 is
equal to one inch of slush or water. Performance data where more than one inch of slush
or water is present may not be accurate.
5.18.6. Wind Limitations. All maximum effort operations must fall in the "recommended"
area of charts (corrected for RCR) unless otherwise approved by OG/CC.
5.18.7. Takeoff Speeds. If Vmeto is used for takeoff, climb until clear of the real or
simulated obstacle at max effort obstacle clearance speed. If Vmca is used for takeoff, climb
until clear of the real or simulated obstacle at Vmca + 10 knots.
5.18.7.1. If obstacles are a factor, use Vmeto and max effort obstacle clearance speed
without Vmca corrections. If unable to clear obstacles using Vmeto and maximum effort
obstacle clearance speed, reduce aircraft gross weight or delay mission for more
favorable conditions.
5.18.7.2. The PIC will ultimately make the decision to use Vmeto or Vmca based on a
consideration of all available data including: weather, runway length, Vmeto, Vr, Vmca,
Vmcg, applicable airfield survey, and a review of hazards, obstructions, and terrain both
laterally and along the climb out flight path. Peacetime restrictions: take-off at Vmca or
