A

Should any conflict arise, AGC/APC charts may be more updated than AMM so they shall take precedence, and chart NOTAMS take higher precedence over all chart published informtaion.

30
Q

Define the RCF Procedure

UAE OM-C 10.1.7.6.1

A

A flight planned using Reduced Contingency Fuel Procedure via a decision point along the route. The ability to plan a flight with a lesser amount of fuel than the normal 5% (3%)-CONT provided a suitable Enroute Alternate (ERA) is nominated. The procedure may be required if the aircraft cannot carry the normal fuel load due to tank capacity limitation or for payload optimisation.

31
Q

Decipher this RCF Procedure

UAE OM-C 10.1.7.1.4

A
  • Enroute Alternate WMKK
  • Decision Point IGOGU followed by route to ERA
  • TRI-WMKK is Trip fuel from DEP to ERA = 55863
  • Contingency for this RCF segment is 5 percent of the Trip to ERA = 2793
  • TOT is Above TRIP+CONT+FRSV
  • MIN DP FUEL is self explanatory
