14.5.1.6.1. Subtract climb fuel from the TOGW to obtain the start cruise gross<br />
weight.<br />
14.5.1.6.2. Subtract TTC from the total time to obtain cruise time.<br />
14.5.1.6.3. Enter the appropriate TO 1C-130xx-1-1 Part 5 figure to extract fuel flow.<br />
Entering arguments are start cruise gross weight, pressure altitude and temperature<br />
deviation. Fuel flow extracted is per engine. Multiply the extracted fuel flow by four<br />
to arrive at fuel flow total.<br />
14.5.1.6.4. Divide the fuel flow total by 60 and multiply by the cruise time to obtain<br />
start cruise fuel.<br />
14.5.1.7. End Cruise.<br />
14.5.1.7.1. Subtract start cruise fuel from the start cruise gross weight to obtain end<br />
cruise gross weight.<br />
14.5.1.7.2. Enter the appropriate TO 1C-130xx-1-1 Part 5 figure to extract fuel flow.<br />
Entering arguments are end cruise gross weight, pressure altitude and temperature<br />
deviation. Fuel flow extracted is per engine. Multiply the extracted fuel flow by four<br />
to arrive at fuel flow total. This is also the terminal fuel flow (TFF).<br />
14.5.1.8. Average Cruise Fuel Flow.<br />
14.5.1.8.1. Average the start cruise and end cruise fuel flow to obtain the average<br />
cruise fuel flow.<br />
14.5.1.8.2. Divide the fuel flow total by 60 and multiply by the cruise time to obtain<br />
cruise zone fuel total.<br />
14.5.1.9. Total enroute fuel. Add the FTC to the cruise zone fuel total to determine total<br />
enroute fuel.<br />
14.5.1.10. Compute preflight endurance using the Average Cruise Fuel Flow. When<br />
computing preflight endurance, always subtract 1,300 pounds from actual ramp fuel to<br />
account for start, taxi and takeoff.<br />
14.5.1.<strong>11</strong>. For an explanation of how to compute maximum endurance fuel flow (MEFF)<br />
using the applicable TO 1C-130xx-1-1 reference the ―Maximum Endurance Fuel Flow<br />
How To Guide‖ at https://private.amc.af.mil/a3/a3v/publications.aspx under ―C-130<br />
Publications‖<br />
14.5.2. CFPS Fuel Planning<br />
14.5.2.1. For instructions on how to fuel plan using CFPS reference the ―CFPS Planning<br />
Guide‖ at https://private.amc.af.mil/a3/a3v/publications.aspx under ―C-130<br />
Publications.‖ Also, a modified electronic version of the AF Form 4<strong>11</strong>6 (CFPS 4<strong>11</strong>6)<br />
can be downloaded from the same website for use with CFPS fuel planning.<br />
14.5.3. ACFP Fuel Planning. ACFP flight/fuel plans are available to aircrew flying 618<br />
AOC (TACC) flight managed missions.<br />
14.5.4. Multi-Leg Fuel Planning. See Figures 14.1 and 14.2.
