SECTION XVI. IDLE FUEL FLOW C
7-59. DESCRIPTION.
The idle fuel flow chart (figure 7-19) shows the fuel flow
at flight idle and at flat pitch with 100% rpm.
7-60. USE OF CHART.
The primary use of the chart is illustrated by the exam-
ple. To determine the idle flow, it is necessary to know
the idle condition, pressure altitude, and free air temper-
ature. Enter at the pressure altitude, move right to FAT
in appropriate grid, then move down and read fuel flow
on the scale corresponding to the condition. Refer to the
cruise charts to obtain fuel flow for cruise power condi-
tion.
7-61. CONDITIONS.
This chart is based upon the use of JP-4 or JP-5 fuel and
100% rpm.
