SECTION X. FUEL FLOW
The idle fuel flow chart (fig. 7A-10-1) presents engine fuel
flow sensitivity to PA and FAT for ground idle and flight
7A-10-2. Use of Chart..
The primary use of charts is illustrated by the example.
To determine idle fuel flow, it is necessary to know idle
condition, PA, and FAT. Enter PA, move right to FAT,
move down and read fuel flow.
Presented charts are based on the use of JP-4
Ground idle is defined at 50 to 59% N1.
Thrust ground detent is defined as engine condi-
tion levers at FLT, NR selected 97%, and thrust control at
