functions are listed in Section 1.2.6
1.2.3.2 The SAC 7-35 is for navigation information only and not for primary flight information.
1.2.3.3 Fuel flow limited to 2000 input pulses per second.
The SAC 7-35 fuel flow conversion is limited to 2000 input pulses per second
For example, do not install where the K factor and maximum fuel flow exceed:
500K — 14,400 gph
19700K — 365 gph
84600K — 85 gph 130000K — 55 gph
