DA 40 AFM
(h) High Fuel Flow
Fuel flow in the red sector:
1. Electrical fuel pump . . . . . . . . . . . . . . . . . . . ON
2. Fuel pressure . . . . . . . . . . . . . . . . . . . . . . . check after 10 - 15 sec:
* If the fuel pressure is low, refer to 3.2.3 (i) - LOW FUEL PRESSURE WITH
THE ELECTRICAL FUEL PUMP SET TO ON.
* If the fuel pressure is in the green sector, or the fuel pressure warning light
is not illuminated, the likely cause is a defective fuel flow indication, which
should thus be ignored (the airplane should be serviced). Fuel flow data
should be taken from the engine performance table in Chapter 5.
3. Check fuel quantity. A rapid reduction in fuel quantity confirms a high fuel
flow.
