System Description:
The FP-5 and FP-5L are models of a fuel flow computer instrument packaged in a 2.5" by 2.5" by 3.65"
depth case. Each of the instruments connects to a fuel flow transducer which is mounted in the engine cowling
area. A single "AUX" (auxiliary) Channel is optional and may be used to monitor one of the following functions:
EGT (provides compensation for Horsepower when leaning), CHT, Oil Temp, OAT, Carb. Temp, Fuel Pressure,
Oil Pressure, Manifold Pressure, Gyro Vac, Bus Voltage or Amps. Each function requires a Functional Module
(3" x 2" x 1" box) that comes with the appropriate transducers and cables. More than one function may be
monitored using a remote switch.
The fuel flow transducer is mounted in the fuel line going to the carburetor (or flow divider on an injected
engine). If the rotor in the flow transducer becomes blocked, it will not reduce the flow of fuel to the engine. The
FP-5(L) instrument connects to the transducers via a wire harness. The instrument and transducers employ
connectors so they may be removed safely and quickly from the aircraft.
The FP-5 and FP-5L each have seven display modes: Fuel Flow, Horsepower, Fuel Remaining, Fuel Used
Since Fill Up, Fuel Used for the Flight, Time to Empty, and AUX Channel. The FP-5L has all the features of the
FP-5, with four additional display modes: Nautical Miles per Gal, Statute Miles per Gal, Fuel to Destination and
Fuel Reserve.
