6. Defective Fuel Level Sensor - A fuel sensor can become intermittent or change resistance with

age. It is not uncommon to find intermittent problems even in new sensors. We recommend
Stewart Warner F-385-CP05 resistive sensors be used with the FL-1RA. An intermittent problem
with a fuel sensor will most likely show up as wandering or inaccurate readings on the FL-1. Al-

alternate plans for bad weather. Keep this information available in the aircraft during the flight.
Keep a chart of the published fuel flows for various flight/engine conditions in the aircraft. Keep a
chart of the measured fuel flows for various flights in the aircraft. Measured fuel flows can be
considerably different from published figures. This is usually due to old inaccurate engine instru-
ments.
