sit at a cruise angle of attack when on the ground, it may not display accurate fuel levels. Test
your aircraft at different angles of attack to determine how the MVP fuel level readings
are affected.
2. Full Fuel Readings - As a tank is filled the fuel sensor may be unable to detect the fuel
entering the upper corners of the fuel tank. If this is the case with your sensor, the MVP may
display fuel levels lower than the actual fuel in the tanks when the tanks are full. When the fuel
level drops to a point where the fuel sensor starts to detect a change, the displayed fuel level
should be accurate. Check the accuracy of your system by comparing the displayed fuel
levels on the MVP to the fuel levels listed in the flight manual at each fill up.
3. Low Fuel Readings - Do not rely on the MVP to determine the fuel level in the tank for
an indicated tank level below 1/8. You should always fly the aircraft in such a manner as to
at least maintain the FAA minimum fuel requirements in the aircraft at all times. Depending
on the mounting location and type of fuel sensor used, the MVP may not be able to
accurately measure the last few gallons of fuel in the tanks.
4. Improper Calibration - If the MVP has not been properly calibrated it will not display
accurate fuel levels in the tanks. It is important to verify the accuracy of the MVP. Always
crosscheck your measured fuel levels in the tanks with the readings on the MVP before
each flight.
5. Poor Connections - Poor connections between the wires leading from the EDC to the fuel
sensors can become intermittent with age. An intermittent connection most likely will show up
as wandering or inaccurate readings on the MVP. Always cross check your measured fuel
levels in the tanks with the readings on the MVP before each flight.
6. Defective Resistive Fuel Level Sensors - Fuel sensors can become intermittent or change
resistance with age. It is not uncommon to find intermittent problems even in new sensors.
An intermittent problem with a fuel sensor most likely will show up as wandering or
inaccurate readings on the MVP. Always cross check the measured fuel levels in the
tanks with the readings on the MVP at each fill up.
If you ever find an inaccuracy issue or any other problem with a fuel level display on
the MVP, disable the fuel level display (see the “Redlines, Limits and Color Setup” screen).
This will alert anyone flying the aircraft to the condition of this display.
