1. Angle of Attack - The CGR must be calibrated with the aircraft in a cruise angle of attack.
If the aircraft is in an angle of attack other than cruise, the CGR may display inaccurate fuel
levels (depending on the mounting location and type of sensor used). If your aircraft does not sit
at a cruise angle of attack when on the ground, it may not display accurate fuel levels. Test your

Full Fuel Readings - As a tank is filled the fuel sensor may not be able to detect the fuel
entering the upper corners of the fuel tank. If this is the case with your sensor, the CGR will
display lower fuel levels 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
