Has anyone ever tested a manual fuel gauge that act like a pipette - ie FuelHawk - to see if they are an accurate representation of fuel in a Piper Cherokee? The dihedral wings keep the fuel bladder at an angle so technically it should always read too low and maybe that increases safety to underestimate. The FuelHawk only reads down to 5 gallons so maybe the guage already takes the angle of the tank into consideration. I’m just curious if they are accurate or anyone has any thoughts.
