C
The FQPU has two channels, 1 and 2, that operate: (B1, B2)
a. independently
b. as backup to each other
c. in parallel processing signals from the same tank units.
A
To manually measure fuel quantity with the fuel measuring stick assemblies, you can get airplane attitude (pitch and roll) information: (A, B1, B2)
a. by using inclinometers (in the nose wheel well) and the leveling scale (in the right main wheelwell) only
b. by using the pitch and roll data from the fuel quantity maintenance page 2 only
c. by using inclinometers (in the nose wheel well) and the leveling scale (in the right main wheel well) or the pitch and roll data from the fuel quantity maintenance page 2
