(d)
Write the value shown on the fuel quantity indicator.
(e)
Open the access door for the refuel control panel (P15).
(f)
Write the value shown on the applicable refuel quantity indicator.
(g)
Compare the values on the fuel quantity indicator (in the control cabin) and the values on the refuel quantity indicator (on the P15 panel). 1) The values must be the same with a tolerance of |50 pounds
(|20 kilograms).
