(1) Find the minimum oil level necessary to dispatch the airplane with these recommendations:
(a) Before each flight, the indicated engine oil level in the flight compartment with engine not
in operation must be 60% full or 12.00 U.S. quarts (11.40 liters) or more.
1) If the airplane has more than one flight between oil servicing, make sure there is
enough oil in the tank so the indicated level is always greater than 60% before each
flight.
2) There must be 7 quarts (6.65 liters) or more of oil remaining in the tank by the end
of the scheduled flights for possible takeoff and go around (TOGA) operation.
(b) Calculate the oil usage from the flight(s) duration and the specific engine oil consumption.
(c) The minimum oil level necessary for dispatch should include the 60% and the oil usage.
