What is correct about conversion of fuel volume to mass?
  • A
    It may be done by using standard fuel density values as specified in the Operations Manual, if the actual fuel density is not known.
  • B
    It must be done using fuel density values of 0.79 for JP 1 and 0.76 for JP 4 as specified in JAR - OPS, IEM - OPS 1.605E.
  • C
    It may be done by using standard fuel density values as specified in JAR - OPS 1.
  • D
    It must be done by using actual measured fuel density values.

FUEL DENSITY

(a) If the actual fuel density is not known, the operator may use standard fuel density values for determining the mass of the fuel load. Such standard values should be based on current fuel density measurements for the airports or areas concerned.
(b) Typical fuel density values are:

(1) Gasoline (piston engine fuel) – 0.71
(2) JET A1 (Jet fuel JP 1) – 0.79
(3) JET B (Jet fuel JP 4) – 0.76
(4) Oil – 0.88
