Answer» RIGHT option is (a) True For explanation I would say: In cruise performance the fuel mass flow determines the RATE of change of mass of the AIRCRAFT. It is EXPRESSED by the formula Qf=\(\frac{-dm}{DT}\) where dm is mass rate and dt is time rate. The fuel mass is always negative as mass of the aircraft always decreases. |
