Introduction,In civil aircraft, for example, the (fuel/direct operating) cost ratios have increased from 0.25 in the early 1970s to about 0.60 today. The cost effectiveness of aviation fuels is therefore a key factor in the future viability of aviation in general, and the airline industry in particular.作者: 淘氣 時間: 2025-3-22 07:36
