The principles of an accidental spin are much the same. A spin has three basic phases. The initial phase is called an incipient spin, in which the dropping aircraft starts to enter the spin. This phase lasts only a few seconds in light aircraft. If uncorrected, an incipient spin degrades...

A: That is the thrust reduction altitude, it sounds a bit as the engines would sigh. During the takeoff, we have quite a high thrust setting, high enough that even if an engine fails, we would still get safely and easily airborne – and the excess thrust is then reduced soon af...
摘要: In addressing the overheating problem found in the JT8D-217A/C aircraft engine, China Northern Airlines has worked out a take-off EGT margin monitoring plan intended to prevent this kind of engine from overheating. The results show that the plan is effective and satisfactory....
It’s another cost item in the shopping basket, being offered by a big business which may be perceived as part of the problem in the first place. The more an airline flies, the more carbon emissions it generates. How full on average an airlines’ aircraft is can provide an indication of...

At cruise, the power requirement is dominated by parasitic power. Since this goes as the speed cubed an increase in engine size gives one a faster rate of climb but does little to improve the cruise speed of the plane. Since we now know how the power requirements vary with speed, we can...
Behind closed doors at the UK headquarters of Rolls Royce Aerospace, machinery whirs, fans hum and blades screech as some 1,000 people go about the complex task of getting an airplane engine off the ground.
