<标题> Lack of awareness of the degrading energy state of the aircraft is also an important contributor to the statistics relating to crashes linked to poor energy management. The reason for this lack of awareness is not clear and requires more research but speculations and theories as to why this phenomenon takes place include distractions, increased workload, and auto-flight monitoring and warning. For example, the 2009 Turkish Airlines crash mentioned above had occurred due to the failure of an altitude sensor which in its turn caused premature autothrottle mode changes during the approach. The accident happened due to the fact that the experienced pilots did not detect the decreasing airspeed and altitude until the very moment the stall occurred, when it was too late to act in order to amend the situation and regain control of the aircraft. Therefore, we can observe the fact that the improper human decisions and flawed thinking processes that occur during high stress and workload situations are a very important factor in the occurrence of incorrect energy management of the aircraft which then can lead to flight incidents or crashes. The energy level of the aircraft seems to be something that is either easily overlooked in times of stress or it is simply not detected, pilots detecting the incompatible energy regime of the aircraft only when it is too late to take up on any action to regain control of the aircraft. Distractions, improper monitoring, incorrect glide path angle, lack of awareness of the decreasing energy state of the aircraft or the total failure to detect it, all play a part in the end result which is poor energy management that can lead to crashes. This raises the question though, is it possible to devise a way of making the pilots constantly aware of their energy levels so that they make better judgements in cases of emergency? From the Human Factors point of view, any improvement in the cockpit layout or in the way information is presented to the pilot so that the actual mental workload that he is subject to decreases, is an effective way of improving the pilot`s performance.
