... and their immediate surroundings. The air traffic in these areas is almost near the capacity limit. Such huge air traffic density significantly influences the decrease in the level of safety and has a negative impact on the ambient environment by cumulating of noise emission and harmful substances. Nowadays...

...Duan Junyi; Kang Xiaoming; Zhao Wansheng Purpose Field emission electric propulsion (FEEP) thruster is a type of electric propulsion based on space‐proven indium liquid metal ion sources. The lifetime of FEEP thruster limits its application in space. A better method to improve its lifetime...

... is to provide less‐fuel consumption, less noise and less emission with using CDA procedures instead of conventional procedures. Design/methodology/approach Conventional and CDA procedures were modelled in the Istanbul terminal area (TMA), which has five entry points. The real speed and the real altitude...
