| dc.description.abstract | N219 aircraft as a plane that is still in the test flight period needs to be evaluated and refined in various
fields, one of them is performance. Performance examines the achievements of flying like the maximum
range that plane can take using the available fuel capacity. To determine the effect of atmospheric
condition on the performance of flying then in this study given the variation of atmospheric temperature
that is on the condition ISA 0, ISA+10, ISA+20, and ISA+30. Cruise is the focus of the study because
this flight phase is the dominant in terms of distance, time, and fuel consumption. The method used is
specific fuel consumption method. This method is used to determine the speed that can generate the
maximum range. The purpose of this study was to investigate the effect of atmospheric temperature
changes on the maximum range of N219 aircraft in the cruising phase. The results show that maximum
range of aircraft increases with increasing temperature to the condition of ISA 0. Maximum range at
ISA 0 is 1.946,48 km and continous to increase until 2.224,36 km at ISA+30. This is due to the decrease
in air density by increasing atmospheric temperature to ISA 0, causing the increase in the specific air
range, thus increasing the maximum range of aircraft. | en_US |
