The SK 60 Aircraft has been a workhorse for the Air Force’s training of future pilots since the late 1960s. The aging SK60 aircraft is going out of style, and the system has merely a few years of total running time left. A replacement for the SK 60 needs to be implemented in the coming years, and the Armes Forces Flying School has been commissioned to conduct flight tests on suitable replacement systems. This study will conduct a system analysis of two aircrafts mentioned in the Flying Schools report. The systems are mainly valued on their suitability as a replacement for the SK 60 from a training perspective. The systems are also valued based on the possibility of expanding the military utility of each system such as their ability to carry out attack operations. Based on the sample the Pilatus Aircraft PC -21 and BAE Systems Hawk MK 120 aircrafts were chosen for evaluation. The two planes are different yet comparable which makes them suitable for comparison in this study. Hawk MK 120 was deemed as the most suitable replacement for the SK 60. The MK 120 appeared as slightly more favorable than the PC-21 after valuation and appraisal, both from an educational point of view but also with regard to its ability for extended military purposes.
