Calculation of flight parameters during the engine failure procedure on a Pilatus PC-9M aircraft

U radu je obrađen zrakoplov Pilatus PC-9M, osnovne karakteristike zrakoplova te je detaljnije obrađena pogonska skupina i način promjene koraka elise. Opisane su procedure otkaza kod višemotornih i jednomotornih zrakoplova, a za Pilatus je opisana manevar prinudnog slijetanja. Kako bi se zrakoplov doveo u uvjete manevra prinudnog slijetanja potrebna je dobra procjena i kalkulacija doleta, GPS mjerenja koja su odrađena daju jasne podatke o doletu s obzirom na proceduru spuštanja. Pilot koji posjeduje znanje o doletu pri otkazu motora s obzirom na proceduru koje je pokazano u ovom radu ima značajno veću vjerojatnost spašavanja zrakoplova i posade.This paper deals with Pilatus PC-9M engine failure, basic characteristics and propeller pitch change mechanism. Furthermore, procedures with one engine inoperative are explained in case of multi-engine and single-engine aircraft. In order to bring aircraft into the conditions of a forced landing maneuver pilot needs to calculate range, GPS measurements in this paper give clear data on the range with regard to the descent procedure. A pilot who has knowledge of data for range calculations shown in this paper, is significantly more likely to save the aircraft and crew in engine failure conditions
