te Sa a konfigirasyon chwazi prensipalman pou misyon pou minimize Asymétrie nan ki fèt nan ka ta gen echèk motè, espesyalman nan yon motè ekstèn (ki se komen sou avyon militè nan yon teyat de operasyon). Men, li tou te gen enplikasyon anpil: mwens efò sou zèl a, kote ki posib estrikti sekou. Anplis de sa, gwosè a nan flote nan te redwi depi koreksyon an ekar ka gen mwens nan ka ta gen echèk motè yo, pou redui trennen. Karakteristik sa yo de pèmèt pou pi gwo kapasite seri oswa pote yon chaj pi lou pou menm kantite lajan an nan carburant50. kat motè yo se aktyèlman ki idantik, men de motè yo ekipe ak yon Kovèti pou ranvèse yon direksyon ki nan wotasyon nan propele la.

This configuration was chosen primarily to minimize the asymmetry that occurs in case of engine failure, especially of an external motor (which is common on military aircraft in a theater of operation). But it also has many implications: less effort on the wing, where possible relief structure. In addition, the size of the drift has been reduced since the yaw correction may be less in case of engine failure, reducing drag. These two features allow for greater range capability or carrying a heavier payload for the same amount of carburant50. The four engines are actually identical, but two engines are equipped with a gear reversing the direction of rotation of the propeller.
