DATA
KDI 1903TCR-MP
Power ratings refer to engines equipped with air filter, standard muffler, after running-in period at ambient conditions of +25°C, relative humidity 30% and 1 bar. Power levels drop by 1% every 100 m altitude and by 2% every 5°C above +25°C.
NB – Power curve - ISO 3046/1-IFN
P – Propeller demand curve
MB – Torque curve (NB curve)
