(b) The engine TORQUE indicators (fig. 87) receive operating and lamp supply voltages from the SDC.
Engine 1 and 2 torque sensors supply torque data to the indicators.
(c) The pilot ENGOIL indicator (fig. 88) receives operating and lamp supply voltages from the SDC.
Engine 1 and 2 oil pressure sensors supply oil pressure data.
(d) The ENGRTR RPM% indicators (fig. 89) receive operating and lamp supply voltages from the
SDC. Engine 1 and 2 rpm sensors supply engine rpm (NP) data. The main rotor rpm sensor supplies rotor rpm
(NR) data.
(e) The pilot NG RPM% indicator (fig. 810) receives operating and lamp supply voltages from the SDC.
