RPM Indicators covers cockpit and FADEC-interfaced instruments that measure and display rotational speed of turbine spools, propeller shafts, or rotor heads, encompassing tachometer generators, magnetic pick-up sensors, phonic wheel assemblies, and digital signal-processing electronics that convert frequency or pulse-count signals into calibrated N1, N2, or Nr readouts on analogue or AMLCD displays.
