Propeller Tachometer-Generator

Another propeller-related accessory is the propeller tachometer-generator, located on the

reduction gearbox. Turning at the same speed as the propeller, this tachometer-generator

provides the electrical signal to operate the propeller RPM indicator. Located on the instrument

panel in both cockpits, the propeller RPM indicator is graduated in 50-RPM increments from 0 to

2500 RPM. The normal governed operating range of the propeller is 1800-2200 RPM with a

maximum allowable of 2200 RPM. For normal T-34C operations, the condition lever will be at

full increase and the propeller rotating at 2200 RPM.
