30.4.32.5 RPM 2
A second RPM input is provided (RPM 2 input on the GEA 24, CAP FUEL 1 / RPM 2 on the GSU 73).
For piston engines, a second RPM input from an electronic ignition system can be configured. If both RPM
inputs are configured, the highest of the two valid RPM values will be displayed. This configuration is
useful for aircraft equipped with dual electronic ignitions, where the tach signal ceases to function during a
pre-takeoff ignition check.
For turbine engines, select one of the "Custom" configurations to display a second RPM gauge. Refer to
pin description in Section 25 for supported digital signal characteristics.
NOTE
.The Sandia ST26 tach converter is required to support turbine engine RPM.
