This test causes the probe heat monitor system to be tested. The PROBE HEAT caution light on the caution panel will blink.

EPU/GEN

This test causes the EPU to engage for the supply of electrical and hydraulic pressure.

This test also causes the flight control surfaces power to be tested. This will illuminate the FLCS PWR lights for both channels on the left and righthand side.

FLCS TEST
