Takeoff Configuration Warning Test
The takeoff configuration warning test verifies the operation of the takeoff configuration warning function. This test simulates takeoff thrust and looks for proper takeoff configuration warning function response.
When you do a takeoff configuration warning test, you also do a stabilizer green band test. You will see the green band lamps on the stabilizer trim indicators come on.
Training Information Point
The takeoff configuration warning test will supply a takeoff configuration warning only if the airplane is not in the proper configuration for takeoff.
WES System Test
The WES system test verifies the status of each one of the WES channels. The test also verifies the operation of these:
*
Master warning lights

*
Aural warning speakers

*
Stick shaker actuators.
