GROUND TEST SWITCH (two-position, spring-loaded to center)

GND TEST - test the Flight Data Recorder (FDR) while the airplane is on the ground

• the RED-OFF-WHITE A/COL switch on the Exterior Lights Panel is set to OFF for the test
• this causes the FLT DATA RECORDER caution light to turn on
• the test is satisfactory when the FLT DATA RECORDER caution light goes out

ELT REMOTE SWITCH (three-position, spring-loaded away from RESET)

ON - manually activates the ELT in the event of an emergency

• the ON selection overrides the automatic inertia switch
• the monitor light located within the remote switch comes on
• also provides a means to test the ELT during a preflight test
• returning the remote switch to the AUTO position terminates ELT operation, and the monitor light goes off

AUTO - operates in the automatic mode

• the ELT transmits when the inertia switch activates, and the red ELT monitor light located in the remote switch comes on
• it is activated by longitudinal inertia forces between 5 and 7 G (gravity) acceleration

RESET - allows for reset of an inadvertent ELT activation
