For aircraft on which an inspection window has been installed on the Left Lateral Console Panel that permits visibility of the Flight Idle Stop Solenoid Breakers:
Using an appropriate light source, perform a visual check to verify that both “FLT IDLE STOP SOL” circuit breakers CB0582 and CB0583 for Engine 1 and Engine 2 are closed.
Note 1: This check may be performed by a flight crewmember.
Note 2: Instructions for installation of an Inspection Window can be found in Embraer Service Bulletin 120-076-0014 dated 29 July 1992.
2. For aircraft without an inspection window installed on the Left Lateral Console Panel:
Perform a visual inspection to verify that both “FLT IDLE STOP SOL” circuit breakers CB0582 and CB0583 for Engine 1 and Engine 2 are closed.
3. Conduct a functional test of the Secondary Flight Idle Stop System (SFISS) for Engine 1 and Engine 2 by performing the following:
(a) Move both power levers to the “MAX” position.
(b) Turn the aircraft power switch “ON”.
(c) Open both “AIR/GROUND SYSTEM” circuit breakers CB0283 and CB0286 to simulate in flight conditions with weight-off-wheels. Wait for at least 15 seconds, then move both power levers back toward the propeller reverse position with flight idle gate triggers raised. Verify that the power lever for each engine cannot be moved below the flight idle position, even though the flight idle gate trigger on each power lever is raised.
(d) Move both power levers to the “MAX” position.
