Engine Exhaust and Reverser Systems What is the proper operating sequence when using thrust reversers to slow an aircraft after landing? a. Advance thrust levers up to takeoff position as conditions require, select thrust reverse, de-select thrust reverser, retard thrust levers to ground idle. b. Retard thrust levers to ground idle, raise thrust reverser levers as required, and retard thrust reverser levers to ground idle. c. Select thrust reverse, advance thrust reverser levers no higher than 75% N1, and retard thrust reverser levers to idle at approximately normal taxi speed.
