L-1011 Engine: Reverser System

The reverser system if for ground use only and is used to slow the aircraft. The revers are operated by a separate set of levers forward of the thrust levers:

1. Forward thrust levers at idle 
2. Lift reverse thrust lever to reverse idle detent
3. Autothrottle clutch and cable system moved in direction for reverse thrust operation

There are a number of switches that are actuated by the reverser: The switch module actuals switches to:

1. Select flight idle RPM
2. Energize dual selector valve reverse thrust solenoid 
3. Power control mechanism actuates mechanical input to dual selector valve 
4. Translating cowl moves to deployed postion
5. Further movement of reverse thrust lever increases rpm through cables and tele flex cable

When the thrust levers are stowed the following actions happen:

1. Grund idle circuit energized
2. Dual selector valve solenoid de-energized 
3. Mechanical input returned to forward thrust selection 
4. Translating cowl moves to stowed postion 
5. Increased forward thrust is again available
