18 Questions
What must be sensed for the control box to open the firewall valves in an emergency mode?
Low engine torque
In the emergency mode, what enables fluid injection to the remaining operating engine?
Engine's torque switch
What action stops the flow of fluid to the engine in an emergency mode?
Selecting OFF function
What needs to happen for fluid to be delivered to both engines in the CONT position?
High engine torque
What would cause the firewall valve to close and stop fluid flow to the engine in the CONT position?
High engine torque
What condition must be met for the system to be electrically powered in both emergency and CONT positions?
Power levers forward of flight idle gate
What is one of the components of an AB system that helps ensure pressure in the AB duct does not affect normal engine operation?
Afterburner fuel control
When does the AB fuel pump and AB fuel control operate in an aircraft?
Only when AB is selected
Which method is NOT used for AB ignition systems?
Mechanical ignition
What component in an AB system helps ignite the afterburner using sparks?
Ignition system
What is the primary purpose of the engine-driven fuel pump in an AB system?
To supply fuel to the AB fuel control unit
Which component in an AB system is responsible for controlling the flow of fuel when pilot selects AB?
Afterburner fuel control
What is the purpose of the engine torque pressure switch mentioned in the text?
To sense engine torque pressure
What is the function of the metering valve in the system described?
To ensure the correct amount of fluid is delivered to the engine
What action leads to fluid pressure building to 30 PSI as mentioned in the text?
Moving the power levers past flight idle
What happens when the selector switch is in the OFF position?
Electrical power to the pump and arming circuits is removed
How does advancing the power levers past flight idle affect fluid flow into the engine's spray manifold?
The firewall valve at each engine remains closed
In what scenario would an engine developing less than 600 foot-pounds of torque have flow stopped to it?
When the power lever is retarded or if the engine fails
