Final answer:
The rudder boost low pressure light indicates that supply line pressure to the rudder power unit is below a model-specific threshold. It is armed with engine start and monitors the system during flight.
Step-by-step explanation:
The rudder boost low pressure light indicates that the pressure in the supply line to the rudder power unit is below a certain threshold, which is often specified by the aircraft manufacturer and can vary depending on the aircraft model. The light is typically armed with the engine start and remains active as a monitoring system during flight operations. In general, when this light illuminates, it serves as a warning to the pilot that there is not enough hydraulic pressure being supplied to the rudder power unit, which could affect the aircraft's yaw control and overall maneuverability. Maintenance or further inspection of the hydraulic system may be required to ensure proper function of the rudder controls.
The rudder boost low pressure light indicates that the pressure in the supply line to the rudder power unit is below a certain threshold. The light is armed with two things: a low pressure sensor and an indicator circuit.
