Final answer:
The two signals that DEC provides to the cockpit are the digital engine control signal and the fault detection signal.
Step-by-step explanation:
The two signals that DEC provides to the cockpit are the digital engine control signal and the fault detection signal.
The digital engine control (DEC) signal is responsible for managing and controlling various aspects of the aircraft's engines, such as fuel flow, ignition timing, and throttle position. It ensures the proper functioning and performance of the engines.
The fault detection signal is used to alert the cockpit of any abnormalities or malfunctions in the engine system. It helps the pilot and maintenance crew identify and address any issues that may arise during the flight.
