What is the normal engine control mode setting when the TH-73A is in flight?

• A. EEC
• B. MEC
• C. MAN
• D. GOV

Answer: (A)

The normal engine control mode setting for the TH-73A during flight is the EEC, which stands for Electronic Engine Control. In this mode, the electronic control unit manages engine performance parameters such as fuel flow, RPM, and temperature to optimize the engine's efficiency and responsiveness. The EEC system allows for precise control, reducing pilot workload and increasing safety by automatically adjusting engine operations to maintain optimal performance under varying flight conditions.

This mode is crucial, as it leverages advanced algorithms to continually monitor and adjust engine parameters based on real-time data from various sensors. It helps ensure that the engine operates within its ideal performance envelope, which is particularly important during dynamic flight maneuvers.

In contrast, the other modes such as MEC (Manual Engine Control), MAN (Manual), and GOV (Governor) do not provide the same level of automated management and efficiency that the EEC mode does, making them less desirable during normal flight operations in the TH-73A.
