Final answer:
False. An in-flight 'OP GO' indication switching to a 'DEGD' indication without change in ENG STATUS when the aircraft slows below 80 KCAS after landing is not normal.
Step-by-step explanation:
An in-flight "OP GO" indication switching to a "DEGD" indication without change in ENG STATUS when the aircraft slows below 80 KCAS after landing is not normal.
The "OP GO" indication typically means that the engine is operating normally, while the "DEGD" indication signifies that there is a degraded engine condition. If the indication switches without any change in engine status, it could indicate a malfunction or anomaly in the engine system.
