Which of the following is not a standard jet engine rating?

Explanation:
Engine ratings are the defined thrust settings that manufacturers publish for specific operating phases or limits. Take-off power and maximum continuous are standard ratings because they correspond to critical phases of flight and engine life limits, while cruise represents the power level used during long, level flight. Idle, on the other hand, is an operating condition—a low-power, low-RPM state used during start and idle operation—not a published thrust rating. That’s why Idle isn’t considered a standard jet engine rating.
