The in-flight thrust detent for limit is determined by which thrust lever position?

• A. The most advanced thrust lever position
• B. The center detent
• C. The least advanced detent
• D. Idle detent

Answer: (C)

In-flight, the thrust limit detent is defined by the least advanced thrust lever position among the two engines. The autothrust/thrust limiter sets the maximum allowed thrust to a value that cannot exceed what the slower engine can deliver, ensuring both engines stay in a safe, balanced range and preventing excessive asymmetry. If one lever is at a high setting (toward TOGA) while the other is kept back (toward idle or a more retarded position), the limit remains tied to the least advanced position, so you won’t command more thrust than the slower engine can reasonably provide. This is why the least advanced detent determines the limit. Choosing the most advanced detent would let one engine be commanded well ahead of the other, which isn’t desirable for control and safety. The center or idle detents aren’t the reference used to set the in-flight thrust limit.
