Over boosting is most likely to occur when which condition occurs?

Explanation:
Overboost happens when the intake manifold pressure exceeds the engine’s maximum safe limit. It’s most likely to occur when maximum power is required while the air density is still high, which is typical during takeoff or in the early climb. At that moment the throttle is fully open and the turbocharger is pushing as much boost as the system allows, so the manifold pressure can spike beyond safe levels if the boost control isn’t able to cap it quickly enough. In cruise, air density is lower and the engine isn’t attempting to deliver maximum power, so boost is more limited. Idle or closed throttle produces little boost, and partial throttle during cruise doesn’t demand enough boost to exceed the limit. That combination makes full throttle at takeoff or early climb the scenario most prone to overboost.
