The maximum N1 at transient is:

Explanation:
During a rapid throttle change, the engine control allows a brief N1 overshoot above the steady-state limit to deliver prompt response. This transient limit is higher than the continuous limit and is capped to protect the engine from surge or other damage. For the Beechjet 400A, that transient N1 limit is 104% rpm. Once the transient passes, N1 settles back toward the commanded value, typically around the continuous limit. Therefore, the maximum N1 observed during transient operation is 104% rpm, while 100% rpm represents the continuous ceiling and other values are not used as the designated transient cap.
