Narrative:
While enroute to cak; the aircraft was descending through 4;500 MSL to 3;000 MSL while cleared direct to the cable outer marker. The aircraft had been cleared for a visual approach to a runway 1 and was in communication with cak tower. At approximately 4;000 MSL and six miles from cable the pm (pilot monitoring) advised his concern that the aircraft's altitude and current configuration were such that it was unlikely to arrive at cable configured to execute a stabilized approach. Simultaneously; cak tower contacted the aircraft to determine if it would like vectors to continue its descent and extend its final approach course. The pm accepted this offer and cak tower subsequently assigned a right turn to 140. A second vector to 190 was then assigned. During the turn to 190 an egpws (enhanced ground proximity warning system) 'caution terrain' warning was activated. The PF (pilot flying) disengaged autopilot and executed a climb of approximately 400 feet and the alert cased ceased. The pm notified the tower of the alert and the altitude adjustment that was made in response to it. The approach and landing was then completed. It is unclear as to why the alert occurred as the aircraft was on vectors and was well above cak tower's minimum vectoring altitude. The timing of this event (10.4 hours into the duty day / leg 3 / at night) serves to emphasize the importance of being aware of the potential for situational awareness to degrade near the end of long duty days. Pilots should always review of any notes contained in the station bulletin that relate to the approach during the approach brief.
