Synopsis
Air carrier flight crew reported over shooting the final approach course on a visual approach resulting in receiving a 'caution obstacle' alert. The crew attributed the event to a miscalculation regarding the strength of the crosswind.
Narrative
We briefed the Approach [for] Runway XX before our descent. All fixes and crossing altitudes for the approach where entered into the FMS. After being cleared for the approach we crossed ZZZZZ waypoint at 1500ft and fully configured. The current descent rate to ZZZZZ1 was not enough to cross at the required altitude. PF then increased the descent rate and then disconnected the autopilot. Then before reached ZZZZZ1 Tower asked for us to 'square our turn to final.' The PF (Pilot Flying) crossed at the required altitude but with strong crosswind the A/C slightly crossed the inbound course to ZZZZZ2. We received one 'caution obstacle' aural that was corrected by the course reversal back to the right. The descent rate for the crossing at ZZZZZ1 had to be increased. The rate selected was more than intended. Then PF disconnected the autopilot to correct the descent and now hand flying the turn at ZZZZZ1 was not adjusted for the crosswind. Captain's Analysis:Descent management and situation awareness is a must. The Approach [for] Runway XX should have flown with autopilot because of the high work load and 90 degree turn at ZZZZZ1.
Second reporter narrative
Performing the Approach for Runway XX; on descent after the ZZZZZ waypoint PF (Pilot Flying) did not descend quickly enough for the next waypoint. Descent rate was increased and plane nosed down more abruptly than intended. At this time PF disconnected autopilot and continued descent. At same time Tower had asked us to square our turn to final and wind correction for strong crosswind was misjudged. Consequently PF slightly overshot final approach course. While our altitude was maintained our course brought us slightly closer to obstacle than allowed. This resulted in a 'caution obstacle' aural message. This occurred for only a moment as we were already in transition to the extended centerline. A normal landing occurred.Inadvertent rapid descent which led PF to disconnect autopilot and slightly overshooting runway centerline due to strong crosswind.Closer attention to descent required and what is actually occurring. Awareness of strong crosswind turning base to final; especially in areas of lower altitudes with obstacles present.
