Narrative:
At night; cleared for the visual to runway 3 in cho we were heading southwest to establish ourselves on the final approach course. Descending from 4;000 to 2;600 we received a GPWS warning; terrain pull up; which was immediately acted upon. Identification [through] GPWS aural warning. Cause [was having a] descent rate [of] 1;000 FPM; while crossing over a ridge in the area.responding upon the initial GPWS warning; I immediately disconnected the autopilot; added power and climbed; which stopped the warning right away. Suggestions [are] during the brief for the approach we discussed the terrain and that it would be on the opposite side of the approach course that we would be using. With the ipad in 'light' and not 'dark' mode there is no terrain noted on the side of the approach that we used. I double checked this. The approach plan was to be turning onto final between wuldu and sipme. Delaying the turn to outside of wuldu may have adverted this. However; at night; especially in areas with some terrain; vectors to the final approach course would be a safe action to avoid this in the future.
