Corporate flight crew reports egpws terrain warning during visual approach to mso. The flying first ...

Narrative:

We were descending to the cleared altitude of 8;500 ft MSL and spokane approach gave us the clearance for the visual approach and we had the missoula airport and all surrounding terrain in sight. I adjusted the heading to a right base leg towards the 5 mile intercept for the runway 29 final approach course and was descending on a stabilized descent at approximately 1;500 FPM to intercept the vpath. While slowing from 200 KIAS to 170 KIAS and configured at flaps 20; we had an initial egpws terrain warning and shallowed the descent rate. The terrain alert display showed an area in red to the left of the aircraft and a subsequent egpws warning as received. I disconnected the autopilot and executed a GPWS pull-up maneuver for a very brief time and then returned to the vpath for the rest of the visual approach to landing. I was visual at the time of the egpws alerts and verified the flight path was clear of all terrain and could be continued. The pilot not flying called for the pull-up and I complied. Monitor the look ahead egpws display closely and avoid penetrating the higher amber area. Discuss as a crew if there is a GPWS pull-up alert how you will react in visual conditions.

Title: Corporate flight crew reports EGPWS terrain warning during visual approach to MSO. The flying First Officer elects to ignore it initially but the Captain suggests a pull up. Approach continues to a visual landing.

Narrative: We were descending to the cleared altitude of 8;500 FT MSL and Spokane Approach gave us the clearance for the visual approach and we had the Missoula airport and all surrounding terrain in sight. I adjusted the heading to a right base leg towards the 5 mile intercept for the Runway 29 final approach course and was descending on a stabilized descent at approximately 1;500 FPM to intercept the VPATH. While slowing from 200 KIAS to 170 KIAS and configured at flaps 20; we had an initial EGPWS terrain warning and shallowed the descent rate. The terrain alert display showed an area in red to the left of the aircraft and a subsequent EGPWS warning as received.
