While on the visual portion of the ILS 33 to GRK we received multiple 'glide slope' call outs from EGPWS below 100-150 ft. AGL. Through the entire approach the aircraft appeared to be perfectly stable. We crossed the Runway threshold at about 40 feet and made a normal landing within the touchdown zone. I believe we continuously remained in a position to make a normal landing using PAPI and other outside cues. When the 'glide slope' warning sounded the First Officer automatically pulled the nose up a little; and made a 'correcting' call out. Due to that action we touched down passed the 1000 foot markers but well within the touchdown zone. We exited the runway at taxiway C with minimal braking.Suggestions: It's been at least a couple of years since I've been to GRK; but I remember having a similar experience with the glideslope for Runway 33 in the past; below published Decision Altitude. There's also a note on the approach plate stating that VGSI is not coincidental with ILS GS.
The crew was shooting the ILS 33 into Killeen. We were visual at 500ft. The autopilot was disconnected at 200ft (minimums) and in poor weather conditions we anticipated not overshooting the touchdown zone. In result; we received multiple glide slope annunciation from the aircraft. The aircraft was stable through the entire approach and corrective actions were taken having the crew cross the threshold at 40 feet.The cause for event was not allowing myself to transition to visual conditions with adequate time. I had continued to fly visually with little regard to instruments leading to an illusion. Corrective action was taken with a stable aircraft landing safely in the touchdown zone.Suggestions: Rely on automation longer to allow eyes to adjust to visual conditions reducing chance of illusions.
Air carrier flight crew reported receiving multiple 'glideslope' warnings while in a stable ILS approach to GRK.
