A deadheading crewmember reported that a B757 landing at EDDP received a EGPWS 'TOO LOW TERRAIN' warning on short final to Runway 8R. The aircraft was VMC and continued to land with no obstacles in sight. The EGPWS database may be inaccurate because of a runway configuration change.

Narrative

I have a general Safety concern. I was a deadhead crewmember positioning from EDDP. No company policies or FAA regulations were circumvented. The crew mentioned that they got a GPWS 'TOO LOW TERRAIN' on approach. Per the QRH they completed the approach and landing. The note says that in DAY VMC; with positive visual verification; the approach may be continued. My general safety concern is why did this happen? We do not want GPWS cautions or warnings to go off for no reason. It's a huge distraction on short final. In my opinion; the aircraft and/or GPWS database needs to be updated. At EDDP; Runway 8R/26L opened 5/7/2007. It was an old runway and they reconstructed it to parallel the north runway. When they reconstructed the south runway; they turned it 20 degrees to parallel the north runway. I think the GPWS sensed the old runway or no runway at all and issued the caution. I think somebody needs to update the aircraft and/or GPWS database for EDDP; Runway 8R/26L. It is a new/reconstructed runway. Our operations specifications only showed 8/26 as runways until recently.
