Narrative:

We were cleared for the RNAV visual approach 26R. On the final segment; I selected the ILS frequency to get the blue overlay as a back up. As we began the descent at the FAF using snowflake guidance; I became uncomfortable with the descent rate and recall 'feeling low.' I disconnected the autopilot; corrected the pitch and called for flaps 45 degrees. It wasn't until after the flaps were set at 45 degrees when I noticed that we were just below 1;000 ft above airport elevation. This was the first RNAV visual approach I have flown; so I was focusing most of my attention to altitude restrictions and verifying that the aircraft was following the correct approach path. I was briefly confused that the blue overlay didn't appear (because the ILS was not loaded.) the snow flake descent took us below the standard glide path; so I had to disconnect the autopilot and reestablish glide path.

Original NASA ASRS Text

Title: A CRJ-200 Captain; flying his first ever RNAV Visual approach to Runway 26R at ATL; tuned; but did not display; the ILS as a back up to the RNAV driven 'snowflake.' Confusion reigned until he was 'feeling low' on the approach and reverted to visual perception to arrest his excessive rate of descent; restabilize and complete the approach and landing.
