Narrative:

We were intercepting the GS prior to the localizer and also configuring. The captain was looking for the runway so he could descend. At this point the plane started to climb. At first I didn't notice because I interpreted the movement as the GS coming down, not as going up. At 150 ft, I called out we were high and the captain arrested the climb 300 ft high then intercepted the GS and continued down on the localizer. Supplemental information from acn 308340: aircraft climbed 300 ft above intercept altitude for approximately 5 seconds, then captured GS.

Original NASA ASRS Text

Title: A300 FLC BALLOONED ABOVE GS DURING VISUAL SCAN AND CONFIGURING FOR THE APCH.

Narrative: WE WERE INTERCEPTING THE GS PRIOR TO THE LOC AND ALSO CONFIGURING. THE CAPT WAS LOOKING FOR THE RWY SO HE COULD DSND. AT THIS POINT THE PLANE STARTED TO CLB. AT FIRST I DIDN'T NOTICE BECAUSE I INTERPRETED THE MOVEMENT AS THE GS COMING DOWN, NOT AS GOING UP. AT 150 FT, I CALLED OUT WE WERE HIGH AND THE CAPT ARRESTED THE CLB 300 FT HIGH THEN INTERCEPTED THE GS AND CONTINUED DOWN ON THE LOC. SUPPLEMENTAL INFO FROM ACN 308340: ACFT CLBED 300 FT ABOVE INTERCEPT ALT FOR APPROX 5 SECONDS, THEN CAPTURED GS.
