Narrative:

Upon arrival into orl, we were assigned an approach. The PF briefed that approach. Further in on the arrival, we were reassigned ILS runway 18R. I accepted control of the aircraft from the first officer while he reviewed the approach and retuned radios. On a vector to the 'visual' to runway 18R, we were given a heading to intercept the localizer and cross tuffe at 2300 ft MSL. On intercept heading, the first officer finished approach review and began flying the approach. After I handed the aircraft back to the first officer, I scanned the flight engineer's panel and then my instruments. We intercepted the localizer between hammi and tuffy. I noted the altitude below the assigned altitude and the GS nearly centered. I advised first officer not to descend and to return to 2300 ft until tuffy. In his correction from approximately 200 ft lower than assigned altitude, he climbed to approximately 200 ft higher than the 2300 ft crossing altitude for tuffy. This high deviation happened simultaneously with crossing tuffy. With my assistance, the approach was stabilized and we landed normally.

Original NASA ASRS Text

Title: B727 CREW HAD ALT EXCURSION IN MCO CLASS B AIRSPACE.

Narrative: UPON ARR INTO ORL, WE WERE ASSIGNED AN APCH. THE PF BRIEFED THAT APCH. FURTHER IN ON THE ARR, WE WERE REASSIGNED ILS RWY 18R. I ACCEPTED CTL OF THE ACFT FROM THE FO WHILE HE REVIEWED THE APCH AND RETUNED RADIOS. ON A VECTOR TO THE 'VISUAL' TO RWY 18R, WE WERE GIVEN A HDG TO INTERCEPT THE LOC AND CROSS TUFFE AT 2300 FT MSL. ON INTERCEPT HDG, THE FO FINISHED APCH REVIEW AND BEGAN FLYING THE APCH. AFTER I HANDED THE ACFT BACK TO THE FO, I SCANNED THE FE'S PANEL AND THEN MY INSTS. WE INTERCEPTED THE LOC BTWN HAMMI AND TUFFY. I NOTED THE ALT BELOW THE ASSIGNED ALT AND THE GS NEARLY CTRED. I ADVISED FO NOT TO DSND AND TO RETURN TO 2300 FT UNTIL TUFFY. IN HIS CORRECTION FROM APPROX 200 FT LOWER THAN ASSIGNED ALT, HE CLBED TO APPROX 200 FT HIGHER THAN THE 2300 FT XING ALT FOR TUFFY. THIS HIGH DEV HAPPENED SIMULTANEOUSLY WITH XING TUFFY. WITH MY ASSISTANCE, THE APCH WAS STABILIZED AND WE LANDED NORMALLY.
