Narrative:
We were on an ILS approach to runway 25L to lax. The company had requested an autoland approach and landing so the aircraft was on autoplt for the autoland. We were slowed several times on the approach and were told to cross 'hunda' intersection at 3500 ft. We were on or above the GS until 'gaate' intersection and on the GS from 'gaate' intersection to touchdown. Hunda is not depicted on our FMS, but we figured it to be 4.8 mi from 'limma' intersection which is depicted. We crossed 4.8 mi from 'limma' (hunda) at 3460 ft to 3500 ft. Rest of approach was normal with a normal autoland touchdown. We believe we did everything as requested, however, we were told to contact socal approach control by telephone. When I did I was told they would check their equipment tomorrow and would contact me if any action was to be taken against me due to GS deviation. I do believe 'hunda' intersection should be depicted on our FMS rather than having to figure it out on approach.
Original NASA ASRS Text
Title: B757 ACFT ON ILS AUTOLAND APCH WAS INSTRUCTED TO CROSS INTXN AT 3500 FT. FLC HAD ENGAGED AUTOLAND AND WERE ON GS WHICH TOOK ACFT BELOW RESTR ALT.
Narrative: WE WERE ON AN ILS APCH TO RWY 25L TO LAX. THE COMPANY HAD REQUESTED AN AUTOLAND APCH AND LNDG SO THE ACFT WAS ON AUTOPLT FOR THE AUTOLAND. WE WERE SLOWED SEVERAL TIMES ON THE APCH AND WERE TOLD TO CROSS 'HUNDA' INTXN AT 3500 FT. WE WERE ON OR ABOVE THE GS UNTIL 'GAATE' INTXN AND ON THE GS FROM 'GAATE' INTXN TO TOUCHDOWN. HUNDA IS NOT DEPICTED ON OUR FMS, BUT WE FIGURED IT TO BE 4.8 MI FROM 'LIMMA' INTXN WHICH IS DEPICTED. WE CROSSED 4.8 MI FROM 'LIMMA' (HUNDA) AT 3460 FT TO 3500 FT. REST OF APCH WAS NORMAL WITH A NORMAL AUTOLAND TOUCHDOWN. WE BELIEVE WE DID EVERYTHING AS REQUESTED, HOWEVER, WE WERE TOLD TO CONTACT SOCAL APCH CTL BY TELEPHONE. WHEN I DID I WAS TOLD THEY WOULD CHK THEIR EQUIP TOMORROW AND WOULD CONTACT ME IF ANY ACTION WAS TO BE TAKEN AGAINST ME DUE TO GS DEV. I DO BELIEVE 'HUNDA' INTXN SHOULD BE DEPICTED ON OUR FMS RATHER THAN HAVING TO FIGURE IT OUT ON APCH.
