Narrative:

Aircraft navigation database defaults to incorrect altitude on the missed approach on all the ILS runway 16's at sea. It codes 2000A (2000 ft or above) at the first waypoint and according to the plate it should 2000B (2000 ft or below). I have seen this in multiple aircraft.callback conversation with reporter revealed the following information: the reporter stated that the aircraft in question is a B737-400 but believes that the problem may exist on other models that he flies. A missed approach flown using VNAV and LNAV would likely exceed the 2000 ft restriction under most circumstances.

Original NASA ASRS Text

Title: B737-400 CAPTAIN REPORTS NAVIGATION DATABASE HAS INCORRECT CROSSING RESTRICTION ON ALL ILS MISSED APPROACHES TO THE SOUTH RUNWAYS AT SEA. ON RWY 16L; TEBNE IS CODED AS 2000A AND SHOULD BE CODED AS 2000B.

Narrative: AIRCRAFT NAV DATABASE DEFAULTS TO INCORRECT ALTITUDE ON THE MISSED APPROACH ON ALL THE ILS RWY 16'S AT SEA. IT CODES 2000A (2000 FT OR ABOVE) AT THE FIRST WAYPOINT AND ACCORDING TO THE PLATE IT SHOULD 2000B (2000 FT OR BELOW). I HAVE SEEN THIS IN MULTIPLE AIRCRAFT.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT THE AIRCRAFT IN QUESTION IS A B737-400 BUT BELIEVES THAT THE PROBLEM MAY EXIST ON OTHER MODELS THAT HE FLIES. A MISSED APPROACH FLOWN USING VNAV AND LNAV WOULD LIKELY EXCEED THE 2000 FT RESTRICTION UNDER MOST CIRCUMSTANCES.
