Narrative:

Border 4 departure from san. Normal takeoff till 400 ft MSL, map shift of 43.7 NM occurred. Lost situational awareness followed flight director. Start left turn at 4 DME instead of 19 DME. Departure controller issued radar vectors. Reverted to manual on VOR mode and flew to destination. At cruise altitude, I discovered that I entered sna latitude and longitude on the position page of the FMS instead of san latitude and longitude. On climb at 400 ft, FMS update with vors caused map shift. In the future I will be doublechking latitude and longitude very, very carefully.

Title: B757 ON BORDER 4 SID GOT A MAP SHIFT OF 43 PT 7 MI AT 400 FT. DEP CTLR VECTORED TO COURSE. REVERTED TO MANUAL ON VOR MODE REMAINDER OF FLT. AT CRUISE ALT FOUND HAD USED LATITUDE AND LONGITUDE FOR SNA VERSUS SAN.

Narrative: BORDER 4 DEP FROM SAN. NORMAL TKOF TILL 400 FT MSL, MAP SHIFT OF 43.7 NM OCCURRED. LOST SITUATIONAL AWARENESS FOLLOWED FLT DIRECTOR. START L TURN AT 4 DME INSTEAD OF 19 DME. DEP CTLR ISSUED RADAR VECTORS. REVERTED TO MANUAL ON VOR MODE AND FLEW TO DEST. AT CRUISE ALT, I DISCOVERED THAT I ENTERED SNA LATITUDE AND LONGITUDE ON THE POS PAGE OF THE FMS INSTEAD OF SAN LATITUDE AND LONGITUDE. ON CLB AT 400 FT, FMS UPDATE WITH VORS CAUSED MAP SHIFT. IN THE FUTURE I WILL BE DOUBLECHKING LATITUDE AND LONGITUDE VERY, VERY CAREFULLY.
