IAI 1124 FLT CREW DEVIATES FROM PUBLISHED DEP RTE ON ZIASE TWO DEP FROM SAF.

Narrative

DEPARTING SAF ON THE ZAISE2 DEP THE SID CALLED FOR AN INTERCEPT OF THE SAF 255 DEG RADIAL TO JOIN THE DEP. THIS TURN WAS MISSED AND THE CAPT CONTINUED ON RWY HEADING OF 200 DEGS AND A CLB TO 10000 FT MSL. AFTER PASSING THE REQUIRED TURN ZAB ADVISED US OF THE MISSED TURN AND ISSUED A TURN TO 250 DEGS AND CLB TO 12000 FT FOR TERRAIN. REMAINDER OF FLT WAS UNEVENTFUL. EVENTS THAT I FEEL CONTRIBUTED TO THIS SIT STEM FROM THE CAPT (PF) NOT UNDERSTANDING THE ATC CLRNC AND SID WHICH HE RECEIVED FROM SAF TWR AND SUBSEQUENTLY BRIEFED ME IN ERROR. THE INITIAL CLRNC INCLUDED THE DEP SID; BUT TO JOIN V263 TO ABQ. THE CAPT BRIEFED ME ON THE SID; BUT HE SAID THE CLRNC WAS TO JOIN V263 S OF ZAISE INTXN TO ABQ PROBABLY DUE IN PART THAT ON THE SID THE 255 DEG RADIAL FROM SAF TO ZAISE INTXN IS NOT LABELED AS V263. REGARDLESS; THE SID DOES STATE TO INTERCEPT THE 255 DEG RADIAL FROM SAF; AND THE CAPT DID NOT REF THE LOW ALT CHART TO VERIFY THE MAKEUP OF V263. I DID QUESTION THIS CLRNC IN THE TKOF BRIEFING DUE TO MY CONCERNS OF FLYING IN MOUNTAINOUS TERRAIN. THE CAPT THEN STATED TO ME THAT IT WAS RADAR VECTORS AFTER THE RWY HEADING TO JOIN THE V263 S OF ZAISE INTXN. THIS WAS APPARENTLY WRONG AND HIS FULL UNDERSTANDING OF THE CLRNC WAS FLAWED FROM THE BEGINNING; BUT WAS RELAYED TO ME IN ERROR AS WELL. THIS EVENT I THINK STEMS FROM COMPLACENCY OF A 'SEA LEVEL' PLT NOT FULLY UNDERSTANDING THE NEED TO BE ERROR FREE IN FLYING IN MOUNTAINOUS TERRAIN. THE CAPT THOUGHT HE WAS RIGHT IN HIS UNDERSTANDING OF THE CLRNC AND I HAD A GUT FEELING THAT IT WAS WRONG; BUT LET MY TRUST IN THE CAPT AND HIS UNDERSTANDING OF THE CLRNC WIN. A CONTRIBUTING FACTOR IS THE LABELING ON THE SID ITSELF. V263 AND V62 ARE LABELED BUT THE 255 DEG RADIAL SHOULD BE LABELED AS WELL AS V263 FOR REF; BUT IS NOT. ALSO; THE CTLR ISSUING THE CLRNC SHOULD REF ONLY THE SID IN THE IFR CLRNC AND AVOID THE USE OF THE V263 INTERCEPT. I ALSO SHOULD TRUST MY INSTINCTS WHEN ANY CLRNC IS IN DOUBT; AND WHEN IN DOUBT ASK AND VERIFY FROM ATC WHAT IS EXACTLY EXPECTED OF US.
