Narrative:

Pursuant to air carrier recommended procedures, PF (copilot) was on FMC using map mode of HSI while I, as PNF, was on raw data using VOR mode of HSI. Departure procedure calls for turn to a heading of 030 degrees when I DME from srp VOR for vector to the srp 330 degree right. While acting as PNF I noticed copilot turning from 030 degrees to the left since he had the benefit of the FMC and map presentation I assumed he was correct but questioned him about it anyway. He stated that he was turning to intercept the 330 degree right. I then consulted the SID to determine the appropriateness of the turn about that time departure control caught the incorrect turn and put us on a vector. As a consequence of the confusion the, copilot almost busted assigned altitude (I pushed on yoke to stop climb) of 8000' MSL (actually stopped climb at 8280' MSL and immediately descended back to 8000'). After discussing matter with copilot, it was clear that he had thought 030 degree heading was for intercept of srp 330 degrees--not for vector to intercept the 330 degree right. Thought we had briefed SID at the gate and again while holding short just before departure, the copilot's misunderstanding of the terminology had gone unnoticed. In the future, I will (as captain) make sure both pilots understand the exact meaning of the procedure terminology (i.e., more than just reviewing the worms of the procedure, but also the exact meaning of those words to clear up any possible ambiguity). If chart used wording such as 'expect' vector it might be more apparent that heading was not for intercept but rather for expected vector for intercept. Supplemental information from acn 153342: first officer was PF (1 month and 45 hours in aircraft type since initial line check), first captain bid for captain (3 weeks and 50 hours in type since initial time check), first glass cockpit for both pilots. Captain HSI set to full VOR/ILS per company bulletin (map shift problems).

Title: CONFUSION OVER SID PROC FOR ACR MLG FLT CREW AT PHX ON DRAKE 4 DEP LEADS TO TRACK DEVIATION, THEN ALT OVERSHOOT IN CLIMB.

Narrative: PURSUANT TO ACR RECOMMENDED PROCS, PF (COPLT) WAS ON FMC USING MAP MODE OF HSI WHILE I, AS PNF, WAS ON RAW DATA USING VOR MODE OF HSI. DEP PROC CALLS FOR TURN TO A HDG OF 030 DEGS WHEN I DME FROM SRP VOR FOR VECTOR TO THE SRP 330 DEG R. WHILE ACTING AS PNF I NOTICED COPLT TURNING FROM 030 DEGS TO THE LEFT SINCE HE HAD THE BENEFIT OF THE FMC AND MAP PRESENTATION I ASSUMED HE WAS CORRECT BUT QUESTIONED HIM ABOUT IT ANYWAY. HE STATED THAT HE WAS TURNING TO INTERCEPT THE 330 DEG R. I THEN CONSULTED THE SID TO DETERMINE THE APPROPRIATENESS OF THE TURN ABOUT THAT TIME DEP CTL CAUGHT THE INCORRECT TURN AND PUT US ON A VECTOR. AS A CONSEQUENCE OF THE CONFUSION THE, COPLT ALMOST BUSTED ASSIGNED ALT (I PUSHED ON YOKE TO STOP CLB) OF 8000' MSL (ACTUALLY STOPPED CLB AT 8280' MSL AND IMMEDIATELY DSNDED BACK TO 8000'). AFTER DISCUSSING MATTER WITH COPLT, IT WAS CLR THAT HE HAD THOUGHT 030 DEG HDG WAS FOR INTERCEPT OF SRP 330 DEGS--NOT FOR VECTOR TO INTERCEPT THE 330 DEG R. THOUGHT WE HAD BRIEFED SID AT THE GATE AND AGAIN WHILE HOLDING SHORT JUST BEFORE DEP, THE COPLT'S MISUNDERSTANDING OF THE TERMINOLOGY HAD GONE UNNOTICED. IN THE FUTURE, I WILL (AS CAPT) MAKE SURE BOTH PLTS UNDERSTAND THE EXACT MEANING OF THE PROC TERMINOLOGY (I.E., MORE THAN JUST REVIEWING THE WORMS OF THE PROC, BUT ALSO THE EXACT MEANING OF THOSE WORDS TO CLR UP ANY POSSIBLE AMBIGUITY). IF CHART USED WORDING SUCH AS 'EXPECT' VECTOR IT MIGHT BE MORE APPARENT THAT HDG WAS NOT FOR INTERCEPT BUT RATHER FOR EXPECTED VECTOR FOR INTERCEPT. SUPPLEMENTAL INFO FROM ACN 153342: F/O WAS PF (1 MONTH AND 45 HRS IN ACFT TYPE SINCE INITIAL LINE CHK), FIRST CAPT BID FOR CAPT (3 WKS AND 50 HRS IN TYPE SINCE INITIAL TIME CHK), FIRST GLASS COCKPIT FOR BOTH PLTS. CAPT HSI SET TO FULL VOR/ILS PER COMPANY BULLETIN (MAP SHIFT PROBS).
