Narrative:

Deviation from SID. I was the PF on climb out from ont on the pom 6 departure. We were on a 255 degree heading to intercept the pom 114 degree radial as depicted on the SID. We were climbing through approximately 4000 ft cleared to 14000 ft with the 8000 ft restr at pom. I was hand flying the aircraft in navigation mode and was about to engage the autoplt and LNAV when the captain stated 'you are going through the course.' the FMC had not directed the turn as of yet. I thought I must have had a problem with the FMC and turned to a heading of 300 degrees to intercept the 114 degree radial to pom. As I was turning, I selected VOR/ILS on the mode controller and instantly verified by the CDI and rmt that we had not gone through the course and had not begun to intercept the 114 degree radial. I turned back to 255 degrees to reintercept at which time it was determined the #1 navigation was not tuned to pom. The departure controller queried us as to what our heading was and the captain reported that we were back on the 255 degree heading. The controller then stated 'that's not the way the pom 6 is flown' and assigned us a 300 degree heading and eventually handed us off to ZLA. The rest of the flight was without incident. In retrospect when I briefed the departure, I should have verified that both navigation's were tuned correctly and again asked the captain to back me up with VOR when I went to navigation mode which should have prompted him to make sure he was set up for the departure correctly. My second mistake was to just arbitrarily turn when he said we were going through the course without reverifying our position with my equipment which was giving us the correct information. I personally feel that using the FMC and LNAV is the best way to fly a SID or STAR as is our procedure in flying RNAV specific arrs and departures. Had I continued to do so on this departure there wouldn't have been a problem. We as a crew thought we were backing each other up correctly, but I reacted too quickly to the captain's perception that we were wrong. I will be much more thorough in checking that both sides of the cockpit are set up correctly and in briefing my fellow crew member on how I plan to fly a particular procedure. Our situational awareness was degraded by one mis-tuned radio. Supplemental information from acn 563643: my navigation receiver was inadvertently set to the wrong frequency. This resulted in an erroneous course indication. I crosschecked the first officer's course indicator and discovered that he was operating in the LNAV mode. Since he had not briefed me on LNAV usage on a non RNAV departure, I assumed that he also had made an error in setting up his navigation radio and course for the departure. This problem occurred as a result of improper LNAV usage and my failure to properly set my navigation receiver for the departure. I believe we need a more coordinated set of procedures for LNAV and MCP usage to keep both pilots 'in the loop.' this can be accomplished by the PF commanding MCP modes and the PNF making the MCP selection and making a vocal announcement of the selection.

Title: HDG TRACK DEV ON THE POM 6 SID FROM ONT WHEN THE PIC HAS THE WRONG VOR TUNED IN FOR CAPTURING THE 114 DEG RADIAL OF POM, CA.

Narrative: DEV FROM SID. I WAS THE PF ON CLBOUT FROM ONT ON THE POM 6 DEP. WE WERE ON A 255 DEG HDG TO INTERCEPT THE POM 114 DEG RADIAL AS DEPICTED ON THE SID. WE WERE CLBING THROUGH APPROX 4000 FT CLRED TO 14000 FT WITH THE 8000 FT RESTR AT POM. I WAS HAND FLYING THE ACFT IN NAV MODE AND WAS ABOUT TO ENGAGE THE AUTOPLT AND LNAV WHEN THE CAPT STATED 'YOU ARE GOING THROUGH THE COURSE.' THE FMC HAD NOT DIRECTED THE TURN AS OF YET. I THOUGHT I MUST HAVE HAD A PROB WITH THE FMC AND TURNED TO A HDG OF 300 DEGS TO INTERCEPT THE 114 DEG RADIAL TO POM. AS I WAS TURNING, I SELECTED VOR/ILS ON THE MODE CTLR AND INSTANTLY VERIFIED BY THE CDI AND RMT THAT WE HAD NOT GONE THROUGH THE COURSE AND HAD NOT BEGUN TO INTERCEPT THE 114 DEG RADIAL. I TURNED BACK TO 255 DEGS TO REINTERCEPT AT WHICH TIME IT WAS DETERMINED THE #1 NAV WAS NOT TUNED TO POM. THE DEP CTLR QUERIED US AS TO WHAT OUR HDG WAS AND THE CAPT RPTED THAT WE WERE BACK ON THE 255 DEG HDG. THE CTLR THEN STATED 'THAT'S NOT THE WAY THE POM 6 IS FLOWN' AND ASSIGNED US A 300 DEG HDG AND EVENTUALLY HANDED US OFF TO ZLA. THE REST OF THE FLT WAS WITHOUT INCIDENT. IN RETROSPECT WHEN I BRIEFED THE DEP, I SHOULD HAVE VERIFIED THAT BOTH NAV'S WERE TUNED CORRECTLY AND AGAIN ASKED THE CAPT TO BACK ME UP WITH VOR WHEN I WENT TO NAV MODE WHICH SHOULD HAVE PROMPTED HIM TO MAKE SURE HE WAS SET UP FOR THE DEP CORRECTLY. MY SECOND MISTAKE WAS TO JUST ARBITRARILY TURN WHEN HE SAID WE WERE GOING THROUGH THE COURSE WITHOUT REVERIFYING OUR POS WITH MY EQUIP WHICH WAS GIVING US THE CORRECT INFO. I PERSONALLY FEEL THAT USING THE FMC AND LNAV IS THE BEST WAY TO FLY A SID OR STAR AS IS OUR PROC IN FLYING RNAV SPECIFIC ARRS AND DEPS. HAD I CONTINUED TO DO SO ON THIS DEP THERE WOULDN'T HAVE BEEN A PROB. WE AS A CREW THOUGHT WE WERE BACKING EACH OTHER UP CORRECTLY, BUT I REACTED TOO QUICKLY TO THE CAPT'S PERCEPTION THAT WE WERE WRONG. I WILL BE MUCH MORE THOROUGH IN CHKING THAT BOTH SIDES OF THE COCKPIT ARE SET UP CORRECTLY AND IN BRIEFING MY FELLOW CREW MEMBER ON HOW I PLAN TO FLY A PARTICULAR PROC. OUR SITUATIONAL AWARENESS WAS DEGRADED BY ONE MIS-TUNED RADIO. SUPPLEMENTAL INFO FROM ACN 563643: MY NAV RECEIVER WAS INADVERTENTLY SET TO THE WRONG FREQ. THIS RESULTED IN AN ERRONEOUS COURSE INDICATION. I XCHKED THE FO'S COURSE INDICATOR AND DISCOVERED THAT HE WAS OPERATING IN THE LNAV MODE. SINCE HE HAD NOT BRIEFED ME ON LNAV USAGE ON A NON RNAV DEP, I ASSUMED THAT HE ALSO HAD MADE AN ERROR IN SETTING UP HIS NAV RADIO AND COURSE FOR THE DEP. THIS PROB OCCURRED AS A RESULT OF IMPROPER LNAV USAGE AND MY FAILURE TO PROPERLY SET MY NAV RECEIVER FOR THE DEP. I BELIEVE WE NEED A MORE COORDINATED SET OF PROCS FOR LNAV AND MCP USAGE TO KEEP BOTH PLTS 'IN THE LOOP.' THIS CAN BE ACCOMPLISHED BY THE PF COMMANDING MCP MODES AND THE PNF MAKING THE MCP SELECTION AND MAKING A VOCAL ANNOUNCEMENT OF THE SELECTION.
