Narrative

DEPARTED PHX ON A MOBILE 1 DEP TO SAN. DEP CTL ISSUED US A 180 HDG TO INTERCEPT THE DEP (GBN 055 INBOUND RADIAL) AND CLB TO 13000. ATTEMPTED TO ENTER AN 'INTERCEPT LEG.' ENTRY INTO THE FMC WHEN IT WAS DISCOVERED THAT THE FMC RTE HAD BEEN ENTERED INCORRECTLY. THE CAPT REENTERED THE RTE WHILE I CONTINUED TO HAND FLY THE ACFT. I SELECTED VOR/LOC MODE ON THE FLT DIRECTOR AND THE CAPT ALSO CHKED THIS TO ENSURE I WAS NOT USING BAD FMC INFO. I INTERCEPTED THE RADIAL AND REALIZED MY MISTAKE JUST AS DEP CALLED. I HAD NEVER SWITCHED THE VOR FREQ AND HAD INTERCEPTED THE SRP 235 RADIAL. DEP HAD US STOP OUR CLB AT 10000 FT; WHICH WE WERE JUST PASSING THROUGH. WE PEAKED OUT AT ABOUT 10200. WE PASSED UNDERNEATH A COMPANY ACFT ON DOWNWIND AT 11000. WE BOTH HAD EACH OTHER IN SIGHT. DEP THEN ISSUED US A 160 HDG TO JOIN THE RADIAL; WHICH WE DID RIGHT THIS TIME. A COUPLE OF MISTAKES ON MY PART: 1) MISENTERED THE RTE IN THE FMC ON THE GND IN PHX. 2) GOT DISTR WHILE THE CAPT FIXED MY ORIGINAL MISTAKE AND THEN MADE A BIGGER; STUPIDER MISTAKE. THE ONLY OTHER COMMENT I WOULD ADD IS ABOUT DEP PROCS. THIS IS NOT AN UNCOMMON MISTAKE. DURING THIS 3 DAY TRIP I WILL FLY 13 DEPS INCLUDING 10 DIFFERENT SIDS. TOO MANY DIFFERENT DEPS WITH TOO MANY DIFFERENT VORS; ALTS; RESTRICTIONS; ETC; ETC. SOME ARE SO COMPLEX THEY ARE VERY HARD TO READ AND EXTRAPOLATE THE IMPORTANT INFO. THIS WASN'T THE FIRST TIME THIS HAS HAPPENED; IT WON'T BE THE LAST.
