Narrative:

Departed phx on silow 1 departure. FMS went into 'dr' mode and lost its position. I figured we had time to fix the FMS before we reached the 9 DME fix. This is where a right turn to 360 degrees is required. My first officer was unable to fix the problem and by the time we went to traditional green needles, we had overflown our fix by 4 mi. I started the turn and at the same time, the ATC controller was quite upset and had us turn to a 045 degree heading. We told the controller of our FMS problem. I then fixed the FMS position status and proceeded with an uneventful flight. The controller had us call reaching slc with a possible 'pilot deviation.' reaching slc, I called the controller. He had already gone home for the day. The ATC controller I spoke with took some time to figure out why I was calling. She finally told me that the controller which was working our flight was upset that we did not 'check in' in a timely manner and that we failed to turn north at the 9 DME fix. I agreed with the late turn and did not comment about checking in on departure frequency. She told me the case was closed. In reviewing my actions, I should have gone to green needles much quicker. I also made the mistake of thinking we had 9 mi from phx and instead, it is from phx, I thought phx VOR was located on the airport. I now have a back-up plan when it comes to pilot navigation sids, especially if the aircraft does not have an FMS, radio frequencys are in standby, and I am ready to quickly go green needles. I am also going to immediately inform ATC -- 'no FMS, can you call my turn?' I also learned that things happen quick in a jet.

Title: CL65 FMS DEFAULTS TO 'DR' MODE AFTER DEPARTING PHX, RESULTING IN A XING RESTR OVERSHOOT ON THE SILOW SID.

Narrative: DEPARTED PHX ON SILOW 1 DEP. FMS WENT INTO 'DR' MODE AND LOST ITS POS. I FIGURED WE HAD TIME TO FIX THE FMS BEFORE WE REACHED THE 9 DME FIX. THIS IS WHERE A R TURN TO 360 DEGS IS REQUIRED. MY FO WAS UNABLE TO FIX THE PROB AND BY THE TIME WE WENT TO TRADITIONAL GREEN NEEDLES, WE HAD OVERFLOWN OUR FIX BY 4 MI. I STARTED THE TURN AND AT THE SAME TIME, THE ATC CTLR WAS QUITE UPSET AND HAD US TURN TO A 045 DEG HDG. WE TOLD THE CTLR OF OUR FMS PROB. I THEN FIXED THE FMS POS STATUS AND PROCEEDED WITH AN UNEVENTFUL FLT. THE CTLR HAD US CALL REACHING SLC WITH A POSSIBLE 'PLTDEV.' REACHING SLC, I CALLED THE CTLR. HE HAD ALREADY GONE HOME FOR THE DAY. THE ATC CTLR I SPOKE WITH TOOK SOME TIME TO FIGURE OUT WHY I WAS CALLING. SHE FINALLY TOLD ME THAT THE CTLR WHICH WAS WORKING OUR FLT WAS UPSET THAT WE DID NOT 'CHK IN' IN A TIMELY MANNER AND THAT WE FAILED TO TURN N AT THE 9 DME FIX. I AGREED WITH THE LATE TURN AND DID NOT COMMENT ABOUT CHKING IN ON DEP FREQ. SHE TOLD ME THE CASE WAS CLOSED. IN REVIEWING MY ACTIONS, I SHOULD HAVE GONE TO GREEN NEEDLES MUCH QUICKER. I ALSO MADE THE MISTAKE OF THINKING WE HAD 9 MI FROM PHX AND INSTEAD, IT IS FROM PHX, I THOUGHT PHX VOR WAS LOCATED ON THE ARPT. I NOW HAVE A BACK-UP PLAN WHEN IT COMES TO PLT NAV SIDS, ESPECIALLY IF THE ACFT DOES NOT HAVE AN FMS, RADIO FREQS ARE IN STANDBY, AND I AM READY TO QUICKLY GO GREEN NEEDLES. I AM ALSO GOING TO IMMEDIATELY INFORM ATC -- 'NO FMS, CAN YOU CALL MY TURN?' I ALSO LEARNED THAT THINGS HAPPEN QUICK IN A JET.
