Narrative:

This situation began when we were issued the following clearance from scottsdale ground control: ATC clears us to hou, after departure fly a 260 degree heading to intercept salt river 325 degree radial to the 36 DME fix, then vectors to tfd 133 degree radial to intercept the gbn 96 degree radial to intercept the cie 278 degree radial dir sso as filed. Maintain 5000', expect 16000' in 3 mins, 41000' in 10 mins, departure on 121.7 squawk 0721. After departing we turned left to 260 degrees, then contacted phx departure who gave us vectors and climb clearance. Then, later clrd us dir tfd. Upon reaching tfd we turned in error to 93 degrees outbnd instead of 133 degrees. Approximately 1 min later center asked us our heading and wanted to know why we were not on the standfield 1 high departure, to which we replied that we departed from sdl, not phx. At that point we realized we should be on the 133 degree radial, not the 93 degree radial of tfd. As soon as we corrected our course ATC told us to go dir sso and climb to 41000'. To our best estimate, we at no time exceeded 4 mi off course. I believe the clearance we received at sdl was entirely too confusing and takes too much time for the flight crew to fly west/O the use of an SID plate. I would highly recommend that if it is necessary to use this procedure when departing sdl, that ATC have a published SID procedure. Supplemental information from acn 80813: I believe clearance from sdl very complicated and uncalled for. They should have a SID published. I would like to see somebody fly that after a total radio failure in IMC.

Title: CORP JET FLT CREW GOT OFF CLEARED ROUTE DURING COMPLICATED DEP PROC.

Narrative: THIS SITUATION BEGAN WHEN WE WERE ISSUED THE FOLLOWING CLRNC FROM SCOTTSDALE GND CTL: ATC CLRS US TO HOU, AFTER DEP FLY A 260 DEG HDG TO INTERCEPT SALT RIVER 325 DEG RADIAL TO THE 36 DME FIX, THEN VECTORS TO TFD 133 DEG RADIAL TO INTERCEPT THE GBN 96 DEG RADIAL TO INTERCEPT THE CIE 278 DEG RADIAL DIR SSO AS FILED. MAINTAIN 5000', EXPECT 16000' IN 3 MINS, 41000' IN 10 MINS, DEP ON 121.7 SQUAWK 0721. AFTER DEPARTING WE TURNED LEFT TO 260 DEGS, THEN CONTACTED PHX DEP WHO GAVE US VECTORS AND CLB CLRNC. THEN, LATER CLRD US DIR TFD. UPON REACHING TFD WE TURNED IN ERROR TO 93 DEGS OUTBND INSTEAD OF 133 DEGS. APPROX 1 MIN LATER CENTER ASKED US OUR HDG AND WANTED TO KNOW WHY WE WERE NOT ON THE STANDFIELD 1 HIGH DEP, TO WHICH WE REPLIED THAT WE DEPARTED FROM SDL, NOT PHX. AT THAT POINT WE REALIZED WE SHOULD BE ON THE 133 DEG RADIAL, NOT THE 93 DEG RADIAL OF TFD. AS SOON AS WE CORRECTED OUR COURSE ATC TOLD US TO GO DIR SSO AND CLB TO 41000'. TO OUR BEST ESTIMATE, WE AT NO TIME EXCEEDED 4 MI OFF COURSE. I BELIEVE THE CLRNC WE RECEIVED AT SDL WAS ENTIRELY TOO CONFUSING AND TAKES TOO MUCH TIME FOR THE FLT CREW TO FLY W/O THE USE OF AN SID PLATE. I WOULD HIGHLY RECOMMEND THAT IF IT IS NECESSARY TO USE THIS PROC WHEN DEPARTING SDL, THAT ATC HAVE A PUBLISHED SID PROC. SUPPLEMENTAL INFORMATION FROM ACN 80813: I BELIEVE CLRNC FROM SDL VERY COMPLICATED AND UNCALLED FOR. THEY SHOULD HAVE A SID PUBLISHED. I WOULD LIKE TO SEE SOMEBODY FLY THAT AFTER A TOTAL RADIO FAILURE IN IMC.
