Narrative:

Upon departing phx on runway 26L using the mobie 3 departure, we failed to turn to the published heading of 240 degrees and instead flew the runway heading of 260 degrees. Although no adverse consequences followed our action, phx tower asked us why we missed the turn. The captain and myself did review the departure before takeoff, however, we missed the turn anyway confusing the departure with the eagle 2 departure in which the published heading is to fly runway heading 26R. We perform both departures frequently and it is my opinion that phx departure procedures are too complicated and confusing. It is much more effective to utilize a departure procedure such as denver uses. Radar vectors to intercept a filed course.

Title: FLC OF AN LTT FAILED TO TURN AFTER TKOF TO THE PUBLISHED SID HDG.

Narrative: UPON DEPARTING PHX ON RWY 26L USING THE MOBIE 3 DEP, WE FAILED TO TURN TO THE PUBLISHED HDG OF 240 DEGS AND INSTEAD FLEW THE RWY HDG OF 260 DEGS. ALTHOUGH NO ADVERSE CONSEQUENCES FOLLOWED OUR ACTION, PHX TWR ASKED US WHY WE MISSED THE TURN. THE CAPT AND MYSELF DID REVIEW THE DEP BEFORE TKOF, HOWEVER, WE MISSED THE TURN ANYWAY CONFUSING THE DEP WITH THE EAGLE 2 DEP IN WHICH THE PUBLISHED HDG IS TO FLY RWY HDG 26R. WE PERFORM BOTH DEPS FREQUENTLY AND IT IS MY OPINION THAT PHX DEP PROCS ARE TOO COMPLICATED AND CONFUSING. IT IS MUCH MORE EFFECTIVE TO UTILIZE A DEP PROC SUCH AS DENVER USES. RADAR VECTORS TO INTERCEPT A FILED COURSE.
