Narrative:

While en route to klas, we were flying the skebr RNAV 1 arrival. Before reaching kepec intersection, we were cleared direct to ipumy intersection and told to expect runway 19R at klas. The skebr 1 arrival appears overly complicated and is somewhat confusing. Prior to reaching ipumy, I programmed the FMS for a runway 19R GPS approach. Ipumy was the start of the GPS approach. Being unfamiliar with the procedures at klas, I was thinking they would clear us for a right downwind for runway 19R. Wrong, I should have read the fine print, which would have kept me from writing this report. At ipumy, I activated the GPS runway 19R approach and started a turn north, thinking they would clear us for a visual approach with a right downwind for runway 19R. We were asked where we were going and when were told to make an immediate right turn direct povoc. I was unsure about turning left at ipumy and should have questioned approach control. Originally, we had the FMS programmed for a runway 25L approach. It just didn't make sense to overfly the airport and make a landing on runway 19R and also overfly the approach to runway 19L. Also, with intersection husol closer to runway 19R, it made more sense to head that direction. At most large airports, you don't overfly runways or approachs to runways. As of jan/fri/03, a revision to the skebr 1 arrival is the skebr 2 arrival, which eliminates husol , nelle, napse, condy, and other intxns. Ipumy, povok, and kimme are still there. A lot less confusing. After speaking with the supervisor of approach control, numerous other pilots have had the same confusion. I learned you have to read the fine print of the arrival and not just the diagram.

Title: A CHALLENGER 604 CAPT RPTED A TRACK DEV DURING APCH TO LAS WHILE ON THE SKEBR RNAV ARR.

Narrative: WHILE ENRTE TO KLAS, WE WERE FLYING THE SKEBR RNAV 1 ARR. BEFORE REACHING KEPEC INTXN, WE WERE CLRED DIRECT TO IPUMY INTXN AND TOLD TO EXPECT RWY 19R AT KLAS. THE SKEBR 1 ARR APPEARS OVERLY COMPLICATED AND IS SOMEWHAT CONFUSING. PRIOR TO REACHING IPUMY, I PROGRAMMED THE FMS FOR A RWY 19R GPS APCH. IPUMY WAS THE START OF THE GPS APCH. BEING UNFAMILIAR WITH THE PROCS AT KLAS, I WAS THINKING THEY WOULD CLR US FOR A R DOWNWIND FOR RWY 19R. WRONG, I SHOULD HAVE READ THE FINE PRINT, WHICH WOULD HAVE KEPT ME FROM WRITING THIS RPT. AT IPUMY, I ACTIVATED THE GPS RWY 19R APCH AND STARTED A TURN N, THINKING THEY WOULD CLR US FOR A VISUAL APCH WITH A R DOWNWIND FOR RWY 19R. WE WERE ASKED WHERE WE WERE GOING AND WHEN WERE TOLD TO MAKE AN IMMEDIATE R TURN DIRECT POVOC. I WAS UNSURE ABOUT TURNING L AT IPUMY AND SHOULD HAVE QUESTIONED APCH CTL. ORIGINALLY, WE HAD THE FMS PROGRAMMED FOR A RWY 25L APCH. IT JUST DIDN'T MAKE SENSE TO OVERFLY THE ARPT AND MAKE A LNDG ON RWY 19R AND ALSO OVERFLY THE APCH TO RWY 19L. ALSO, WITH INTXN HUSOL CLOSER TO RWY 19R, IT MADE MORE SENSE TO HEAD THAT DIRECTION. AT MOST LARGE ARPTS, YOU DON'T OVERFLY RWYS OR APCHS TO RWYS. AS OF JAN/FRI/03, A REVISION TO THE SKEBR 1 ARR IS THE SKEBR 2 ARR, WHICH ELIMINATES HUSOL , NELLE, NAPSE, CONDY, AND OTHER INTXNS. IPUMY, POVOK, AND KIMME ARE STILL THERE. A LOT LESS CONFUSING. AFTER SPEAKING WITH THE SUPVR OF APCH CTL, NUMEROUS OTHER PLTS HAVE HAD THE SAME CONFUSION. I LEARNED YOU HAVE TO READ THE FINE PRINT OF THE ARR AND NOT JUST THE DIAGRAM.
