Narrative:

Matzatlan queried us as to our clearance. When we confirmed it, we noticed that we were on the wrong airway. Upon investigation, we found that the route printed in the clearance strip on the computer flight plan was our 'cleared route of flight.' the route on the computer flight plan, though, had us load 'route 01' in the GPS. We were flying that route. When we looked into the commercial chart standard routes, we found that the route 01 was just what we were flying, however, it wasn't what we were cleared for, and wasn't what was on the clearance strip of the computer flight plan! By the way, the return routing wasn't right either. My suggestion is to correct this error in the en route pages and to warn other aircrews to be ever vigilant as to what we are loading into the 'box.' center had no problem with us 'scooting' over to our assigned airway, but this could be a big problem in the USA airspace!

Title: MD80 FLC HAS WRONG RTE LOADED IN THE GPS AND DOESN'T REALIZE THE MISTAKE UNTIL AIRBORNE.

Narrative: MATZATLAN QUERIED US AS TO OUR CLRNC. WHEN WE CONFIRMED IT, WE NOTICED THAT WE WERE ON THE WRONG AIRWAY. UPON INVESTIGATION, WE FOUND THAT THE RTE PRINTED IN THE CLRNC STRIP ON THE COMPUTER FLT PLAN WAS OUR 'CLRED RTE OF FLT.' THE RTE ON THE COMPUTER FLT PLAN, THOUGH, HAD US LOAD 'RTE 01' IN THE GPS. WE WERE FLYING THAT RTE. WHEN WE LOOKED INTO THE COMMERCIAL CHART STANDARD ROUTES, WE FOUND THAT THE RTE 01 WAS JUST WHAT WE WERE FLYING, HOWEVER, IT WASN'T WHAT WE WERE CLRED FOR, AND WASN'T WHAT WAS ON THE CLRNC STRIP OF THE COMPUTER FLT PLAN! BY THE WAY, THE RETURN ROUTING WASN'T RIGHT EITHER. MY SUGGESTION IS TO CORRECT THIS ERROR IN THE ENRTE PAGES AND TO WARN OTHER AIRCREWS TO BE EVER VIGILANT AS TO WHAT WE ARE LOADING INTO THE 'BOX.' CTR HAD NO PROB WITH US 'SCOOTING' OVER TO OUR ASSIGNED AIRWAY, BUT THIS COULD BE A BIG PROB IN THE USA AIRSPACE!
