Narrative:

There is a discrepancy between the MEA on page 10-2A puerto vallarta, mexico, arrs runway 22 dated jan/xx/95 and page 10-1 for guadalajara, mexico, dated jan/xx/95. On page 10-2A from a point at comal on V14 into pvr 20 DME on 086 degree radial off of pvr, it shows an MEA of 11000 ft which is also reflected in our database. On page 10-1 guadalajara from the same point inbound to pvr the MEA shows up as 13000 ft. We flew the approach and changed our FMS to reflect 13000 ft versus 11000 ft. I don't know if pvr has a page 10-1, but it would help in terrain avoidance if we had a page 10-1 available that reflected the city we were going into, rather than having to look up another city. Callback conversation with reporter revealed the following information: the reporter flies the A320 airbus to puerto vallarta on a seasonal basis. His air carrier does not serve guadalajara, and it is inconvenient for him to have to refer to a page 10-1 for another airport to go to pvr. He believes that the producer of the commercial airport pages and the database may have made a mistake with the 11000 ft MEA west of comal on the arrival page 10-2A. The mountains are very impressive in this neighborhood, and the reporter believes that the radar service is very poor. A call to the provider of the commercial charts and data base found that the reporter's pilot union has raised the question about the minimum altitudes. Mexico was asked about the discrepancy, and mexico says that the altitudes are correct as is. The higher altitudes are for overflts while the lower altitudes are for the arrs into pvr.

Title: AERO CHART PRESENTATION.

Narrative: THERE IS A DISCREPANCY BTWN THE MEA ON PAGE 10-2A PUERTO VALLARTA, MEXICO, ARRS RWY 22 DATED JAN/XX/95 AND PAGE 10-1 FOR GUADALAJARA, MEXICO, DATED JAN/XX/95. ON PAGE 10-2A FROM A POINT AT COMAL ON V14 INTO PVR 20 DME ON 086 DEG RADIAL OFF OF PVR, IT SHOWS AN MEA OF 11000 FT WHICH IS ALSO REFLECTED IN OUR DATABASE. ON PAGE 10-1 GUADALAJARA FROM THE SAME POINT INBOUND TO PVR THE MEA SHOWS UP AS 13000 FT. WE FLEW THE APCH AND CHANGED OUR FMS TO REFLECT 13000 FT VERSUS 11000 FT. I DON'T KNOW IF PVR HAS A PAGE 10-1, BUT IT WOULD HELP IN TERRAIN AVOIDANCE IF WE HAD A PAGE 10-1 AVAILABLE THAT REFLECTED THE CITY WE WERE GOING INTO, RATHER THAN HAVING TO LOOK UP ANOTHER CITY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR FLIES THE A320 AIRBUS TO PUERTO VALLARTA ON A SEASONAL BASIS. HIS ACR DOES NOT SERVE GUADALAJARA, AND IT IS INCONVENIENT FOR HIM TO HAVE TO REFER TO A PAGE 10-1 FOR ANOTHER ARPT TO GO TO PVR. HE BELIEVES THAT THE PRODUCER OF THE COMMERCIAL ARPT PAGES AND THE DATABASE MAY HAVE MADE A MISTAKE WITH THE 11000 FT MEA W OF COMAL ON THE ARR PAGE 10-2A. THE MOUNTAINS ARE VERY IMPRESSIVE IN THIS NEIGHBORHOOD, AND THE RPTR BELIEVES THAT THE RADAR SVC IS VERY POOR. A CALL TO THE PROVIDER OF THE COMMERCIAL CHARTS AND DATA BASE FOUND THAT THE RPTR'S PLT UNION HAS RAISED THE QUESTION ABOUT THE MINIMUM ALTS. MEXICO WAS ASKED ABOUT THE DISCREPANCY, AND MEXICO SAYS THAT THE ALTS ARE CORRECT AS IS. THE HIGHER ALTS ARE FOR OVERFLTS WHILE THE LOWER ALTS ARE FOR THE ARRS INTO PVR.
