The new procedure for UM423 says 'Between GNA and BVI proceed south along route to BVI and descend to 10;000 feet. Continue south along UM402 to MAO.'Along that route near KAV the grid MORA's (Minimum Off-Route Altitudes) are 15;200 feet. One revision reflects that the other database should be updated.
The charted altitudes on UM423 between GNA and BVI differ between two sets of information. One shows the MORA (Minimum Off-Route Altitude) to be 15200 feet and the other says to descend to 10000 feet.
