Narrative:
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.
