Hello:
I just wonder if there is a place where you can check which is the last date
changed were made to a Jepp approach chart of Low-Altitude Enroute Chart.
Our club has 49 / 50 enroute charts, that are supposed to be current (last
changed Jul 04), but I found out a frequency was wrong. How do I find out if
we need to get a new chart from Jepp, or if that is the last chart but has
an error.

thanks

Jeppesen lets their en route charts get out-of-date until they feel a new
issuance is necessary. In the meantime, you have to keep checking all their
chart notams.

Or, if you have JeppView/FliteDeck, those en route charts are updated I believe
every 28 days.
