They rarely change the low altitudes- you need to look at the chart notams
in the revision cycles to see if there are any changes. The Jepp lows are
flimsy, and for a few extra dollars I subscribe to the FAA charts, which are
larger scale, more durable, and are replaced on a regular basis.

Right.. I get the white boxes every 56 days. I was wondering about the
low altitudes. Can I still use the one that Jeppesen had sent me
initially, or do I need to have a separate subscription.
