Navdata currency question

The current Jepp cycle expires the 17th and the next card becomes
effective the 18th. My question is -- can I buy the newer card (which
becomes effective the 18th) and use it on the 15th, BEFORE the effective
date on the card.

Regarding Jepp charts and GNS x30 database subscriptions, I have learned
that any approach procedures that changed with that upcoming cycle and have
an effective date greater than the date the database and paper charts are
released will have the effective date printed on the approach plate itself.
Thus, if you have the paper charts in front of you, you can quickly
determine what is and what will be effective.

A little bit of pre-flight planning should provide you with the answers to
what you can rely on immediately from the database itself.
