GPS database updates
GPS Nav databases update every 28 days on Thursday. One week before they expire, the new database is made available. We typically download the update and put the card in the airplanes before the old ones expire which automatically copies the database into the GPS under "Standy". Before flying IFR you will want to make sure the database is current.
Typically, the GPS will prompt you to update the database when you turn it on after the current database expires. If it does not, there are two ways to force the update.
One is to hold the nav frequency knob while powering up the GPS to force the prompt. Alternatively, you can go under settings to find the standby database and upload it as current.
