A computer-based system, the G1000 Trainer also has a memory system that is obviously very useful to its operation. How else would it be able to show accurate information to the private pilot about weather conditions in the area of the flight plan, and the layout of the destination airport?
All of these information are stored in SD memory cards. The G1000 system uses a total of four SD cards. Two cards go to the primary flight display, while the other pair is for the multi-function display. There are two slots in which they go to for each display: the top slot and the bottom slot. The former is used as a means of updating the Jeppesen aviation database, which is very crucial to flying. The bottom card can be used to download updated information on the databases for the world terrain and Jeppesen obstacles.
Updating the Cards
The data on the memory card needs to be updated regularly. If not, then you would not have access to really accurate information when you learn to fly with the G1000 trainer, and that can prove to be costly for you.
How often must you update the cards? That would depend. The Jeppesen aviation database has to be updated every 28 days, because several new information could appear and be useful to your private pilot flight training within that span of time. As for the Jeppesen obstacle and World Terrain databases, the period between one update and the other spans 56 days; twice that for the Jeppesen aviation database.
How to Update the Cards?
Each card slot also has different ways of being updated. The bottom cards can only be updated through a subscription service.
The top cards, on the other hand, can be updated by downloading the information through the Garmin website. This would require you to register into an account. After logging in to your account, you can now download updated information for your Jeppesen database. You also need to select your aircraft type and the Garmin device in it – in this case the G1000 – as well as install the Jeppesen Services Update Manager on your computer. Once these are done, download updated NavData unto each of the cards and transfer them to your aircraft’s G1000.
To update the databases on your G1000, you only need to insert the memory cards into their respective slots, turn on the Master Power Switch, allow the databases to update itself then turn off the Master Power Switch. You only need to do this once for the lower cards, but you have to do the process individually for each upper slots.
