What is the Jeppesen data?
The Jeppesen data consists of: NavData®: Airports, runways, frequencies, navaids, controlled airspace and restricted airspace. Obstacle data: Depiction of the location and height of man-made obstacles that extend above the ground. Cultural data: Contains boundary and reference information for countries, other major political subdivisions, large water bodies, coastlines, time zones, and other physical and political features. Terrain data: Data that depicts the contours and shapes of the surface of the earth. The 3 arc second terrain database, mainly due to the large file size, lives on the micro SD card that loads into the front of the EFD display. The terrain data will only be updated on an as needed basis and is not a part of the normal 28-day data update cycle from Jeppesen.
