Garmin G1000
The Garmin G1000 is an integrated flight instrument system manufactured by Garmin typically composed of two display units, one serving as a primary flight display, and one as a multi-function display. It serves as a replacement for most conventional flight instruments and avionics.
Components
An aircraft with a basic Garmin G1000 installation contains two LCD displays (one acting as the primary flight display and the other as the multi-function display) as well as an integrated communications panel that fits between the two. These displays are designated as a GDU, Garmin Display Unit.
Beyond that, additional features are found on newer and larger G1000 installations, such as in business jets. This includes:
A third display unit, to act as a co-pilot PFD
An alphanumeric keyboard
An integrated flight director/autopilot (without it, the G1000 interfaces with an external autopilot)
Depending on the airplane manufacturer and whether or not a GFC 700 autopilot is installed, the G1000 system will consist of either two GDU 1040 displays (no autopilot), a GDU 1040 PFD/GDU 1043 MFD (GFC 700 autopilot installed), or a GDU 1045 PFD/GDU 1045 MFD (GFC 700 autopilot installed with VNAV).
