multi-function display (MFD). For the GDU 620 RH, the right side of the GDU is the
primary flight display (PFD) and the left side is the multi-function display (MFD). The
PFD shows primary flight information. The MFD shows navigation and flight plan in-
formation, traffic, weather and terrain. An external configuration module is used, so no
