The 'External Primary Flight Display' is simulation of the Boeing 747-400 PFD. Using data from the PS1.3 Broker, 747IPC and VMread, the PFD of PS1.3 is redrawn on a second networked computer using OpenGL. The goal is to create a larger PFD.

Possible applications are the PS1.3 home cockpit or the serious IFR pilot who uses the external PFD for more accurate flying due to the larger size of the external PFD. In the home cockpit, captain's and F/O's displays can be set up. Future versions will support source selection and display switching, and the capability of display the PFD on the ND screen and vice versa.

While at present only the major functions (FMA, ILS, Flight Director) of the PFD are supported, this project intends to cover all display modes of the PFD in future versions.
