Flight Management Computer

My FMC/CDU is a combination of a 7 inch TFT screen with VGA and HDMI input at resolution 1280 x 720 and the Opencockpits FMC 747 kit.

Actually one would need a 5 inch TFT screen, however these sizes are hard to find with a VGA input. I did not want to use Displays via TV OUT anymore because TV Out is becoming obsolete at most video cards these days. Therefore I moved towards a bigger TFT screen and am using just part of it. The screen quality is perfect.

The 69 keys of the FMC are connected to an Opencockpits USBKeys card. At each key press this card sends an integer code (not a keystroke) to SIOC. In SIOC these codes are used to operate the Level-D 767 FMC key variables provided by lekseecon.

Two outputs at one of my Mastercards are used for the EXEC and MSG leds. The EXEC led is positioned in the hole for BRT and the MSG led fitted nicely at its real position (see how they shine with a Pedestal lights test).

A small modification to [Window06] in the file panel.cfg of the Level-D makes it easier to map the CDU part of the FMC over the TFT screen without seeing the upper row of the FMC keyboard as well.

 [Window06]
 background_color=0,0,0
 size_mm=1280,650
 position=0
 visible=1
 ident=51
 gauge00=LVLD\B767FMC!CDU,180,180,920,450
 //gauge01=LVLD\B767FMC!Keyboard,318,372,40,59

Gauge01 is no longer needed since we communicate digitally with the Level-D via the LevelD-SDK, and not by generating key strokes.

Note: Navigraph provides actual navigational data and SIDs/Stars every Month. Every now and then I buy an update.
