Title of Page This box provides information on how a page can be accessed in the FMC

GENERAL FMC INFORMATION •

•

•

Slash RULE o When entering data on a line that has more than one value (wind direction/wind speed) the slash is used to seperate entries. It must be used. o Example: To enter both wind speed and direction one would enter" 215/35" for a 35 knot wind and 215 degrees. o Example: To enter the wind speed only, one would enter "/35" o When entering the first item only the slash is not required. The FMC allows a few "hidden" scratchpad operations to add to your convenience. These functions are changing FMC lighting, changing the power state, and viewing the TUTORIALS menu.

PURPOSE AND USE •

This box provides general descriptions on the purpose and or use of the FMC page

•

Changing the Power State o The FMC relies on aircraft power. If you want to change the FMC power setting, type one of the following into the scratchpad... POWER ON POWER OFF o

•

Press the EXECute button

Viewing the TUTORIALS Menu o If you quickly want to view the TUTORIALS menu, type the following into the scratchpad... TUTORIAL o

Press the EXECute button

Changing FMC Lighting o To change the FMC lighting type the following into the scratchpad... DAY NIGHT NIGHT OFF NIGHT LIGHT Press EXECute when ready to set lighting
