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. 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

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

These pages selectively display data using a common format for each of the four standard descent modes: Path descent-Best
ECONomy or any manually selected descent speed, and Speed descent-Best ECONomy or any manually selected descent speed. Speed descents are altitude and airspeed constrained but require vertical path control using thrust levers and speedbrakes. If the MCP has already been set to a lower altitude, the V NAV speed descents are automatically initiated at the computed top-of-descent. FMC predictions assume a computed profile to 1000 feet above the destination field elevations at a position which will vary according to selection of arrival procedures. A slowdown profile for approach will be provided by the FMC. L NAV does not need to be engaged to fly a VNAV SPEED DESCENT.
The active controlling speed is highlighted by reverse video characters (on lines 2L or 3L). Path descents are altitude constrained and require manual speed control. If a lower MCP altitude has been selected, then V NAV descent is automatically initiated at T/D. The computed profile terminates at the end-of-descent (E/D) altitude/waypoint. Only if a mandatory "at" altitude restriction is specified at E/D can a path be computed.
