(W, A)  should be path and speed stable on approach. Gates are placed on the 3 Degree Reference Line or FMC Approach Glidepath Angle Line: . at 1000 feet above field elevation(W). . at 500 feet above field elevation(A). Decision gates that are below the missed approach waypoint altitude will not be displayed. 

 Flight path vector (W)  Fixed length line indicates current flight path angle and rotates about the point of the triangle. Angle of the line is dependent on the vertical speed and ground speed of the airplane. 
MCP selected  Dashed line indicates the selected vertical speed 

 vertical speed  as a target angle when the MCP V/S mode is 

 vector (M)  selected. Extends to the edge of the background display and rotates about the point of the triangle.

SYMBOL  NAME  REMARKS 

 Range to target speed dot (G)  Indicates where the airplane will achieve the FMC or MCP target speed. If the airplane is within 5 knots of the target speed the dot will be blanked. If the airplane increases 10 knots or more faster than the target speed the dot will reappear. Displayed at the end of the Flight Path Vector as an unfilled dot if the target speed will not be achieved within the vector length.
