Esterline CMA-9000 - Introduction; Navigation of Direct-To a Waypoint When Fms Is Configured for a Standard Direct-To

OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
SECTION 9
DIRECT-TO/INTERCEPT
INTRODUCTION
The active flight plan may be modified at any time by the entry of a direct-to procedure to navigate the aircraft
directly to a downtrack waypoint or to intercept a course inbound to a waypoint. The direct-to waypoint may be
an existing waypoint on or off the route. Entry of an off-route waypoint will create a discontinuity in the active
route which can be closed up as described in Section 5. When the direct-to waypoint is already part of the
current flight plan, all flight plan waypoints prior to the direct-to waypoint will be deleted.
The following describes the Direct-To a fixed course/Direct-To a heading and the Direct-To a waypoint
procedures.
NAVIGATION OF DIRECT-TO A WAYPOINT WHEN FMS IS CONFIGURED FOR A “STANDARD”
DIRECT-TO
When a Direct-to a waypoint procedure is executed the FMS calculates an intercept course to the waypoint based
on the aircraft velocity, present position, track, and wind velocity.
Roll steering command, track angle error (TKE), and lateral deviation (XTK) are provided to guide the aircraft to
intercept the calculated course.
Figure 9-1 illustrates the Direct-To a waypoint procedure.
