Esterline CMA-9000 - Dme Arc Interception

OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
DME ARC INTERCEPTION
The FMS provides automatic, autopilot-coupled interception of a DME arc at the arc's starting point.
Interception of the arc at an intermediate point on the arc must be accomplished manually, as follows:
1. Disengage LNAV.
2. Perform a Direct to the arc's starting waypoint.
3. Manually fly the intercept.
NOTE: When the arc capture criteria* are met, leg sequencing to arc navigation occurs automatically, indicated
by an automatic waypoint sequence to the waypoint terminating the arc, and rotation of the HSI course
pointer to the arc's tangential course at the aircraft position.
* For manual arc captures, arc capture criteria include a combination of XTK and TKE as well as being
within +/- 90 degrees of the tangent to the starting point of the arc.
NOTE: The display must be set to MAG (refer to Section 3, Angular References For Navigation And Display).
4. Re-engage LNAV.
or:
Autopilot-coupled interception of the arc at an intermediate point on the arc may be accomplished by moving the
arc's starting point along the arc to the desired radial from the DME station as follows:
With the arc's starting waypoint identifier in scratchpad:
1. Key in /, radial of the desired intermediate point on the arc from the DME station e.g. D173J/220.
2. Display the arc's starting waypoint location in the route by pressing [LEGS] and [NEXT] or [PREV] as
required.
