Approach with DME arc segments
Approach procedures which utilize a DME arc transition may be flown using the
GNC300.
For course guidance along the DME ARC, the pilot must select the NAV
Position Page on the GNC300 and assure that the reference waypoint displayed
is the approved reference facility for the DME ARC. The distance to the
reference facility is depicted on the right of the screen and may be used in the
same way that a DME presentation would be used to fly the arc.
Once established on the DME ARC, the pilot must select HOLD mode using the
GPS SEQ switch. (Ensure HOLD is accomplished on the intermediate fix
located at the intersection of the arc and the course which completes the arc.)
Set the HSI to the published intermediate or final approach course. The HSI
will then display course deviation relative to that course. When the intermediate
or final approach course has been intercepted, the pilot must select AUTO mode
using the GPS SEQ switch.
Note: AUTO mode must be selected at least 2 nm prior to
the next waypoint.
If an autopilot/flight director is used, the pilot must select HDG mode on the
autopilot/flight director and manually adjust heading as necessary to maintain
the required path along the DME ARC. Once the final approach course has
been intercepted, NAV or APPR mode may be selected on the autopilot/flight
director if desired.
Holding at a fix
The GNC300 may be used to hold at any waypoint by simply selecting that
waypoint and placing the GPS SEQ switch in the HOLD mode. The HSI course
pointer may then be used to select the holding or non-holding course as
appropriate.
