Figure 3C-101. Direct Intercept Insertion
Table 3C-71. Direct Intercept Insertion
When the intercept has been defined,
pressing FPLN INSR line select key will
access the flight plan.
Inserts the intercept before this point in
the flight plan (in this case, a direct
intercept is being performed).
An I indicates that an intercept has been
attached to this waypoint.
Intercept position is displayed as a LAT
LONG and is updated every 22 seconds.
(b) Planned Intercepts. When the
intercept is inserted as a future waypoint, the intercept
location is regularly updated based on the following
1. Location of the flight plan waypoint
immediately prior to the intercept.
2. Distance along the flight plan from
aircraft position to the waypoint
prior to the intercept.
3. Current own aircraft speed.
4. Moving target definition.
5. Current wind.
The estimated time of arrival at the waypoint
immediately prior to the intercept is computed. The
intercept point and its ETA are computed from that
point in exactly the same manner as the direct case.
The intercept is executed exactly as the direct
intercept when it becomes active. Refer to
Figures 3C-102 and 3C-103.
(2) Intercept Passage. When an intercept is
passed into history, the latitudelongitude of the
intercept at the time of waypoint passage is recorded
as the flight plan history waypoint and the I is removed
from the waypoint.
(3) Multiple Intercepts. Ten moving waypoint
(intercept) definitions may be inserted in the flight plan.
Each intercept solution is computed independently and
flown in the flight plan sequence.
(4) A calculator function is provided to allow
the crew to enter an alternate TAS and see the effect
on the intercept. This calculator is available for an
intercept not inserted into the flight plan and for the
Figure 3C-104 and Table 3C-72.
p. Markpoint and Waypoint List Storage.
(1) Markpoint and Waypoint List Overview.
The FMS800 maintains a markpoint list of up to 10
markpoints and a user waypoint list of up to 200
waypoints. The lists are stored in nonvolatile memory.
Each list is maintained on separate pages and is
accessed from the Flight Plan Edit page. Refer to
Figure 3C105 and Table 3C-73. To access the
Markpoint List page, press the MARKPT line select
key on the Flight Plan Edit page. To access the
Waypoint List page, press the USER WYPT line select
