deleted, all future ETA's are calculated as if no loiter
time will be spent in the MFP.
(11) Exiting the MFP. Performing a direct-to
another waypoint, besides the pattern fix, is the only
way to terminate MFP's. This places the pattern fix
waypoint into history.
o. Intercept Operations.
(1) Intercept Calculations. Up to 10 moving
targets may be simultaneously defined.
solutions to these targets may be inserted as either the
active waypoint for immediate (direct-to) execution or
as a future waypoint to implement a future intercept of
a moving target. Figure 3C-100 and Table 3C-70
illustrate how to define moving waypoint parameters
for use in intercept solutions.
The intercept computations determine the true
minimum time to intercept to the moving waypoint.
This is not a homing type solution. If interception is
not possible, the Point of Closest Approach (PCA)
(i.e., the location where the target will be the closest) is
computed and "PCA Intercept" will be annunciated
when the intercept is the active waypoint.
Solutions are regularly
intercepts whether inserted in the flight plan or not. If
an intercept has not been inserted, the computations
are performed as if it were a direct–to intercept from
present position.
(a) Direct Intercept. When an intercept is
the active waypoint, the intercept location is regularly
updated based on the following information.
1. Current own aircraft position and
speed
2. Moving target definition
The intercept point location is adjusted as
required and the inbound course is edited to match the
current Direct–To course into the waypoint.
perform a direct intercept, perform the following steps.
1. Enter the desired parameters on
the Intercept A page.
2. Press the FPLN INSR line select
key.
3. Press the line select key adjacent
to the TO waypoint location. Refer
