Each cor_tr'oller was given a headset, microphone_ and radio frequency
seler.:tor.
The simulation was based on a southern approach to runway ._(.)L at
C_
._an Jose Airport. The. lo(zation and names of some of the waypoints
wer-e modified to create three converging routes with r-eporting
points located at equal distances from the airport along t.he
routes. Aircraft entered the simulation at one'of seven _aypoints
located 65_ 46, or 35 km. from the airport. The descent from
the LICKE intersection to the airport (DME 16) was based on a
standard approach plate for runway 30L. ]"he localizer and glideslope
were interr:epted at LICKE for a simulated instrument landing
system (ILS) apprc:)ach.
Appropriate initial altitudes and starting speeds were programmed
for the three aircraft types and the different starting locations.
Entry into the system was scheduled to simulate routine handoffs
from an enroute control facility. Longitudinal separation of at
least 9 km For- airc:raft at the same altitude or a vertical separa-
• t-j- -
tion of at least I=L)()m for aircraft at the same position was
provided as an initial condition. The end of each run c_ccurred
when the last aircraft landed.
Twenty different scenarios were developed that represented four
levels of VFR aircraft intrusion. Four were used for practice
