<strong>Trajectory</strong>-<strong>Based</strong> <strong>Operations</strong> (<strong>TBO</strong>)<br />
Study Team Report<br />
This RNP approach has crossing speed restrictions at the HODLE <strong>and</strong> DOXSI fixes.<br />
Before reaching the Taylor TAY Arrival Meter Point, Ariba 151 receives a runway assignment to<br />
RWY 12 <strong>and</strong> is assigned the SSCOT ONE ARRIVAL (RNAV) STAR <strong>and</strong> RNAV (RNP) X RWY 12<br />
Approach. Ariba 151 arrives at the<br />
TAY Arrival Meter Point to MIA<br />
from the north <strong>and</strong> enters the<br />
SSCOT ONE STAR. Because<br />
Ariba 151 is NextGen Classicequipped,<br />
with minimal onboard<br />
capability, the ANSP uses groundbased<br />
automation to issue speedbased<br />
clearances to manage it. The<br />
ANSP automation has assigned<br />
Ariba 151 a CTA to a fix at the<br />
RWY 12 threshold, <strong>and</strong> has<br />
generated a 4DT to the CTA. The<br />
ANSP is managing Ariba 151 in a<br />
time-based manner with respect to<br />
other traffic, but the Ariba flight<br />
crew only deals with following the<br />
assigned 3D route at the assigned<br />
speed. The ANSP must retain larger<br />
RTP buffers around the CTA<br />
timing because of Ariba’s reduced<br />
timing accuracy.<br />
Winds Air 134 is approaching the<br />
southwest Key West EYW Arrival<br />
Meter Point, <strong>and</strong> receives the<br />
following assignments: CURSO<br />
TWO ARRIVAL (RNAV) STAR<br />
to RNAV (RNP) X RWY 9<br />
Approach, airborne merging <strong>and</strong><br />
spacing behind Northeast 416, with<br />
2.4-minute separation at runway<br />
Figure 7. Current CURSO TWO ARRIVAL (RNAV)<br />
threshold. Using ADS-B, state<br />
information to determine Northeast 416’s current position <strong>and</strong> speed, together with additional ADS-B<br />
intent information such as Northeast 416’s planned FAS. The Winds Air 134 conflict detection <strong>and</strong><br />
resolution capability projects when Northeast 416 will cross the DOXSI final approach fix <strong>and</strong> the<br />
runway threshold, <strong>and</strong> the FMS generates an OPD 4DT to arrive with the proper spacing behind<br />
Northeast 416. Northeast 416 is arriving via a different STAR <strong>and</strong> entering the RNAV (RNP) X RWY<br />
9 Approach from a different waypoint, but Winds Air 134 was data linked Northeast’s arrival <strong>and</strong><br />
approach routes, so it can accurately calculate Northeast’s path <strong>and</strong> time to the runway threshold.<br />
