The capability to detect and predict surface events
improves the planning and post-analysis of traffic
management initiatives by providing an awareness
of the surface that does not currently exist. The
Enhanced Traffic Management System (ETMS) provides
information to FAA and National Airspace System
(NAS) users so that they can make decisions that
lead to the NAS operating in a safe and efficient
manner. ETMS integrates data from a wide variety
of sources, although there is minimal information
about the status of a flight on the airport surface.
Flight records in ETMS contain fields for reporting
flight event times for four surface events: movement
away from the gate (OUT), takeoff from the runway
(OFF), landing on the runway (ON), and movement
into the gate (IN). These fields, collectively known
as OOOI data, are somewhat sparsely populated with
times reported by the air carriers. The quality
of ETMS estimated times could be significantly improved
if more timely, more accurate, and more complete
reporting of these event times was available.

- Integrate surface information
into the traffic flow management domain
- Provide advanced information
of a flight on the ground awaiting departure
- Improve post-analysis
of NAS operations, beneficial advisories
- Improve strategic planning
management

The concept is to develop algorithms for
integration into local ETMS file servers that process
airport data such as ASDE-X, EFSTS, ADS-B, airline
provided gate and event data, etc., to produce information
on actual surface events, predicted surface events
and other airport specific information that is fed
into ETMS/TFMS and displayed on the OIS webpage.
This information is also archived in a data warehouse
(DW) for post operations analysis, and is available
to the users and decision support systems such as
Departure Flow Management (DFM).
The extraction of surface events
from ASDE-X data for display on the OIS webpage
has been implemented at MEM and SDF in 2006. Additional
data sources and airports are planned for implementation
in 2007.
