The
Flight Schedule Monitor (FSM), developed
for the FAA by Metron Aviation, provides the FAA,
NavCanada, and Collaborative Decision Making (CDM)
participating airlines with the capability to monitor
airport capacity/demand balance, model traffic flow
management initiatives, and evaluate alternative
approaches. FSM is also used by the Air Traffic
Control System Command Center (ATCSCC) to implement
Ground Stop (GS) and Ground Delay Program (GDP)
strategies. Airline Operations Centers use FSM to
assess the proposed GS/GDP, develop strategies to
cope with the restrictions, and monitor GS/GDP initiatives
that are in effect. FSM is used by 90+ FAA facilities
and 40 airlines in the United States and Canada.
FSM is available as freeware to any system operator
(e.g., airlines, general aviation) who signs a Memorandum
of Agreement with the FAA.
FSM provides common situational awareness to FSM users by presenting airport demand and capacity information both graphically and through text.
FSM provides common
situational awareness to FSM users by presenting
airport demand and capacity information both graphically
and through text. FSM contains several rationing
schemes that seek to maintain a balance between
capacity and demand efficiently and equitably. One
example is the Ration by Schedule (RBS) algorithm
that was essential to enabling FAA/airline data
exchange. Another example is the Compression algorithm,
which provides a means of reassigning flights to
arrival slots in a manner that ensures scarce airport
capacity is fully used. The FSM Power Run enables
the rapid examination of multiple strategies measured
by many different metrics.
FSM's simplified airline
substitution process supports an airline's own schedule
management programs, displays with departure fix
data, new algorithms for the treatment of pop-up
flights, and various performance improvements. Additional
deployed enhancements include graphical power-run
display, distance-based GDPs, multi-fix GDPs, and
multiple airport GDPs.
FSM became officially
operational in June 2000 and continues to evolve
with new capabilities and enhancements. Recent enhancements
include AFPs which combine the
power of Ground Delay Programs and Flow Constrained
Areas (FCA) technology to allow for more efficient
and equitable management of airborne traffic in
congested airspace. To execute an AFP, Metron Aviation’s
Flight Schedule Monitor is used to assign controlled
departure times to flights predicted to pass through
FCAs, thus providing a smooth and manageable flow
of traffic in the airspace. AFPs are the latest
step towards an integrated system-wide solution
to TFM.
