Sensis Innovates Aircraft Departure Sequencing Tool

NYSERDA Contract Helps to Improve Efficiency While Reducing Fuel Burn and
Emissions

EAST SYRACUSE, N.Y., Oct. 5 /PRNewswire/ -- Sensis Corporation is developing a
prototype Departure Manager, an airport operations decision support
application, under a million-dollar project co-funded with the New York State
Energy Research and Development Authority (NYSERDA). The Sensis Departure
Manager can provide air traffic controllers and airline ramp managers with a
decision support tool that automates departure sequencing recommendations
while maximizing runway utilization and minimizing aircraft taxi time at
capacity constrained airports.

U.S. airports operate under a "first-come, first-served" departure sequence,
whereby departure clearance is given by the local controller in the order in
which the departure request is made by the pilot, adding extra time between
departures to accommodate safety and airspace constraints. Consequently,
departure queues form at the ends of runways and other points on the airport
surface as aircraft await clearance to depart, causing aircraft to burn more
fuel and emit more greenhouse gases.

The Sensis Departure Manager calculates the preferred pushback time for each
aircraft to form an optimal departure sequence that minimizes excess taxi time
and departure runway aircraft queuing. The Departure Manager will consider
numerous constraints and factors affecting the departure sequence, including
flight departure time, Air Traffic Control traffic management initiatives,
traffic flow constraints, wake vortex spacing rules and current airport
configuration. As a result, the Departure Manager will maximize runway
utilization by using all available runway departure slots while reducing queue
delays and taxi times. By reducing taxi times, the Departure Manager also
enables reductions in fuel burn and emissions which lower airline operational
costs and reduce an airport's environmental footprint. Ultimately, the
Departure Manager will improve traveler satisfaction with more predictable
flight schedules and fewer airport-related delays.

"At capacity-constrained airports, non-optimal departure sequencing can
contribute to long taxi times and departure delays," said Ken Kaminski,
director of advanced development at Sensis Corporation. "The Sensis Departure
Manager will automatically provide air traffic controllers and airline ramp
managers with a near-optimal departure sequence to maximize runway use and
minimize taxi times and emissions. We are targeting a 10 percent improvement
in runway throughput and taxi time reductions of one minute per aircraft with
the Departure Manager."

Francis J. Murray, Jr., NYSERDA President and CEO, noted that "unnecessary
airport departure delays can be very costly to the airlines, wasteful of
energy and harmful to the environment. For instance, according to industry
statistics, in one recent year, the average departure delay was 12 minutes per
flight, resulting in $9 billion in delay and fuel costs to the airlines.
NYSERDA has provided $499,751 of the project's total value of $1,001,702.
NYSERDA believes that the Sensis approach can eventually be applied to
minimize this problem, not only in New York State's major airports, but in
airports worldwide."
