Over the last 10 years, Metron
Aviation has played a major role in numerous FAA
environmental and airspace design projects, and
is a recognized leader in the field of aircraft
noise and emissions modeling. In support of FAA
and airport authorities, Metron Aviation has conducted
numerous large-scale, multi-airport analyses of
noise impacts for both low-altitude and high-altitude
airspace changes. Recent projects in which Metron Aviation has
participated include: NY/NJ/PHL Airspace Redesign,
Cleveland/Detroit Airspace Redesign, Midwest Airspace
Plan, Northern Utah Airspace Initiative, Miami Airspace
Redesign, Orlando Airspace Redesign, Chicago Airspace
Terminal Project, Houston Airspace Redesign, Potomac
Consolidated TRACON and St. George Airport. Additionally,
Metron Aviation is currently supporting the community
advocate team for airspace and procedural redesign
at Boston. Through these projects, Metron Aviation
has developed extensive expertise in airspace design,
and airport environmental planning and noise assessment.
Metron Aviation applies software
tools and other models to support multiple Environmental
Assessments and Environmental Impact Statements.
Metron Aviation is FAA’s developer of the
. NIRS is an
integrated modeling and analysis program designed
to assess noise impacts associated with current
and planned aircraft routings over large regions
and airports. NIRS works in conjunction with other
air traffic modeling systems and procedures in order
to render a complete noise analysis of the impacts
associated with aircraft routing. NIRS is currently
the FAA's standard regional noise model, which efficiently
addresses the large scale requirements of modeling
aircraft noise effects over multi-state regions.
Metron Aviation’s is one of the primary tools
used to discover and analyze noise changes created
by redesigns. ADT identifies current air traffic
patterns using historical radar data from which
noise backbones are created. Once the "baseline"
analysis is used to define current noise levels,
ADT manipulates the backbones to model alternative
designs which can then be exported to FAA’s
Integrated Noise Model (INM) or NIRS to identify
noise impact generated from proposed procedure and
airspace changes. ADT is also valuable in validating
the design by examining simulation data in comparison
to actual radar tracks. Providing a consolidated
view of flight track data, whether real, simulated
or drawn within a GIS application, enables the designer
to verify that all data inputs and outputs are consistent.
Metron Aviation’s provides a crucial
component of NASA’s Virtual Airspace Modeling
Simulation (VAMS) environment to assess environmental
compatibility for current and proposed airspace
concepts. NASEIM solves data integration, data consolidation
and data augmentation problems inherent to large-scale
environmental modeling projects. In addition, NASEIM
provides both noise and emission results that can
be viewed side by side to understand the impact
of one versus the other, a capability that enables
NASEIM to determine which concepts may have either
adverse or beneficial impacts on the environment.
Metron Aviation’s
tool has successfully been used to apply route optimization
technology to several airports. Metron Aviation
performed the “Analysis of the Noise Impact
of Aircraft Operations in the Denver Area”
to identify and quantify measures to reduce noise
impacts from current aircraft operations. The study
optimized flight trajectories of aircraft arriving
and departing from Denver area airports to the fullest
extent practicable, either independently and interactively.
FAA was fully involved both in analysis and implementation
of optimized flight trajectories. Metron Aviation
embedded an early version of ROMA in NASA’s
ACNIM (Airport Community Noise Impact Model) in
conjunction with Wyle Laboratories.
Metron Aviation’s was developed
to provide a noise-aware, terminal area decision
support tool for managing arrival and departure
flows. The tool was integrated with NASA’s
Center TRACON Automation System (CTAS) for arrival
and departure to provide per-flight routing advisories.
DNAP effectively factored aircraft noise in the
routing decision process to achieve long-term noise
avoidance goals.
Leveraging extensive experience
from the Joint Planning and Development Office (JPDO)
environmental analysis, Federal Aviation Administration
(FAA) National Airspace Re-design projects, as well
as National Aeronautics and Space Administration
(NASA) environmental modeling and decision-aid projects,
Metron Aviation will develop a software system to
enable balanced noise and emissions reductions by
integrated Air Traffic Management (ATM)/aircraft
systems. The proposed capability, supports
the next-generation capabilities and environmentally
friendly ATM capability sought under Small Business
Innovative Research (SBIR) Subtopic A3.01 –
Next Generation ATM Systems, directly addressing
integrated ATM/aircraft systems that reduce noise
and emissions.
Metron Aviation fuses the principles of science and mathematics
with the latest technology to provide dynamic and innovative solutions.
In addition to Airspace Design and Environmental Analysis, Metron Aviation’s
comprehensive consulting services include modeling, analysis, and software
development for distributed and collaborative planning systems in all
phases of air transportation.
