Initial Concepts for Dynamic Airspace Configuration

7th AIAA ATIO Conf, 2nd CEIAT Int'l Conf on Innov and Integr in Aero Sciences,17th LTA Systems Tech Conf; followed by 2nd TEOS Forum (2007)

Parimal Kopardekar Karl Bilimoria Banavar Sridhar

Future airspace needs to be flexible, dynamic and adaptable based on traffic demand, equipage, and weather. Initial concepts focus on three core areas: 1) restructuring airspace, 2) adaptable airspace, and 3) generic airspace. The paper presents mid-term and long-term airspace configuration concepts. These concepts were developed based on literature reviews, workshops, subject matter expert discussions, and field trips. The mid-term airspace configuration concept includes high altitude airspace where user-preferred routes will be predominant and low altitude airspace divided into regions for super density and metroplex areas and remaining portion. Subsequently, the long-term airspace configuration may include four primary regions: 1) airspace for automated separation assurance, 2) high altitude airspace, 3) super density and metroplex operations airspace, and 4) structured classic airspace.

National Unmanned Aerial System Standardized Performance Testing and Rating (NUSTAR)

Parimal Kopardekar

The overall objective of the NUSTAR Capability is to offer standardized tests and scenario conditions to assess performance of the UAS. The following are goals of the NU-STAR: 1. Create a prototype standardized tests and scenarios that vehicles can be tested against. 2. Identify key performance parameters of all UAS and their standardized measurement strategy. 3. Develop standardized performance reporting method (e.g., consumer report style) to assist prospective buyers. 4. Identify key performance metrics that could be used by judged towards overall safety of the UAS and operations. 5. If vehicle certification standard is made by a regulatory agency, the performance of individual UAS could be compared against the minimum requirement (e.g., sense and avoid detection time, stopping distance, kinetic energy, etc.).

The Science of Drones

Parimal Kopardekar Eric Mueller

Drone: the public's term for any flying vehicle that doesn't have a pilot onboard. Unmanned aircraft system (UAS): preferred civil term that emphasizes the drone as a system. Unmanned aerial vehicle (UAV): older but common term, especially in academia. Remotely piloted aircraft system (RPAS): the military's most common term for a drone, and probably the most accurate.

Airspace Configuration Concepts for the Next Generation Air Transportation System

Air Traffic Control Quarterly (2008)

Parimal Kopardekar Karl Bilimoria Banavar Sridhar

Future airspace should adapt to changes in traffic demand, equipage, and weather. In order to achieve this capability, future airspace configuration must be flexible, adaptable, and able to accommodate new airspace elements such as highways-in-the-sky and generic sectors. This paper presents mid-term and long-term concepts for airspace configuration. These concepts were developed based on literature reviews, field observations, discussions with subject matter experts, and research workshops. The mid-term airspace configuration concept includes high altitude airspace where user-preferred routes will be predominant and low altitude airspace divided into regions for super density metroplex areas and conventionally structured low altitude airspace. The long-term airspace configuration includes four primary regions: airspace for automated separation assurance, high altitude flexible airspace, super density metroplex operations low-altitude airspace, and structured low-altitude airspace. These preliminary concepts are being matured using simulations and benefits assessments.

Embracing Innovation in Aviation While Respecting Its Safety Tradition

Parimal Kopardekar

Emerging markets for drones and urban air mobility are going to impact the airspace operations environment. Changes to the current system is necessary to enable new innovations without compromising safety. This presentation discusses how a UTM-inspired air traffic management system can address these needs.

Urban Air Mobility (UAM) Working Groups

Parimal Kopardekar

The NASA Aeronautics Research Mission Directorate (ARMD) is bringing together public, private, and academic organizations to collaborate with NASA in Urban Air Mobility (UAM) working groups. The primary purpose of the working groups is to accelerate the development of safe, high-volume UAM flight operations in the existing and anticipated future national airspace system. In coordination with the Grand Challenge series, industry developments and other ARMD efforts, these working groups will contribute to the enablement of UAM markets. Working group activities will seek to align the community on concepts to enable UAM, including communicating industry demonstrations and R&D priorities. The collaborative efforts will facilitate the identification of critical parameters and standards necessary to develop the framework and approach for safety, certification, airspace, aircraft concepts, technologies, and architectures. The realization of the UAM vision will be possible only though the efforts and contributions of multiple stakeholders, each possessing the necessary authority, expertise, and/or resources to fulfill a critical role in UAM's development, approval, and implementation. The applicable participants will become integral to the UAM working groups and will provide a platform for those stakeholders to collaborate and impact the overall ecosystem.

Implications of Ergonomic and User Considerations on Manufacturing Consumer Products

Venkat Allada Parimal Kopardekar Sam Anand Anil Mital

Abstract Most designers do not consider ergonomic guidelines in designing consumer products. Also, very little attention is generally paid to user needs and preferences. It is imperative that consumer products be designed keeping in mind the human capabilities and limitations. Such considerations in the product design process are necessary since the market is becoming competitive and users more picky. The purpose of this paper is to consider the implications of ergonomic design guidelines on consumer product design, its manufacturing, and associated costs. A Linear Programming model is also developed to assist designers in the product design process.

Feasibility of Mixed Equipage Operations in the Same Airspace

Parimal Kopardekar Nancy Smith Katharine Lee Arwa Aweiss Paul U. Lee

This study used a human-in-the-loop simulation to examine the feasibility of mixed equipage operations in an automated separation assurance environment under higher traffic densities. The study involved two aircraft equipage alternatives - with and without data link- and four traffic conditions. In all traffic conditions the unequipped traffic count was increased linearly throughout the scenario from approximately 5 to 20 aircraft. Condition One consisted solely of this unequipped traffic, while the remaining three conditions also included a constant number of equipped aircraft operating within the same airspace: 15 equipped aircraft in condition two, 30 in condition three, and 45 in condition four. If traffic load became excessive during any run, participants were instructed to refuse sector entry to inbound unequipped aircraft until sector load became manageable. Results showed a progressively higher number of unequipped aircraft turned away under the second, third, and fourth scenario conditions. Controller workload also increased progressively. Participants rated the mixed operations concept as acceptable, with some qualifications about procedures and information displays. These results showed that mixed operations might be feasible in the same airspace, if unequipped aircraft count is held to a workable level. This level will decrease with increasing complexity. The results imply that integrated airspace configuration is feasible to a limit. The results also indicate that the conflict detection and resolution automation, equipage, and traffic density are important factors that will need to be considered for airspace configuration.
