Tower Simulation System Enhancement 2 Challenge-Based Acquisition

Request for Concept Paper

Version 1.0 February 24, 2026 Contents

TSS RCP E2 i Introduction Background The Federal Aviation Administration (FAA) operates a complex air traffic control system that relies on highly trained controllers to manage aircraft movements safely and efficiently. The FAA uses high-fidelity air traffic control simulators, called Tower Simulation Systems (TSSs), to train and evaluate controllers in performing air traffic control operations. TSSs enable the FAA to design training scenarios to meet the FAA’s training objectives and allow controllers to practice air traffic control procedures in a highly realistic virtual environment without risk to National Airspace System (NAS) operations. The FAA currently operates 111 TSSs to meet the training needs of controllers stationed at all 264 FAA-operated air traffic control towers (ATCTs) throughout the NAS.

The FAA has an urgent need to expand the controller workforce to address current and anticipated staffing shortages. TSSs, which can accelerate controller training and reduce the time required for certification, will play an important role in helping the FAA achieve its controller staffing goals. However, there are 173 ATCTs in the NAS that do not have a TSS on site. Controllers at these ATCTs must travel to other facilities for simulation training, incurring costs and requiring time for travel that exacerbates existing controller staffing shortages.

The FAA recognizes the need for additional TSSs. Furthermore, the FAA Reauthorization Act of 2024 mandated that the FAA improve controllers’ access to high-fidelity simulators by May 2028. Under the TSS E2 acquisition, the FAA is seeking an enhanced TSS solution that will be deployed to 102 training sites by May 2028 and TSS operation and maintenance services through the end of the period of performance.

In May 2025, the FAA announced the Brand-New Air Traffic Control System (BNATCS) plan, a comprehensive effort to transform the United States’ air traffic control system. To lead and manage the BNATCS effort across the FAA, the FAA awarded a prime integrator contract to Peraton.

Due to the TSS’s importance to achieving the FAA’s controller staffing goals, the FAA has designated the TSS program as part of the BNATCS portfolio.

Purpose The FAA is issuing this Request for Concept Paper (RCP) to initiate the TSS Enhancement 2 (E2) Challenge-Based Acquisition (ChBA). Under the ChBA framework, the FAA or its designated agent may conduct a multi-phase evaluation process involving challenges, which could include demonstrations, prototypes, presentations, and proposals, culminating in the selection of a complete TSS E2 solution. The purpose of this RCP is to identify the offerors eligible to participate in these future phases. In later phases, the FAA or its designated agent may award one or more contracts or subcontracts to procure the hardware, software, and services necessary to implement the selected solution. If a viable solution is developed, the FAA or its designated agent may proceed with one or more contracts or subcontracts to implement that solution.

This RCP is not a Screening Information Request (SIR) or Request for Offers (RFO). The responses to this announcement will not be construed as a commitment or a promise to contract with the FAA. The FAA is not seeking or accepting unsolicited proposals. Any costs associated with the response to this announcement are solely at the interested respondent’s expense. Material will not be returned.

TSS E2 Challenge-Based Acquisition Overview The purpose of this section is to provide an overview of the phases of the TSS E2 ChBA.

· Phase I – Concept Paper: The FAA issues the RCP. Responses may be provided to the FAA or its designated agent. Upon review of the responses, the FAA or its designated agent will invite offerors to participate in future phases.

· Phase II – Proof of Concept: The FAA or its designated agent will provide offerors with up to 60 days to prepare a proof of concept against scripts and use cases. This will culminate in a proof-of-concept demonstration and a FAA- or FAA-designated-agent-facilitated question and answer period. The offerors that best address the scripts, use cases provided, and the associated evaluation criteria will be invited to future phases, if required, or to enter into a subcontract agreement.

Instructions to Offerors Minimum Acceptability The FAA requests that offerors’ submissions conform to the following requirements:

Contain a one-page cover sheet with the following information: Company name; Name of proposed TSS solution; Date of submittal; and Primary point of contact, including name, company, title, address, telephone number, and email address Comply with the formatting requirements in section 3.2 Be submitted according to the instructions in section 3.4 Formatting Concept papers must adhere to the following formatting requirements:

The font must be Times New Roman 12 point (or larger) single-spaced. Smaller fonts may be used for figures and tables but must be clearly legible.

Pages must be single-sided, 8.5 by 11 inches, with at least 1-inch margins on all sides (top, bottom, left, and right).

Page limit is twenty-five (25) total pages excluding the cover sheet, table of contents, and the ROM Estimate. Page limitations must not be circumvented by including inserted text boxes, pop-ups or internet links to additional information. Such inclusions are not acceptable and will not be considered as part of the response to this RCP.

Concept Paper As part of Phase I of the Challenge-Based Acquisition, offerors are asked to describe how they would meet the objectives in the TSS SOO. Offerors are asked to describe how they would specifically address the operational concept, technical, implementation and deployment, and operations and maintenance model for delivering a TSS solution. Offerors must include the following sections in their response:

Technical Approach and Solution Architecture Implementation Approach Operational Approach ROM Estimate Technical Approach and Solution Architecture Offerors must describe their proposed solution and how it meets objectives 1-7 of the SOO. Offerors must identify the components of their solution and describe their level of maturity with respect to meeting the objectives. Offerors must identify relevant risks and their proposed approach for managing them.

Implementation Approach Offerors must describe their approach and timeline to delivering a complete solution by May 2028 to meet objective 14 of the SOO. Offerors must describe their approach to acquiring and deploying the software, hardware, personnel, and facilities used to produce, deliver, operate, and maintain the solution. Offerors must identify relevant risks and their proposed approach for managing them.

Operational Approach Offerors must describe their approach to meeting objectives 8-13 of the SOO. Offerors must describe the roles of team members, facilities, and support resources. Offerors must identify relevant risks and their proposed approach for managing them.

ROM Estimate Offerors must provide a rough order of magnitude (ROM) estimate of the total cost of their proposed TSS E2 solution in an offeror-developed format that includes the cost to develop and deploy TSSs to 102 designated sites covering the full deployment period through May 2028 and for one (1) additional year of operational and maintenance services. The ROM estimate must address each of the cost elements separately.

Offerors must provide a narrative describing their basis of estimate (BOE) which contains clear traceability between each BOE and each cost element. The BOE supporting data must explain what is included in the price of each element and provide traceability between the priced services and the technical approach, business model, and implementation plan. The BOE for each cost element must contain sufficient detail to allow the evaluators to assess the cost and price realism, balance risk, completeness, consistency, and traceability, as needed. Offerors must clearly identify and explain any cost elements that have interdependencies with other cost elements.

Submission Instructions An offeror that includes in its concept paper data that it does not want to be disclosed to the public for any purpose or used by the FAA except for consideration and selection purposes must mark the information “Proprietary.”

Responses are due by 2:00PM Eastern Time on Tuesday, March 24, 2026. Responses should be emailed to the Contracting Officer, Manish Patel, at manish.patel@faa.gov. The email subject must be “ChBA TSS Request for Concept Paper.” The FAA intends to send a confirmation email within 24 hours of receipt; an offeror not receiving a confirmation email should follow up with the Contracting Officer to confirm receipt.

Offerors may submit questions regarding this RCP to the Contracting Officer at manish.patel@faa.gov until 2:00PM Eastern Time on Tuesday, March 3, 2026.

The cover sheet and concept paper must be separate Adobe .pdf files named “RFP_CovSheet_[Offeror Name].pdf” and “RFP_Concept_[Offeror Name].pdf”. The cover sheet file must be formatted to letter-size paper with one-inch margins. Color is permissible, but each document should be readable if printed in black-and-white. All files must be submitted in the same email transmittal.

The Cover Sheet.pdf file and the Concept Paper.pdf file should contain only the number of pages allowed in the instructions above. Documents that exceed the page limitations will only be reviewed through the stated page limitation, which will result in the offeror’s full concept not being evaluated fully and eliminating progression to the next phase. The email transmittal may include additional text (such as whom to contact if the files are corrupted), but those emails will not be read by the peer review panel.

An offeror may submit multiple concept papers covering the FAA’s objective for this announcement. Each should be a separate email submittal following all instructions above. Multiple concepts should be submitted only where the concepts differ greatly in innovation or process. The FAA desires unique and innovative concepts. If multiple offerors submit very similar concept papers, the FAA or its designated agent may select any one or more of those for future phases of this challenge.

Evaluation Approach The goal of the TSS E2 source selection process is to select the proposed solution that meets the FAA’s requirements and offers the best value to the FAA. The goal of the TSS E2 Phase I evaluation of concept papers is to identify offerors that may be invited to participate in future phases of the TSS E2 ChBA. Offerors will be eliminated from further participation in the TSS E2 ChBA if the FAA or its designated agent determines during the Phase I evaluation that it is unlikely that the offeror’s proposed solution would offer the best value to the FAA.

The FAA or its designated agent will evaluate responses by assessing the degree to which the response presents a complete and realistic solution that addresses all the objectives in the SOO and the requirements in this RCP and by assessing the totality of the strengths, weaknesses, and risks identified in the response. The definitions of strength, weakness, and risk are listed in Table 1.
