Tower Simulation Systems E2 - Challenge Based Acquisition

The Federal Aviation Administration (FAA) has a requirement for air traffic controller training simulator operation and related services under the Tower Simulation System (TSS) program.

The FAA intends to deploy additional TSSs to training sites around the National Airspace Systems (NAS) to improve controllers’ access to high-fidelity simulators and facilitate faster, more efficient controller training and certification. The FAA is also seeking to improve the capabilities of the TSS and the delivery of TSS services through technological innovation. The FAA has designated this effort “TSS E2.”

For TSS E2, the FAA is issuing a Challenge Based Acquisition (ChBA). An overview describing the ChBA process is provided in the “TSS E2 Request for Concept Papers Feb 2026” document.

As part of Phase I of the ChBA, the FAA is issuing a Request for Concept Papers (RCP). The details of the RCP requirements, including the instructions and evaluation approach of the RCP is provided in the “TSS E2 Request for Concept Papers Feb 2026” document. The Statement of Objectives (SOO) referenced in this document are the finalized objectives resulting from the “FAA Tower Simulation E2 – Statement of Objectives” Special Notice that was issued on 1/29/2026. The SOO is posted with this announcement. In addition, responses to questions received on the SOO are provided in the document titled “Responses to SOO Questions”.

3/6/2026 - The FAA is issuing this amendment to provide responses to questions received. Please refer to the document labeled "TSS E2 ChBA Questions and Answers". Also, an updated Statement of Objectives (SOO) document is provided. Refer to "TSS E2 SOO Amendment 1 March 2026". In response to question 3 in the Q&A, SOO objective 14 is changed from "the development of a VDB and training scenarios for every E2 ATCT" to "the development of a VDB and training scenarios for every ATCT". All other content in the SOO remains the same. In addition, an updated Request for Concept Paper document is provided. Please refer to "TSS E2 Request for Concept Paper March 2026" where section 1.3 Attachments is updated to include the "TSS E2 Vehicle and Aircraft List". This vehicle and aircraft list is added to the Box.com site.
