Design the Future of UC Air Mobility:
Vertiport Design for Safe and Efficient Connectivity
The 2025–26 CITRIS Aviation Prize aims to advance air mobility by bringing University of California students, researchers and professionals together to design critical aviation simulations and subsystems, integrating air transit into campus transportation networks and empowering efficient intercampus travel.
This competition is open to undergraduate and graduate students enrolled at the UC campuses in Berkeley, Davis, Merced and Santa Cruz.
Overview
The first CITRIS Aviation Prize, launched in 2021, challenged student teams to develop a long-distance, fully autonomous flight with a small UAV, culminating in a successful demonstration. Building on this achievement, the 2023–24 competition envisioned a forward-looking air mobility system for the university, incorporating advanced air mobility (AAM) technology to revolutionize transportation within and among campuses.
The 2024–25 competition continued an exciting multiyear journey to advance campus air mobility by tasking student teams to develop air operations system simulation software for the proposed University of California air mobility system, paving the way for efficient campus-to-campus travel across the UC system.
This year, the 2025–26 CITRIS Aviation Prize builds on these efforts by focusing on the operational framework for an advanced intercampus air transportation system — the California Airlink — that will connect the four CITRIS campuses and Moffett Field via electric vertical takeoff and landing (eVTOL) aircraft.
Representatives from NASA’s Ames Research Center will participate in our judging panel, bringing unparalleled expertise in aerospace technology and innovation to evaluate the student proposals. The competition will conclude with final team reports and an awards ceremony, providing students the opportunity to present their innovative air mobility solutions directly to leading experts in the field.
Subsequent CITRIS Aviation Prize competitions will further develop these AAM plans, with future challenges delving into campus infrastructure design and ultimately culminating in real-world testing and implementation. This phased approach ensures a comprehensive and sustainable advancement of air mobility technologies.
Objective
The goal of this year’s competition is to develop a scalable California Airlink operations concept consisting of a simulation framework that validates designs of vertiport location, layout and operations. The proposal should assess risky segments of the vertiport operation, such as takeoff and landing, with an emphasis on uncertain and unfavorable weather conditions and emergencies.
Specifically, the teams are asked to:
- Design vertiport placement simulation tool for the entire Airlink along with low-altitude vehicle routes for takeoff and landing in normal and emergency situations, taking care to address potential system failure and extreme weather. Specify any sense-and-avoid and weather prediction capabilities required. Evaluate how proposed vertiport placement enables safe and efficient connectivity across key Northern California locations.
- Create a roadmap for vertiport deployment and flight testing and assess economic scaling, linking simulation-based validation to real-world demonstration while analyzing costs of vertiport deployment and expansion of our intercampus Airlink.
The emphasis of the project is on developing simulation tools that enable safety, scalability and cost-effectiveness analyses, while providing a pathway toward real-world demonstration and implementation in the near future.
Competition Structure
There will be two phases in the competition.
Phase 1: Design Proposal (due Nov. 20)
- Interested teams from each campus, including teams with members from multiple campuses, submit proposals outlining their vision toward the competition’s objective.
- A panel of expert judges reviews the proposals and recommends a number of teams to move on to Phase 2.
Phase 2: Detailed Design and Presentation (December through May)
- Selected teams develop detailed designs incorporating feedback from Phase 1.
- Teams meet monthly with CITRIS Aviation for design updates.
- Teams provide a design showcase midway through the process.
- Teams offer their final design presentations for judging.
Eligibility
The competition is open to student teams from the four University of California campuses affiliated with CITRIS and the Banatao Institute: UC Berkeley, UC Davis, UC Merced and UC Santa Cruz.
Teams are required to include:
- Two to a maximum of eight students
- At least one undergraduate student and no more than three graduate students
- One postdoctoral fellow or faculty mentor as an adviser
Registration
Teams register and submit their Phase 1 proposals through an online application form. This form requires teams to enter contact information for all members and to provide a shareable link to their proposal as a PDF.
Proposal Guidelines
- Proposals must be submitted as a PDF using a minimum 10-point font size with 1-inch margins. Phase 1 proposals are limited to three pages, and Phase 2 proposals are limited to 10 pages.
- Additional pages may be used for title page, references, and figures or renderings as long as the body of the proposal does not exceed the specified page limits. Additional pages may include one-sentence descriptions of the renderings, but should not be used to include additional proposal narrative material.
- You will be required to submit an approval form signed by your adviser, which you can download from the submission portal.
Phase 1 Proposals (Nov. 20, 2025)
Proposals should outline the team’s vision for a scalable Airlink operations concept, emphasizing simulation frameworks for vertiport placement, approach and takeoff route designs, weather-aware and emergency operations, and economic scalability.
Be sure to include the following elements:
- Simulation software to validate vertiport location, layout and operations.
- Vertiport placement strategy for the Airlink network, including integration with low-altitude vehicle routes for normal and emergency situations (e.g., system failures, extreme or uncertain weather). The strategy should enable Airlink service between the following locations across the proposed operational region:
- UC Berkeley
- UC Davis
- UC Merced
- UC Santa Cruz
- Moffett Federal Airfield (KNUQ)
- Marina Municipal Airport (KOAR)
- Salinas Municipal Airport (KSNS)
- Hollister Municipal Airport (KCVH)
- San Carlos Airport (KSQL)
- Livermore Municipal Airport (KLVK)
- Initial requirements for sense-and-avoid capabilities and weather-prediction systems to support safe takeoff, landing and en route operations.
- Preliminary economic assessment of vertiport deployment and scaling across Northern California, including installation, maintenance and management costs; target revenue and usage; and upfront investment and amortization schedule.

Phase 2 Proposals
Proposals selected for Phase 2 should include the following elements:
- Detailed description of required features outlined in Phase 1, refined and validated through initial simulation results.
- Comprehensive details on the simulation framework, including architecture, functionality and integration with vertiport placement and routing strategies.
- In-depth description of operational safety systems, including technical specifications for sense-and-avoid, weather prediction and emergency rerouting protocols.
- Roadmap for staged flight testing and economic scaling, including:
- Identification of key stakeholders, regulatory considerations, environmental impacts, funding strategies and phased timelines.
- Estimated costs and implementation timelines for vertiport deployment and Airlink expansion.
- Strategies for incorporating feedback from potential users (e.g., routes, schedules), operators and stakeholders to refine and optimize the proposed systems.
