A Tour of vCFI: The Free AI Flight Instructor I Built for Student Pilots
Full disclosure up front: I built vCFI. It's part of my Subsonic Pilot project. This post is a walkthrough of what the app does and why it exists, not an arms-length review. The goal is to show you the tool, not sell you anything — it's free, there's nothing to upgrade to, and you can be using it in 10 seconds.
vCFI is a web-based AI flight instructor purpose-built for student pilots. It opens immediately at vcfi.subsonicpilot.com with no login, no signup, and no paywall. Five modules under the hood: Flight Chat with FAA-aligned responses, a Flight Planner with a built-in W&B calculator, a Post-Flight Debrief that walks scenarios with FAR citations, a Lesson Planner keyed to the ACS, and an ATC Radio Simulator with realistic controller phraseology.
I built it because general LLMs kept hallucinating FAR citations and AIM sections that don't exist. The structure underneath enforces FAA terminology, mnemonics like PARE, and real CFR references — so the responses feel like a briefing from a patient instructor instead of wandering prose. Inside the post: 7 captured screenshots, the design decisions behind each module, and an honest look at the rough edges (no account/persistence, no syllabus, no live weather).
