In an initial three-hour dataset, 105 approaches were analyzed, 90 of them by training aircraft, with 72 selected for instructor review and 7 flagged by at least one rule; one Cessna 172S approach triggered both speed and sink-rate warnings. The project's next step is validating and calibrating its rules against expert human judgment, and it cautions that flags do not confirm a genuinely unstable approach given wind effects and ADS-B measurement limits.", "body_md": "What if an unstable aircraft approach could be identified early enough for a flight instructor to intervene?\n\nThat is the problem behind this open source project: AI Early Warning for Unstable Approaches in GA Flight Training.\n\nThe project uses public ADS-B data from the OpenSky Network around Daytona Beach International Airport (KDAB) to analyze general aviation training approaches.\n\nIt currently:\n\nThe initial dataset covered 3 hours of flight activity:\n\n105 approaches analyzed\n\n90 training aircraft approaches\n\n72 approaches selected for instructor review\n\n7 approaches flagged by at least one rule\n\nOne Cessna 172S approach triggered both speed and sink-rate warnings, highlighting how data-driven methods could support instructor review.\n\nImportantly, the project does not claim that every automated flag represents a genuinely unstable approach. Ground speed is affected by wind, ADS-B measurements have limitations, and instructor review is essential.\n\nThat is what makes the project interesting: the next step is validating and calibrating the rules against expert human judgment.\n\nThis is a good example of how open source aviation data can be turned into a practical safety research problem.\n\n🔗 GitHub: [https://github.com/samsuseelan/ga-unstable-approach-warning](https://github.com/samsuseelan/ga-unstable-approach-warning)", "url": "https://wpnews.pro/news/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-to", "canonical_source": "https://dev.to/aremu_feranmifreddiesc/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-flight-instructor-to-3pmc", "published_at": "2026-10-05 21:12:58+00:00", "updated_at": "2026-10-05 21:17:57.401608+00:00", "lang": "en", "topics": ["machine-learning", "ai-safety"], "entities": ["OpenSky Network", "Daytona Beach International Airport", "Cessna 172S", "GitHub"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-to", "markdown": "https://wpnews.pro/news/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-to.md", "text": "https://wpnews.pro/news/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-to.txt", "jsonld": "https://wpnews.pro/news/what-if-an-unstable-aircraft-approach-could-be-identified-early-enough-for-a-to.jsonld"}}
