Why it matters
CloudAhoy is the gold standard for post-flight debrief. It is also a separate $99/yr subscription and only does debrief. Marathon Rank 2 ships parity for the debrief workflow inside AeroCopilot — same maneuver detection class, same ACS gate evaluator — and bundles it with the rest of the platform at the same price tier.
Under the hood
- GPS track ingestion (FIT, KML, GPX, in-cockpit live)
Live ingest pairs with Marathon Rank 9 GPS auto-tracking.
- Maneuver detection algorithm
Steep turn, stall recovery, traffic pattern, S-turns over road, ground reference.
- ACS gate evaluator
PTS tolerances applied per maneuver; gate scored Pass / Marginal / Fail.
- Annotation surface for CFI sign-off
CFI flags any gate needing rework; student sees the rework list.
- Syllabus integration
Gate scores feed directly into the lesson-plan progress chart.
Regulatory and safety context
The Airman Certification Standards (ACS) define quantitative gates (e.g., steep turn altitude ±100ft, heading ±10°). A debrief tool must compare the flown track against those gates to be useful for CFI workflow. CloudAhoy pioneered this; AeroCopilot Marathon Rank 2 closes the parity gap.
