Frequently Asked Questions
What charts does ChartBrief cover?
ChartBrief covers the FAA Digital Terminal Procedures Publication (d-TPP): instrument approach procedures (ILS, RNAV, VOR, LOC, NDB, etc.), Standard Instrument Departures (SIDs), Standard Terminal Arrivals (STARs), airport diagrams, takeoff minimums and departure procedures, hot spots, and LAHSO. Coverage updates every FAA 28-day cycle. VFR sectionals, IFR low/high en-route charts, and the Chart Supplement are not in d-TPP and are not covered by ChartBrief in v1.
How current are the charts and NOTAMs?
Charts are pulled directly from the FAA d-TPP archive each 28-day cycle and the app shows the cycle effective date in the chart picker. NOTAMs are pulled from the FAA NOTAM API and cached server-side with a 1-hour TTL. The staleness indicator on every NOTAM panel tells you how old the cache is, e.g. "NOTAMs as of 12 minutes ago." Always re-verify against the official FAA NOTAM source before flight.
How is the AI briefing generated?
When you tap "Brief This Chart," ChartBrief sends the chart's structured data, the current NOTAMs at the airport, and your selected aircraft profile to AIVIATION servers (AWS, us-east-2). ChartBrief's AI generates the annotation overlay and briefing summary on AIVIATION's servers from that data, then returns it to your device. AI-generated content may contain errors -- always cross-check with the official chart and NOTAMs.
What is the difference between Free and the subscription?
Free. Chart viewing (clean plates, no watermark), raw NOTAM list (unfiltered, unprioritized), 3 free flights (plan a flight and every chart in it is briefable, no per-flight chart cap), and unlimited aircraft profiles. No subscription required and no account needed.
Subscription — $4.99/month or $39.99/year. Quick Brief on any airport (a one-tap AI briefing of any single chart without planning a flight), unlimited AI briefings, NOTAM-to-chart correlation in briefings, and saved briefings for offline review. 7-day free trial on the annual plan. Cancel anytime.
Why is the free tier limited to 3 flights?
Each AI briefing has a real per-call cost. Three free flights -- every chart in each flight included -- is enough to fly the full plan-brief-fly loop on trips you actually care about, then make a buying decision. Raw chart viewing and NOTAM access remain unlimited on the free tier so safety-critical access is never gated. Quick Brief -- a one-tap AI briefing of a single chart without planning a flight, available from the Charts tab -- is part of the subscription.
How does offline use work?
Once you've briefed a flight while online, the chart PDFs, annotations, checklist, and NOTAM snapshot are cached on your device, so the in-flight checklist works with no signal. There is no on-device AI -- to generate or re-brief a chart you need a connection.
Can I rely on ChartBrief for actual flight operations?
No. ChartBrief is a briefing and training aid. It is not a primary or authoritative navigation source. Always fly from the current official FAA chart and verify NOTAMs against the FAA's authoritative source. AI-generated annotations and briefing summaries may contain errors.
