AEROTRACK The chart is on the iPad.
The signal is not.
AeroTrack EFB is an electronic flight bag for Part 91 pilots. FAA sectionals and IFR enroute charts live on the device, not in a cache that expires when the bars do — along with every US airport, your flight plan, and your weight and balance.

What it does
Everything you brief on the ground, still there at altitude.
Built as a working cockpit tool first and a product second — every feature below started as something that was missing on an actual flight.
FAA charts, stored offline
VFR sectionals and IFR enroute low and high, mosaicked from the FAA's own georeferenced source rasters and downloaded as regional packs before you go.
Every US airport
19,426 fields from the FAA's NASR subscription, on device in SQLite: runways, frequencies, elevation, magnetic variation, fuel available and pattern altitude.
Live weather
METARs and TAFs from aviationweather.gov, plotted on the map and colored by flight category, with a full plain-language decode on every airport page.
ADS-B traffic
Connects to a Stratux receiver over GDL-90 for ownship position and traffic with relative altitude, vertical trend and alerting — no subscription in the loop.
Flight planning
Multi-leg routes with a navlog, Direct-To from any airport, cross-track error anchored the way a panel GPS anchors its course line, and a vertical profile with terrain and airspace.
Weight and balance
Per-aircraft loading with fuel entered by type, normal and utility envelopes, and a graph that shows where you actually sit against the limits.
Airspace, TFRs and NOTAMs
Nationwide airspace with tap-through detail, temporary flight restrictions pulled live rather than cached, and NOTAMs keyed correctly so none get silently dropped.
A data bar you configure
Twenty-eight selectable fields across the bottom of the map — groundspeed, track, climb gradient in ft/NM, pressure altitude, ETE. Tap any cell to change it; it stays changed.
Offline is the feature
The aircraft is exactly where connectivity fails.
Plenty of apps will show you a chart while you have a signal and a spinner while you do not. AeroTrack treats that as the failure it is. Charts are cut into regional packs and downloaded on the ground; the airport database ships inside the app; your routes and aircraft live on the device.
- Regional chart packs — take the areas you fly, skip the rest.
- Airports built in — nothing to download before the first flight.
- Cycle dates on everything — you can always tell what is current.
- Live data degrades honestly — stale is labelled stale, not shown as fresh.

Where the data comes from
Public sources, named.
Aeronautical data is only as good as its provenance. Ours is US government public record, and the app shows you the effective cycle of each dataset it is drawing from.

Not for navigation
AeroTrack EFB is a situational awareness aid. It is not a certified navigation system, it is not TSO'd, and it is not approved as a primary means of navigation under any operating rule. The pilot in command remains responsible for verifying all information against current official sources and for the safe conduct of the flight.
Carry what the regulations require you to carry. Treat everything on the screen as advisory.
Beta
Fly it before it ships.
AeroTrack EFB is in private beta ahead of a TestFlight release. If you fly Part 91 and want an early build — especially if you fly with a Stratux — say hello.
