Developer-first API

Versioned REST endpoints with JSON and GeoJSON responses.

Aviation map view with approach paths and obstacle overlays

Geospatial mapping

Approach paths, terrain interactions, and obstacle overlays.

14 CFR Part 77

Five imaginary surfaces, evaluated on every site

Part 77 defines the airspace around an airport as a set of imaginary surfaces. A structure that exceeds one of them triggers an FAA notification requirement. Every CurvAero analysis computes all five from the airport's own published geometry and reports the penetration depth against each.

Primary Approach Transitional Horizontal Conical
See how the analysis works
Primary
Centred on the runway centreline and extending beyond each end; its width follows the runway’s approach category.
Approach
Rises outward from each end of the primary surface along the extended centreline, at a slope set by the approach type.
Transitional
Slopes upward and outward at 7:1 from the sides of the primary and approach surfaces to the horizontal surface.
Horizontal
A plane 150 ft above the established airport elevation, bounded by arcs swung from the ends of each runway.
Conical
Extends outward and upward from the edge of the horizontal surface at 20:1 for a horizontal distance of 4,000 ft.

From FAA Source Data to Actionable Intelligence

We source directly from FAA datasets — NASR, DOF, and 5010 — and deliver them through a modern REST API with 28-day AIRAC cycle updates.

  1. 1

    Ingest

    FAA NASR, DOF, and 5010 datasets are automatically fetched and validated each AIRAC cycle.

  2. 2

    Normalize

    Raw government data is cleaned, geo-referenced, and structured into standardized schemas.

  3. 3

    Serve

    Access via REST API, GeoJSON exports, or interactive map visualizations with sub-second latency.
