@squawk/fix-data

  @squawk/fix-data

Pre-processed snapshot of US fix/waypoint data derived from the FAA NASR 28-day subscription cycle. Data only - no query logic, no dependency on @squawk/fixes.

Documentation

Part of the @squawk aviation library suite. See all packages on npm.

Coverage

• All non-CNF US named fixes and waypoints: waypoints, reporting points, VFR waypoints, NRS waypoints, military waypoints/reporting points, and radar fixes
• Geographic coordinates (decimal degrees)
• Usage category (WP, RP, VFR, NRS, MW, MR, RADAR)
• ARTCC assignment (low and high altitude)
• Compulsory reporting designation
• Operational flags (pitch, catch, SUA/ATCAA)
• Minimum reception altitude where published
• Chart type associations (IAP, STAR, SID, ENROUTE, etc.)
• Navaid associations with bearing and distance

Installation

npm install @squawk/fix-data

Usage

import { usBundledFixes } from '@squawk/fix-data';

// Inspect metadata
console.log(usBundledFixes.properties.nasrCycleDate); // "2026-01-22"
console.log(usBundledFixes.properties.recordCount);

// Use with @squawk/fixes for zero-config fix queries
import { createFixResolver } from '@squawk/fixes';

const resolver = createFixResolver({ data: usBundledFixes.records });

Consumers who have their own data pipeline can use @squawk/fixes alone and pass any compatible Fix array at initialization.

Data format

Each record is a full Fix object from @squawk/types. Key fields:

lat, lon	number	Decimal degrees
state, country	string	Two-letter codes
useCode	FixUseCode	WP, RP, VFR, NRS, MW, MR, or RADAR
highArtccId	string or undefined	High-altitude ARTCC (e.g. "ZNY")
lowArtccId	string or undefined	Low-altitude ARTCC
compulsory	FixCompulsory or undefined	HIGH, LOW, or LOW/HIGH
pitch	boolean	Pitch designation
catch	boolean	Catch designation
suaAtcaa	boolean	Special Use Airspace / ATCAA association
minimumReceptionAltitudeFt	number or undefined	MRA in feet
chartTypes	string[]	Charts the fix appears on (IAP, STAR, ENROUTE, etc.)
navaidAssociations	FixNavaidAssociation[]	Bearing/distance from nearby navaids

Data source

The bundled snapshot is built from the 2026-04-16 NASR cycle. The FAA publishes updated NASR data every 28 days. To update, re-run the build pipeline below against a newer cycle.

All data is derived from the FAA National Airspace System Resource (NASR) 28-day subscription, which is public domain. Fix data comes from FIX_BASE.csv, FIX_CHRT.csv, and FIX_NAV.csv. The build pipeline that produces this dataset lives in tools/build-fix-data.
