TL;DR

you’re the pilot in command. Metar Echo provides weather intelligence and analysis, but you’re responsible for all go/no-go decisions. we’re an informational tool, not a substitute for your judgment or official weather briefings.

key points:

  • AI can make mistakes - always verify critical info
  • not a replacement for official FAA weather briefings
  • you own your data, we protect it
  • free tier (1 airport) + Plus subscription for advanced features
  • disputes go to arbitration (you can opt out in 30 days)
  • we’re not liable for weather-related decisions or incidents
  • weather data comes from FAA/NOAA/NWS and may be delayed or inaccurate
  • cancel Plus subscription anytime via Apple

this is the friendly version. the legal stuff below is binding.


Agreement to Terms

These Terms of Service (“Terms”) constitute a legally binding agreement between you (“End-User”) and Owyhee Holdings LLC, doing business as Metar Echo (“Metar Echo,” “we,” “us,” or “our”) regarding your use of the Metar Echo iOS application (the “App,” “Licensed Application,” or “Service”).

By using the App, you acknowledge that:

  • These Terms are concluded between you and Metar Echo only, and not with Apple, Inc.
  • Metar Echo, not Apple, is solely responsible for the Licensed Application and its content
  • You have read, understood, and agree to be bound by these Terms and our Privacy Policy

If you do not agree to these Terms, do not use the App.

Critical Aviation Safety Notice

AI-Generated Information Disclaimer

THE APP USES ARTIFICIAL INTELLIGENCE TO GENERATE WEATHER ANALYSIS. AI-GENERATED INFORMATION MAY BE INCOMPLETE, INACCURATE, OR INCORRECT.

  • Verify all information with official sources before relying on it for flight operations
  • Cross-check weather data against current FAA weather briefings
  • Confirm conditions with Flight Service or other official sources
  • Do not rely solely on AI analysis for critical safety decisions

Pilot in Command Authority

Per 14 CFR § 91.3 (Federal Aviation Regulations), the pilot in command is directly responsible for and is the final authority as to the operation of the aircraft.

The App is provided for informational and convenience purposes only. It does not:

  • Replace your responsibility as pilot in command
  • Substitute for official FAA weather briefings
  • Serve as the sole source for weather information
  • Override official weather sources or procedures
  • Constitute professional advice from a meteorologist

You remain solely responsible for:

  • Obtaining official weather briefings before flight
  • Verifying all weather information with authoritative sources
  • Making final go/no-go decisions
  • Operating within the limitations of your certificates and ratings
  • Ensuring safe flight operations

Informational Analysis Only

CRITICAL: The App provides INFORMATIONAL analysis only. It does NOT make operational decisions.

When the App provides weather analysis, it:

  • Presents data and conditions as they exist
  • May highlight trends or considerations
  • Does NOT make deterministic safety recommendations
  • Does NOT tell you whether it’s safe to fly

The App will NEVER state:

  • “Safe to fly”
  • “No issues”
  • “Good to go”
  • Or any similar operational clearance

You MUST:

  • Obtain official weather briefings from FAA-approved sources
  • Verify all data before flight
  • Make your own informed decisions
  • Never rely on the App as your sole weather source

Weather Data Accuracy

THE APP USES THIRD-PARTY WEATHER DATA SOURCES

We do NOT guarantee that weather data is:

  • Accurate or complete
  • Timely or current
  • Properly formatted
  • Free from errors or omissions

Weather data may be:

  • Delayed or outdated
  • Incomplete or missing
  • Incorrectly parsed or displayed
  • Different from official sources

Specific Weather Limitations:

METAR/TAF Data:

  • May be delayed from observation time
  • May be incomplete or missing elements
  • Parsing errors may occur
  • Always verify with official sources

PIREPs (Pilot Reports):

  • Provided as-is from FAA sources
  • May be outdated or inaccurate
  • Represent conditions at specific times/locations
  • Not predictive of current conditions

AIRMETs/SIGMETs:

  • Hazard detection is automated and may be incorrect
  • Boundaries may be imprecise
  • May not reflect the most current advisories
  • Always check official sources

Density Altitude:

  • Calculated from METAR data
  • Accuracy depends on data quality
  • Not a substitute for proper performance calculations
  • Verify with aircraft performance charts

Calculation Method:

// Density Altitude Calculation (Approximation)
// DO NOT USE FOR FLIGHT PLANNING - ESTIMATION ONLY

CONSTANTS:
  standardPressure = 29.92 inHg
  standardTemperature = 15°C
  pressureDeviation = 1000 ft per inHg
  temperatureDeviation = 2°C per 1000 ft

INPUT:
  fieldElevation (feet MSL)
  altimeterSetting (inHg)
  outsideAirTemperature (°C)

CALCULATE:
  // Step 1: ISA temperature at field elevation
  isaTemp = standardTemperature - (fieldElevation / 1000 × temperatureDeviation)
  
  // Step 2: Pressure altitude
  pressureAltitude = (standardPressure - altimeterSetting) × pressureDeviation + fieldElevation
  
  // Step 3: Density altitude
  densityAltitude = pressureAltitude + (120 × (outsideAirTemperature - isaTemp))

OUTPUT:
  densityAltitude (feet)
  pressureAltitude (feet)

User Responsibility:

  • Always obtain official weather briefings from 1800wxbrief.com or Flight Service
  • Verify all information before flight operations
  • Do not rely solely on the App for safety-critical decisions
  • Report data inaccuracies to us so we can improve
