My Airport Weather

What's New: NEW: Carburetor Icing Risk Assessment • Real-time assessment based on temperature and humidity • Color-coded risk levels: Low, Moderate, Serious, Severe • Specific recommendations for each risk level • Special warnings for severe conditions • Toggle on/off in Settings (Safety Features section) Enhanced Safety Features • New "Safety Features" settings section • Carburetor icing display can be customized to your preference • Smart display: only shows when conditions warrant attention Default setting change • Default pressure unit changed to inHg (US aviation standard) Enhanced Airport Database • Updated airport list with previously missing airports • Improved coverage for better airport selection This update adds a powerful new safety tool to help pilots assess carburetor icing risk in real-time. The risk assessment considers temperature, humidity, dew point spread, and visible moisture conditions. Perfect for pilots flying aircraft with carbureted engines! Stay safe and fly smart!

Version 1.3.1 - Bug Fixes and Improvements What's New: • Fixed weather data display issue for airports without TAF forecasts • Improved time display in navigation bar for latest iOS versions • Enhanced data fetching reliability Bug Fixes: • Resolved issue where some airports would fail to load weather data • Fixed Zulu time display being truncated on newer iOS devices • Improved handling of empty forecast responses We've made My Airport Weather even more reliable! This update ensures you get accurate weather information for all airports and fixes display issues on the latest iOS versions. Thank you for using My Airport Weather!

## [1.3] - 2025-08-11 ### Added - **Fractional Visibility Support**: Enhanced METAR parsing to correctly handle fractional visibility values (e.g., "3/4SM", "1 1/4SM") - **Low Level Wind Shear (LLWS) Detection**: Added comprehensive parsing and display of wind shear information from raw METAR data - **CAVOK Condition Handling**: Implemented support for "Ceiling And Visibility OK" conditions, displaying "Visibility OK" and "Ceiling OK" appropriately - **Density Altitude Calculation**: Added computed density altitude field using precise aviation formula including temperature, pressure, humidity, and airport elevation - **Airport Elevation Integration**: Enhanced airport data loading to include elevation information from airports.csv for accurate density altitude calculations - **Enhanced UI Layout**: Improved readability and alignment across iPhone and iPad interfaces ### Changed - **iPhone Landscape Layout**: Reorganized weather information into logical rows for better readability: - Row 1: METAR Age - Row 2: Temperature, Dew Point, Wind - Row 3: Visibility, Altimeter, Density Altitude - Row 4: Clouds, RVR, LLWS, Weather Phenomena - **iPad Layout Optimization**: Split main weather line into multiple rows for improved readability and consistent alignment - **Visibility Parsing**: Updated regex patterns to handle fractional visibility values with improved accuracy - **Flight Category Logic**: Enhanced to properly handle CAVOK conditions and fractional visibility values - **Density Altitude Formula**: Implemented precise calculation using WMO vapor pressure formula and airport elevation ### Fixed - **Fractional Visibility Bug**: Corrected issue where "3/4SM" was incorrectly interpreted as "4SM" - **LLWS Display**: Fixed wind shear information parsing and display with appropriate labeling ("Wind Shear" vs "Low Level Wind Shear") - **UI Alignment Issues**: Resolved inconsistent spacing and alignment across different device orientations - **Cloud Info Alignment**: Fixed alignment of cloud information field in iPad view to match other row elements - **Caching Issues**: Temporarily reduced cache expiration for testing and debugging density altitude calculations - **Airport Elevation Parsing**: Fixed parsing of decimal elevation values from CSV file ### Technical Improvements - **Enhanced Regex Patterns**: Improved pattern matching for visibility, wind shear, and other METAR elements - **Debug Logging**: Added comprehensive debug output for density altitude calculations and airport elevation loading - **Data Structure Updates**: Extended MetarData and DetailedWeather structs to include new fields (llws, densityAltitude) - **Error Handling**: Improved error handling for edge cases in METAR parsing and calculations

Fixed few bugs. Improved the airport list to only display the one with METAR/TAF. Improved the overall response time on the selection of airports.

Few bugs corrected.
