coolAltitude vs Flight Bag

coolAltitude is a professional aviation tool and calculator for IFR pilots operating in cold-weather conditions. It assists with temperature corrections during instrument approaches and integrates weather, runway and de-/anti-icing data into a single, clear workflow. Designed to reduce workload and improve situational awareness during flight preparation, coolAltitude focuses on accuracy, clarity and operational usability. Some advanced features require a paid subscription. -------------------------------- What coolAltitude does • Calculates temperature-corrected altitudes for ILS (CAT I), RNAV/GNSS, VOR and NDB approaches • Requires minimal data entry, using consistent color coding for immediate interpretation • Displays corrected altitudes along the entire approach profile at relevant DME distances • Supports flight path angle (FPA) calculations for FPA-enabled aircraft • Provides vertical speed reference tables (corrected and uncorrected) for various ground speeds • Includes QNH to QFE conversion tables with temperature corrections -------------------------------- Integrated weather and runway information • Live METAR interaction with automatic propagation of relevant values, including temperature (requires subscription) • SNOWTAM decoding with braking action information • RCAM (Runway Condition Assessment Matrix) based on ICAO GRF • Support for DME shift, including threshold, touchdown zone and displaced DME references -------------------------------- De-/Anti-icing support (requires subscription) • FAA Holdover Time (HOT) Guidelines for multiple fluid types and manufacturers • Integrated HOT countdown timer to track minimum and maximum recommended holdover times • Reference tables supporting assessment of snowfall intensity • Structured storage and sharing of airport-specific de-/anti-icing procedures -------------------------------- Saved and shared data (requires subscription) • Save and reload approach presets for individual airports and procedures • Share verified, structured operational data with other users • Local override of shared data when required -------------------------------- Built for professional use coolAltitude is built by pilots, for pilots. It is designed to support decision-making during high-workload phases without replacing approved procedures. -------------------------------- Important notice coolAltitude is an advisory tool only. It is not certified for operational use and does not replace approved documentation. Use in flight operations requires approval and operation as part of the operator’s Electronic Flight Bag (EFB) in accordance with applicable regulations. -------------------------------- coolAltitude does not replace your procedures. It helps you apply them correctly, even on the coldest days. -------------------------------- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
