coolAltitude is a professional support tool 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/

Version 4 expands coolAltitude from a temperature correction calculator into a comprehensive cold-weather operations support tool for IFR pilots. New and improved features include: • Saved and reloadable approach presets for individual airports and procedures • Integrated METAR interaction with automatic propagation of relevant values • Full de-/anti-icing support based on FAA Holdover Time (HOT) Guidelines • Built-in HOT countdown timer to support situational awareness during ground operations • Structured storage and sharing of verified operational data • Improved workflow clarity and reduced data entry requirements This release focuses on accuracy, clarity, and usability during high-workload flight preparation. 4.2 Jan 9 This update significantly expands coolAltitude from a temperature correction calculator into a comprehensive cold-weather operations support tool for IFR pilots. New and improved features include: • Saved and reloadable approach presets for individual airports and procedures • Integrated METAR interaction with automatic propagation of relevant values • Full de-/anti-icing support based on FAA Holdover Time (HOT) Guidelines • Built-in HOT countdown timer to support situational awareness during ground operations • Structured storage and sharing of verified operational data • Improved workflow clarity and reduced data entry requirements This release focuses on accuracy, clarity and usability during high-workload flight preparation. 4.1 Jan 5 This update significantly expands coolAltitude from a temperature correction calculator into a comprehensive cold-weather operations support tool for IFR pilots. New and improved features include: • Saved and reloadable approach presets for individual airports and procedures • Integrated METAR interaction with automatic propagation of relevant values • Full de-/anti-icing support based on FAA Holdover Time (HOT) Guidelines • Built-in HOT countdown timer to support situational awareness during ground operations • Structured storage and sharing of verified operational data • Improved workflow clarity and reduced data entry requirements This release focuses on accuracy, clarity and usability during high-workload flight preparation. 4.0 12/30/2025 • Updated for iOS 26 • Minor UI and performance improvements 3.5 10/23/2025 Improved readability and minor enhancements for a better user experience. 3.4 01/22/2025 • Fixed an issue where the temperature display would reset to -5°C. • Optimised for iOS 18 for smoother performance. 3.2 09/27/2024 coolAltitude has been completely reworked using the lates available technology. iPad versions now supports portrait and landscape orientations including split view over another app. Overall stability has been significantly improved. App now supports dark mode, which can be triggered regardless of the system settings to make night approaches more comfortable. 3.0 03/25/2024 New features added: • RCAM table view • Different temperature correction calculation methods: o ICAO 8168 (current) o 10% | 20% of HAT (or QNH source) o 4% of HAT (or QNH source) on each 10°C of ISA DEV o Table values with linear interpolation • Option to use default rounding principles or to display precise values The look & feel was freshened and some bugs from previous version corrected. 2.4 11/21/2021 IOS 13 compatibility. 2.2 09/27/2019 iPhone X, XR, XS compatibility 2.1 11/05/2018 Compatibility for IOS 11 Improved screen layout for different devices Added temperature corrections calculation up to +10°C Added support for higher temperatures (more than 22°C) – it calculates the “actual flown” descent path, which is higher than the selected one Added support for degrees of Fahrenheit 2.0 10/02/2017 Modification of the height over the runway threshold used for profile calculation is enabled. Quick switch between profiles calculated to runway threshold and profiles calculated to runway touch down zone. This is useful feature for LOC/DME approaches as ILS DME is very often collocated with G/S antenna and thus reads zero at TDZ. Improved help guide 1.9 12/19/2016 Compatibility for IOS 10 1.8 09/20/2016 Minor improvements related to IOS 9 1.7 12/14/2015 Improved formatting for long approaches. Now it can display readable results for approaches up to 22 nm long. 1.6 07/17/2015 Now the coolAltitude is available on iPads and iPhones You can zoom in and out to different parts of the approach and corresponding values Fonts used for numbers are larger 1.5 04/22/2015 coolAltitude can now calculate altitude corrections for MSA and Go Around altitudes. 1.4 10/10/2014 SNOWTAM decoding from METAR information has been added. It can also now transform friction coefficients reported in SNOWTAM to braking actions based on ICAO scale and Normative/CIS scale respectively. coolAltitude can recommend possible BA based on runway contaminant reported in SNOWTAM combined with reported airport temperature. This feature is experimental and if used it must always be crosschecked with valid QRH/FCOM approved by the operator. The contaminant must be verified by ATIS. coolAltitude can be used in real operation if the operator did receive an approval from corresponding DGCA/CAA authority. coolAltitude must be in that case part of authorized software in operator’s EFB package. 1.3 08/27/2014 IOS 7 compatibility 1.2 11/15/2013 • Corrected recalculation bug when changing decision altitude • Improved and more precise input of values including rounding of entered values • Other minor changes 1.1 05/09/2013 1.0 05/02/2013
