Cold Temperature Corrections – Professional Aviation Tool When outside air temperature is colder than ISA, an aircraft’s true altitude is lower than the indicated altitude—reducing terrain and obstacle clearance. To mitigate this risk, regulations require pilots to apply cold temperature corrections. The Cold Temp App streamlines this process with fast, accurate calculations based on the ICAO Cold Temperature Correction Table or precise engineering equations, ensuring compliance with ICAO PANS-OPS and FAA TERPS. In its latest revision, the app has been enhanced with additional modules: • ATMOS Module – Advanced atmospheric calculations, ISA parameters, and air data conversions. • CDFA Module – Constant Descent Final Approach planning with integrated cold temperature corrections. With expanded capabilities, regulatory compliance, and operational accuracy, the Cold Temp App is an essential professional tool for safe and efficient flight operations in cold-weather environments.

If I want to purchase another app I will - I don’t need to be force feed app suggestions every 2 seconds. Turn them off! ### 1/5 — Free but can’t use it at all without subscription *2023-09-10* Can’t use without paying the subscription even though the app is “free” ### 1/5 — Unacceptable bugs *2023-04-21* App is a brilliant tool to convert cold weather altitudes. Has enough labels and unlabeled fields, to convert even approaches with multiple additional step downs in addition to the usual 3 or 4. It is however, very unreliable, for it randomly forgets that you already have a subscription prompts you to purchase one, when you are just about to convert your altitudes. **Developer response:** Dear Zimzon, I just released a new version 2.1 that should fix this issue. Please, let me know if you face this issue again? ## Frequently asked questions about ColdTempCorr ### What is ColdTempCorr used for?
