Cold Weather Altitude Correction is a tool for visualizing and calculating approaches at low temperatures. In addition you will find a decoder for METAR RWY Reports. The calculation is based on ICAO PANS OPS Doc 8168. It uses a more accurate method as the well-known 4 per correction, which becomes imprecise for temperatures below -15ยฐC. Conventional tools are calculating only a list of temperature corrected altitudes. This tool is designed more closely to a real approach. Corrected altitudes are presented in a graphical interface. A table of distances with related corrected altitudes can be calculated. With only field elevation and temperature a graphic layout will be shown: - glide path down to the runway - corrected MSA - corrected MDA - corrected GPA - corrected custom ALT Moving a yellow dot along the glide path down to the runway will show any corrected altitudes with their related distances to threshold or to a DME station. Distance - Altitude Table: A table with distance and corrected altitude can be calculated.ย  This table is similar to the distance / altitude tables known from instrument approach charts, but it will show corrected altitudes. You can choose between an approach type based on "distance to threshold" (GPS) or based on a defined DME station. A handbook is included in the app itself. For night operations you can switch to dark mode.
