ColdCalcMDA is a Cold Temperature Altitude Correction Calculator used by pilots to correct their Minimum Descent Altitude (MDA) for an instrument approach. Pilots input the charted Airport Elevation and MDA then "slide" in the reported temperature. The MDA correction (to be added) as well as the corrected results are clearly displayed dynamically in real time! All IFR Pilots, from Private to Airline will welcome the ease of use of this muchneeded utility on their Flight Decks!This FREE version of ColdCalcMDA is identical to the full version except:1- it contains an advertisement banner2- The temperature input is restricted from -35c to -50c. The full version of the app slides from 0c to -50cNOTE: THIS FREE VERSION CONTAINS iAds & THEREFORE REQUIRES IOS 4.0 OR GREATER TO RUN ON YOUR DEVICE
