Cold Weather Ops

Cold Weather Ops is an app that gives simple and intuitive access to information that would otherwise require pilots to troll through pages and pages of documents, or make critical calculations based on tabulated information.

The app includes:-
 
Snowfall Intensity - Make 3 simple selections to find out the snowfall intensity for use in Holdover Time calculations.
 
Holdover Times - A simple and intuitive interface to gain access to anti-icing holdover times, based on the current FAA Guidelines tables. The form builds in a logical sequence, with all notes (including restrictions, Lowest Operational Use Temperatures, condition descriptions, etc) appearing at the relevant points in the process - avoiding the need to have to troll through pages of documents. Once a holdover time has been generated, a timer is available to set a reminder for when the holdover time has expired.

Runway Conditions - A tool to quickly gain information about generic Braking Action and Runway Condition Code associated with the various types of runway contaminants. A description of each condition is provided along with what can be expected with the different Braking Action levels. Also included is a simple calculator to work out the runway cleared width in metres, when given by ATC in feet (when required for reducing maximum crosswind figures). Holdover Data is updated each winter to reflect the latest FAA guidelines.

Altimeter Corrections - By using the mathematical formula from ICAO Doc 8168, this tool provides accurate altimeter information for flying approaches in colder than standard conditions - removing the need to make calculations/interpolation of tabulated figures.

Annual subscription required to use this app.
