## What is DZ Ballistics?

DZ Ballistics is designed to give airdrop aircrews accurate ballistic wind and drop information for HALO and HAHO airdrops using data from AFI 11-231. 

Calculating an average wind is not as simple as it seems. A vector computation is required.

The entered or downloaded wind data can be used for pre-flight planning and briefings, as well as inflight updates to enhance aircrew situational awareness.

A picture is worth a thousand words and the Wind Circle Graphic gives you an instant visualization of the entered winds.

DZ Ballistics makes wind calculations a breeze.

All reasonable efforts are made to ensure accuracy of the information. As always, the respective Air Force Instruction is the governing directive.

   ⁃ For North American locations, Rapid Refresh (RAP) is a regional weather forecast model with separate sub-grids (with different horizontal resolutions) within the overall North America domain. RAP produces forecasts every hour with forecast lengths going out 18 hours. 
   ⁃ Outside North America (or beyond 18 hour RAP limit), the Global Forecast System (GFS) model is a coupled weather forecast model, composed of four separate models which work together to provide an accurate picture of weather conditions. GFS covers the entire globe down to a horizontal resolution of 28km. (Data requests from the GFS model may require multiple attempts.)

• Removed all third-party analytics and crash reporting. (Your feedback has become more critical than ever. Please share any issues or problems using the in-app Feedback link or via www.tacticalEFB.com.)
