My understanding is that the JBM range card function uses density altitude. My understanding is also that the temperature inputs are for transonic calculations. Density altitude is pressure altitude corrected for temperature, and, to a minute extent, humidity. It is a measure of air density...It's also much more.

> Ballistic AE and BallisticsARC: These apps both run the JBM Ballistics solver, and had almost identical solutions. Within 1,000 yards, their predictions were spot on, except again for 0.2- to 0.3-mil deviations at 500 to 700 (sensing a pattern there …). Beyond that, they were off by about 0.1 to 0.2 mil.A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics. There can be as many model projectiles as there are different bullets, but which ballistic coefficient type is used depends on the model and how ...A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics.

Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x is to the shooters right and z is up. Then rewrite the derivative d u / dt a = d u / dt = (d u / dy) (dy/dt) = - k (u - w)+ g. But dy/dt is just the velocity in the y direction (down range) written u y, then

In ballistics, the ballistic coefficient ( BC) of a bullet is a measure of its ability to overcome air resistance in flight. A high BC means it will slow down less. It will have more of its speed left when it reaches the target. BC depends on mass, diameter, and drag coefficient. Ballistic coefficient has units of lb/in² or kg/m².Read reviews, compare customer ratings, see screenshots and learn more about Ballistic: iPad Edition.
