FormulaIntercept time = distance/sqrt(projectile**2-target**2); Lead distance = target*distance/sqrt(projectile**2-target**2); Lead angle = asin(target/projectile)*180/PI

How to use this tool

  1. Calculate an intercept for a target moving perpendicular to the initial line of sight.
  2. Set initial distance, projectile speed, perpendicular target speed in the indicated units.
  3. Calculate and compare intercept time, lead distance, lead angle.

{
  "distance": 100,
  "projectile": 50,
  "target": 30
}

Accuracy and scope

Idealized educational model. Enter measured values in the displayed units; real systems may require additional corrections. User-defined game-rule arithmetic; no current game mechanics or search-volume claims.
