If air density changes due to weather, what adjustment is required in ballistic data?

• A. No adjustment.
• B. Adjust ballistic data to account for air density changes.
• C. Increase fuse time only.
• D. Decrease ammunition supply.

Answer: (B)

Air density affects how much drag a bullet experiences in flight. When weather changes, the density can become higher or lower, which speeds up or slows down the bullet’s deceleration and alters its range and drift. Ballistic data is built around a given air density; if that density changes, the data used to compute firing solutions becomes inaccurate. Updating ballistic data to reflect the current air density keeps range estimates, wind drift, and time of flight in line with actual conditions. Not adjusting would lead to mispredictions in where the round lands. Adjusting fuse time or ammunition quantity doesn’t address the aerodynamic effects of density changes on the projectile’s flight trajectory.
