Long Range Shooting

Long range shooters need some of the most precise calculations in order to make extremely accurate shots in different settings and conditions. Know the effects of station pressure and density altitude on bullet flight.


Constantly changing weather conditions make real-time flight decisions crucial for pilots in small aircraft and helicopters. Prevent takeoff and landing accidents by accurately measuring density altitude and adjusting flight operations depending on the area’s high or low density altitude.


Skydivers depend on density altitude to make decisions involving canopy size. Proficient parachutists may select smaller canopy sizes for routine jumps but may actually want to up size to a larger canopy in high density altitudes. Higher density altitudes may also indicate a faster canopy descent.
