Aviation

Aviation tools support flight planning and aircraft performance: weight and balance, fuel burn and endurance, the family of airspeed conversions, density altitude, crosswind components, and unit conversions specific to aviation. Accuracy matters more here than almost anywhere, so each tool follows the standard formulas pilots are taught and trained on.

Airspeed alone illustrates why these calculations exist. The number on the dial (indicated airspeed) must be corrected for instrument error, then for air density and altitude to get true airspeed, and finally adjusted for wind to get the ground speed that determines your actual time en route. Weight and balance is equally unforgiving: an aircraft loaded outside its centre-of-gravity envelope handles dangerously regardless of total weight. These tools make those checks quick and repeatable, running entirely offline in the cockpit or at the planning table.
