Density Altitude & Air Density

Air density, density altitude (DA) and relative air density (RAD), computed with the precision that tuning an engine or planning a takeoff actually needs. WHY THIS APP • The barometer in your iPhone: the real pressure where you stand, with no network. • Density altitude, RAD or density on your widgets, Lock Screen and Apple Watch. • Alerts when conditions change during a session, even with the app closed. • Carburetor icing, read for a ground engine or for an aircraft. • Session logging with chart, CSV export and iCloud sync. • 4 dyno correction standards, so the factor matches your dyno sheet. • The full CIPM equation used in metrology, not an ideal-gas shortcut. WHAT IT CALCULATES • Air density (kg/m³, lb/ft³, lb/gal US, gr/ft³) • Density altitude • Relative air density (RAD) • Relative horsepower • Dyno correction factor • Dew point • Virtual temperature • Altimeter setting (QNH) •…
