A pitot tube measures the pressure difference between still and moving air, then airspeed follows from v = √(2Δp/ρ). Because air thins with altitude, true airspeed exceeds the indicated value up high — a key gotcha in aviation. Educational tool.
Data Inspector
Air density1.225 kg/m³
True airspeed49.5 m/s
Indicated airspeed49.5 m/s
Mach number0.145
Governing equation
Reading this result: Near sea level the air is close to standard density, so true airspeed and indicated airspeed nearly coincide — the gauge reads reality directly.
