Dynamic pressure Δp (Pa)

Altitude (m)

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.

▶ Run in Python

Data Inspector

Air density1.225 kg/m³

True airspeed49.5 m/s

Indicated airspeed49.5 m/s

Mach number0.145

Governing equation

v = \frac{2 ( p _{0} - p _{s} )}{ρ} = \frac{2 \cdot 1500}{1.225} = 49.5 m/s

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.
