    "data": {
        "note": "True airspeed = calibrated airspeed ÷ √(density ratio): thinner air reads low on the airspeed indicator, so TAS climbs above CAS with altitude and temperature (a rough 2 % per 1,000 ft). This is the incompressible form — fine for light aircraft; near and above the transonic range compressibility adds a further correction. Use TAS for navigation and ground-speed work; the wings still only feel CAS.",
