Airspeed Sensor Calibration and Accuracy

Verified from official sources
Appendix 6, Part 2Version 1Effective -Verified 31 August 2026

In plain language

The drone's airspeed sensor must be calibrated so that its measurement error does not exceed 3% or 5 knots (9.3 km/h) under standard sea-level conditions.

Requirement as structured

CAAS guidance states that the airspeed measurement sensor must be calibrated to measure true airspeed at sea-level with a system error not exceeding 3% of the calibrated airspeed or 9.3 km/h (5 knots).

Original regulatory text

Throughout the flight envelope, the airspeed measurement sensor must be calibrated to measure true airspeed at sea-level with a standard atmosphere and within a system error not exceeding 3% of the calibrated airspeed or 9.3 km/h (5 knots).
