TS 2564

TS 2564 is a terminology standard for quantities used in measurements in flight dynamics. It establishes a common naming and symbol system for the measurement language used to describe aircraft motion and atmospheric conditions, helping ensure consistency in calculations, reports, and technical communication.

Measurement quantities grouped by technical function

According to its scope, the standard covers quantities used in measurements related to flight dynamics and organizes them into several groups. The scope explicitly mentions terms for atmospheric properties, fundamental altitudes, altitudes linked to local values of atmospheric parameters, and terms used in determining aircraft speed. This grouping helps separate concepts that are often related in practice but should not be confused in technical use.

In general technical context, flight-dynamics measurement terms support a precise language for altitude, speed, pressure, temperature, density, and related derived quantities. These terms are important because flight measurements often combine direct sensing with atmospheric corrections and derived values. A well-structured terminology standard reduces ambiguity between physical measurement, corrected values, and operational interpretations.

This TS was published as equivalent to ISO 2765:1974 and has since been withdrawn. It is therefore mainly of historical and reference value for terminology alignment rather than current standard-setting use.
