This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document is modified to adopt ISO 5224:2021 "Terminology for the flight dynamics of rotorcraft".

This document has undergone the following structural adjustments compared to ISO 5224:2021.

---Chapter 4 has been added;

---The "References" section has been removed;

--- An "index" has been added.

This document differs significantly from ISO 5224:2021.The relevant clauses are indicated in vertical single-line margins.
