--- Part 2. Forces, moments, their coefficients and derivative;

--- Part 3. aircraft stability and control;

--- Part 4. flight performance;

--- Part 5. flight measurement;

--- Part 6. Aircraft geometry;

--- Part 7. Flight points and flight envelope;

--- Part 8. dynamic characteristics of the aircraft;

--- Part 9. atmospheric disturbance model.

This section GB/T 14410 Part 6.

The partial modification of the use of ISO 1151-6. 1982/Amd1. 1984 "aircraft flight dynamics geometry terminology and symbols." this Part of ISO 1151-6. 1982/Amd1. 1984 The main difference is the addition of "shafting aircraft structure, the trailing arm horizontal tail, vertical tail Trailing arm "and other terms.

This Part replaces GB/T 14410.6-1993 "Flight mechanics - Concepts, quantities and symbols - Part 6. Aircraft geometry." Section compared with the GB/T 14410.6-1993 The main changes are as follows.

a) increase the "reference axis components 3.1.6", "3.5.8 center chord length" and other terms and definitions;

b) Modify the "3.5.11 wing trapezoid ratio" is "3.5.12 aircraft wingtip root ratio" and other definitions;

c) modify the terms and definitions have a number of references to other clauses marked;

d) increasing the dimension of the unit, and indicated in the symbol bar;

e) an increase in the English index.
