GB/T 14410.4-2008Flight mechanics - Concepts, quantities and symbols - Part 4: Flight performance (English PDF)

Foreword

GB/T 14410 "Flight mechanics - Concepts, quantities and symbols" is divided into nine sections.

--- Part 1. Axis systems and motion state variables;

--- 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 Part of 414,410. This Part replaces GB/T 14410.4-1993 "Flight mechanics - Concepts, quantities and symbols - Part 4. flight performance." Section compared with the GB/T 14410.4-1993 The main changes are as follows:

a) increase the "

3.8.1 life" and other definitions;

b) modify the "minimum control speed air 3.3.4", "

3.3.9 takeoff ground speed", "

1 Scope

GB/T 14410.4-2008 is the Chinese national standard on flight mechanics - concepts, quantities and symbols - part 4: flight performance, in the field of aircraft and space vehicle engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 18 July 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009. Classification: ICS 49.020, CCS V04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section provides a description of the aircraft flight performance of terminology and symbols. This section applies to fixed-wing aircraft, other aircraft can use the reference.
