Foreword

IS0 (the International Organization for Standardization) is a worldwide federation of

national standards bodies (IS0 member bodies). The work of preparing International

Standards is normally carried out through IS0 technical committees. Each member

body interested in a subject for which a technical committee has been established has

the right to be represented on that committee. International organizations, govern-

mental and non-governmental, in liaison with ISO, also take part in the work.

Draft International Standards adopted by the technical committees are circulated to

the member bodies for approval before their acceptance as International Standards by

the IS0 Council. They are approved in accordance with IS0 procedures requiring at

least 75 % approval by the member bodies voting.

International Standard IS0 1151/2 was prepared by Technical Committee ISO/TC 20,

Aircraft and space vehicles.

IS0 1151/2 was first published in 1974. This second edition cancels and replaces the

first edition, of which it constitutes a technical revision.

IS0 1151, Flight dynamics - Concepts, quantities and symbols,

comprises, at

present, seven parts :

Part 7 : Aircraft motion relative to the air

Part 2 . Motions of the aircraft and the atmosphere

relative

to the

Earth.

Part 3 : Derivatives of forces, moments and their coefficients.

Part 4 : Parameters used in the study of aircraft stability and control.

Part 5 : Quantities used in measurements.

Part 6 : Aircraft geometry.

Part 7 : Flight points and flight envelopes.

IS0 1151 is intended to introduce the main concepts, to include the more important

terms used in theoretical and experimental studies and, as far as possible, to give cor-

responding symbols.

In all the parts comprising IS0 1151, the term “aircraft” denotes a vehicle intended for

atmosphere or space flight. Usually, it has an essentially port and starboard symmetry

with respect to a plane. That plane is determined by the geometric characteristics of

the aircraft. In that plane, two orthogonal directions are defined: fore-and-aft and

dorsal-ventral. The transverse direction, on the perpendicular to that plane, follows.

When there is more than one plane of symmetry, or when there is none, it is necessary

to introduce a reference plane. In the former case, the reference plane is one of the

planes of symmetry. In the latter case, the reference plane is arbitrary. In all cases, it is

necessary to specify the choice made.

Angles of rotation, angular velocities and moments about any axis are positive

clockwise when viewed in the positive direction of that axis.

All the axis systems used are three-dimensional, orthogonal and right-handed, which

implies that a positive rotation through 7t/2 around the x-axis brings the y-axis into the

position previously occupied by the z-axis.

Numbering of sections and clauses

With the aim of easing the indication of references from a section or a clause, a decimal

numbering system has been adopted such that the first figure is the number of the part

of IS0 1151 considered.
