FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
International Standards is carried out through IS0 Technical Committees. Every
Member Body interested in a subject for which a Technical Committee has been set
up has the right to be represented on that Committee. International organizations,
governmental 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.
International Standard IS0 1152 was drawn up by Technical Committee
lSO/TC 20, Aircraft and space vehicles.
It was submitted directly to the IS0 Council, in accordance with clause 6.12.1 of
the Directives for the technical work of /SO.
This International Standard cancels and replaces IS0 Recommendation
R 1152-1969, which had been approved by the Member Bodies of the following
countries :
Israel Sweden
Belgium
Czechoslovakia Italy Switzerland
of Netherlands Turkey
Egypt, Arab Rep.
France New Zealand United Kingdom
Germany Poland Yugoslavia
India Spain
The Member Bodies of the following countries had disapproved the

International Standard IS0 1152, Terms and symbols for flight dynamics -
Part II : Motions of the aircraft and the atmosphere relative to the Earth, is the
second in a series of International Standards, the purpose of which is to define the
principal terms used in flight dynamics and to specify symbols for these terms.
Other International Standards in this series, which will be further extended in the
future, are at present as follows :
IS0 1151, Terms and symbols for flight dynamics - Part I : Aircraft motion
relative to the air.
IS0 1153, Terms and symbols for flight dynamics - Part 111 : Derivatives of forces,
moments and îheir coefficients.
IS0 2764, Terms and symbols for flight dynamics - Part IV : Parameters used in
the study of aircraft stability and control.
IS0 2765, Terms and symbols for flight dynamics - Part V: Quantities used in
measurements.
In these International Standards, the term "aircraft" denotes an aerodyne having a
fore-and-aft plane of symmetry. This plane is determined by the geometrical
characteristics of the aircraft. When there are more than one fore-and-aft planes of
symmetry, the reference plane of symmetry is arbitrary and it is necessary to
indicate the choice made.
Angles of rotation, angular velocities and moments about any axis are positive
clockwise when viewed in the positive direction of the axis.
All the axis systems used are three-dimensional, orthogonal and right-handed, which
implies that a clockwise (positive) rotation through n/2 about thex-axis brings the
y-axis into the position previously occupied by the z-axis.
Numbering of sections and clauses
Each of these International Standards represents a part of the whole study on terms
and symbols for flight dynamics.
To permit easier reference to a section or a clause from one part to another, a
decimal numbering has been adopted which begins in each International Standard
with the number of the part it represents.

2.0 INTRODUCTION
This International Standard deals with the motions of the aircraft and the atmosphere relative to the Earth.
In this International Standard.
1) the effects of the Earth's curvature are not considered; for the purpose of the definition of Earth axes, the Earth's
surface is treated as
