Paragraph 7D Equipment, Assemblies and Components

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

Software

7D001

Software specially designed or modified for the development or production of goods specified in sub-categories 7A or 7B.

7D002

Source code for the use of any inertial navigation equipment or Attitude Heading Reference Systems (AHRS) (except: gimballed AHRS) including inertial equipment not specified in entries 7A003 or 7A004.

  • Note: AHRS generally differ from inertial navigation systems (INS) in that an AHRS provides attitude heading information and normally does not provide the acceleration, velocity and position information associated with an INS.

7D003

Other software, as follows:

a.

Software specially designed or modified to improve the operational performance or reduce the navigational error of systems to the levels specified in entries 7A003 or 7A004;

b.

Source code for hybrid integrated systems which improves the operational performance or reduces the navigational error of systems to the level specified in entry 7A003 by continuously combining inertial data with any of the following navigation data:

1.

Doppler radar velocity;

2.

Global Positioning Satellite (GPS) references; or

3.

Terrain data base;

c.

Source code for integrated avionics or mission systems which combine sensor data and employ knowledge-based expert systems;

d.

Source code for the development of:

1.

Digital flight management systems for flight path optimization;

2.

Integrated propulsion and flight control systems;

3.

Fly-by-wire or fly-by-light control systems;

4.

Fault-tolerant or self-reconfiguring active flight control systems;

5.

Airborne automatic direction finding equipment;

6.

Air data systems based on surface static data;

7.

Raster-type head-up displays or three dimensional displays.

7D101

Software specially designed for the use of goods specified in entries 7A001 to 7A006, 7A101 to 7A106, 7A115, 7B002, 7B003, 7B102 or 7B103.

7D102

Integration software for the goods specified in entries 7A003 or 7A103.

7D103

Software specially designed for modelling or simulation of the guidance sets specified in entry 7A117 or for their design integration with the systems specified in entries 9A004 or 9A104.

  • Note: Software specified in this entry remains controlled by this entry when combined with specially designed hardware specified in entry 4A102.
