and to supply electricity to the experiments. During the flight, power is generated by
the internal airplane system. The switch-over from external to internal power supply is
done before the airplane starts to roll and after experimenters have been seated and
fastened seat belts. This means that the electrical supply will be interrupted for some
minutes. The experimenters are not allowed to stay aside their experiments in this
period, but may access their experiments some minutes after take-off, i. e. 5-10 minutes
before the first parabola. At that time it is possible to reinitialize or restart their system.
This time will be, if possible, maximised to allow for experiment preparation. If this
hampers the experimental procedure experimenters are asked to inform Novespace
before the security review.
Momentary interruptions of electrical power may occur during flight. Although
infrequent, these interruptions may disrupt certain sensitive instruments, and test
equipment should incorporate protection devices to prevent data loss. In case of sudden
loss of electricity the experiment has automatically to pass into a safe status,
e. g. gas lines to be closed, flames off, etc..
Each experiment has to be equipped with an red emergency push button to switch off
the 220 V and the 28 V. The button has to be accessible from the experimenter's seat or
position.
The experiments' electrical instruments must not interfere with the aircraft systems and
instruments, and must meet the safety standards for electromagnetic compatibility of
equipment on board.

3.4 Overboard Vent System
No gas, liquid or material, even known as not toxic, can be released from an experiment
into the aircraft cabin. Four connections to outside atmosphere are located at the four
extremities of the experimentation room and allow manual or automatic gas/liquid
venting. The necessary connections must correspond to the Pneurop 6606/1981 and
DIN 28403 with a connection diameter of DN 25 ISO-KF. The connections and tubes
must be supplied by the experimenting parties themselves. If evacuation lines are to be
used kind, pressure and temperature of the elements to be evacuated have to be made
available to Novespace.

4.1 Safety Policy
The A300 Zero-G parabolic flight programme is operated in accordance with stringent
safety procedures established by the French "Centre d'Essais en Vol". The exploitation
in microgravity is done under an exceptional "Laisser-Passer" signed by the General
Direction of Civil Aviation in France. The flights are regarded as test flights and as
such fall under the rules for test flights, under the authority of the "Centre d'Essais en
Vol". Due to the critical nature of this programme, a multi-stage review and approval
procedure has been developed to ensure flight safety. Approval from multiple
authorities is required prior to flight.
In particular, the test experimenter must submit to Novespace relevant documents at
different stages of the project (including experiment description and hazard analysis).
In addition, all test personnel must follow Novespace requirements and attend a final
safety review and safety visit prior to flight. These items are described in the following
chapters.
The degree of detail, rigor, and formality required in the development and conduct of a
reduced gravity test depends on the complexity, hazards, and uniqueness of a test.
Communications with Novespace are required early and often to eliminate any last
minute surprises which might cause delays. Relevant personnel will review and
comment on preliminary drawings and plans at all stages of development. It should be
noted that a flight will be conducted only after Novespace and CEV have been assured
that a safe, well organized, and productive flight can be achieved.
User Procedures Chapter 4
Edition 5.2 4.2
During the flights, all personnel on board the aircraft will be under the direction of the
aircraft flight crew and test directors for the entire duration of a campaign. The aircraft
commander is the final authority for all operations from boarding to deplaning.
Strict adherence to the authority of test personnel will be rigidly enforced. Any
deviation from the flight-test plan must be discussed with Novespace before its
implementation.
4.2 Documentation requested
Three months prior to flight, the test experimenter should forward to Novespace a
document containing general information. This package should contain:
1. Test Objectives
2. Brief description of the test and associated test equipment (Please note
