A. PREPARING YOUR EXPERIMENT
Things to bring
Be conscious that you are responsible for everything required to perform your
experiment. You should bring all the ground support equipment, test samples, tools,
spare parts, consumables, test equipment, etc., that your experiment requires. Unless
you have checked first, don't assume that anything will be available on the aircraft base.
Preparing your experiment
One of the best features of parabolic flight is that it can be used very much like any
other laboratory, albeit a rather crowded one. Many experiment packages look very
much like they would in any laboratory except for greater compactness and some
judicious padding. There are some exceptions to this :
· If hard disk readers are to operate during pull in or pull out phases of the
parabola, it is advised to set them upright to avoid any read or write errors
occurring under high load factor (close to 2g).
· Since the experiment package will be compact and the aircraft crowded, be
sure to have every item you need to access on one single side of your
experiment, in front of which you will be most likely lying or sitting.

Edition 5.2 A5.2
· Take care to avoid interference between your own pieces of equipment. Due to
the compactness of the experiment, it is likely that you will experience some
electro-magnetic interference between your electrical and measurement
components. You must test the equipment in a lab in exactly the same physical
configuration it will have in the aircraft. You will also have to carefully connect
the ground of each electric or electronic equipment to the common ground.
The sensitive parts of your experiment (measurement, teledetection...) could
also receive interference from other experiments or from the aircraft. Be sure
that the sensitive parts have a special electromagnetic shelter.
· Verify that the cooling openings of your equipment are not obstructed by
padding or by other equipment.
· For some experiments, high electrostatic loads in the aircraft could be a
problem (dust or small particles behaviors...)
To pass the safety review, build or modify your apparatus with common sense in mind.
Use sensible labeling on switches and indicators. Have interlocks on critical controls.
Have a "panic button" to shut off your system in case of a serious problem. It is
imperative that critical items are properly documented and tagged. Double-check that
your structural elements can handle the specified loads.
The importance of proper documentation, certification and tagging of critical items
cannot be overemphasized. Most experimenters have equipment that is intrinsically
safe, but in the past, some have not properly demonstrated and documented these facts
to the Safety Visit committee's satisfaction.
Suggestions for Flight Appendix 5
Edition 5.2 A5.3
If your apparatus is heavy, bolt on handles on strategic locations. If it is very heavy,
bolt on removable wheels or bring a small dolly. Keep fragile components and wiring
well away from lifting locations.
Many people will be walking or floating close to your experiment. Thus, protect
exposed switches on your apparatus, use plenty of foam padding, particularly on sharp
corners and edges. Bolt a sheet of LEXAN or non-flammable Plexiglas over your video
monitor.
Experimental Procedures
The number of operations that can be carried out in twenty seconds is of course
limited. Only essential operations should be executed during this time, to make the best
use of the period of microgravity.
