How might one detect the plane of an accretion disc of a Black Hole? Might it just be assumed, by the orbital plane of a BH binary system? http://en.wikipedia.org/wiki/Accretion_disc"

Scientists use a variety of methods to detect black hole accretion discs. One common method is to observe the X-ray emissions from the heated gas as it falls towards the black hole. Other methods include studying the Doppler shifts of light from the disc and looking for changes in the brightness and temperature of the disc over time.
The main features of a black hole accretion disc include a bright inner region where the gas is heated to extremely high temperatures, and a cooler outer region where the gas is less dense. The disc also has a distinct shape, with the inner edge being closer to the black hole and the outer edge extending further out.
Black hole accretion discs form when a large amount of gas and dust is pulled towards a black hole by its strong gravitational pull. As the gas falls towards the black hole, it forms a disc due to the conservation of angular momentum. This disc then becomes the source of material for the black hole to accrete.
Yes, black hole accretion discs can provide valuable information about the properties of the black hole, such as its mass and spin. By studying the behavior of the accretion disc, scientists can also infer the strength of the black hole's gravitational field and the rate at which it is growing.
Since black hole accretion discs emit large amounts of radiation, there can be some risks associated with studying them. However, scientists take precautions to minimize exposure and use specialized equipment, such as telescopes and detectors, to safely observe and collect data from these discs.
