  Radio maps of AGNs often show linear features, called jets, both on pc as
well as kpc scales. These jets supposedly possess relativistic motion and are
oriented close to the line of sight of the observer and accordingly the
relativistic Doppler beaming makes them look much brighter than they really are
in their respective rest-frames. The flux boosting due to the relativistic
beaming is a very sensitive factor of the jet orientation angle, as seen by the
observer. Quite often large bends are seen in these jets, with misalignments
being $90^\circ$ or more and might imply a change in the orientation angle that
could cause a large change in the relativistic beaming factor. Such large bends
should show high contrasts in the brightness of the jets, before and after the
misalignments, if relativistic beaming does play an important role in these
jets. It needs to be kept in mind that sometimes a small intrinsic change in
the jet angle might appear as a much larger misalignment due to the geometrical
projection effects, especially when seen close to the line of sight. Of course
what really matters is the final orientation angle of the jet with respect to
the observer's line of sight. Taking the geometrical projection effects
properly into account, we calculate the consequences of the presumed
relativistic beaming and demonstrate that there ought to be large brightness
ratios in jets before and after the observed misalignments.
