It would also be nice if we could all agree that yaw, pitch, and roll
are not angles but angular rates. The names of the angles are heading,
elevation and bank angle, as per "Quaternions and Rotation Sequences" by
Jack B. Kuipers page 85. That however would probably require fixing this
page which is just a disaster but sort of explains the scope of the
problem. http://en.wikipedia.org/wiki/Talk:Yaw,_pitch,_and_roll

Maybe in aerial robotics there is a different convention for naming orientations and angular rates, but that does not make it _wrong_ to call it differently in other application domains. In fact, it is not uncommon in the general robotics literature to use the terms roll, pitch and yaw  to refer to a specific Euler/fixed angle combination (c.f. Section 2.8 of Craig's Introduction to Robotics, citation below, for an example). The important thing is to document unambiguously the used conventions.
