In American usage, the angle between the chord line of a wing and the flight path is called the "angle of attack". The angle of attack is also represented by the greek letter "alpha". However, some British authors, especially in the past, have referred to this angle as the "angle of incidence". (See one supporting reference here.)
We'll call this the "older British" use of the term "angle of incidence". How common is this usage now in the British aviation world? Has it completely fallen by the wayside, or is still common? Was it ever very common?
Also, what term or terms did authors and speakers following this "older British" usage, use to refer to the angle between the wing chord and the longitudinal axis of the fuselage (or some other similar defined datum line approximating the longitudinal axis of the fuselage?) Some of the terms that have been used for this angle by writers and speakers following the "older British" usage noted above, appear to include "rigger's angle" and "rigger's angle of incidence". Are there others?
(In American usage, this latter angle is in fact the angle that is called the "angle of incidence".)
(Bonus extra part: is there one particular greek letter that is normally assigned to this latter angle in engineering texts and papers, much as "alpha" is normally assigned to the angle that is described in the first paragraph of this question?)
