Hi All,
Realise we're talking about the A330 here, but on the A320 one can intercept a radial by using the DIR TO function. Press DIR TO and on the 3R or 4R (cant recall exactly), there is a RADIAL IN and RADIAL OUT blank box. Insert the appropriate radial in this field. The aircraft wil continue ahead until intercepting the radial. (think one needs to pull HDG mode first),......
Something like that anyways
