iii) From point B, draw a straight line splaying apart from the DR track at a 22° angle (heading tolerance
plus maximum drift angle for the lowest speed category).
iv) Locate A' on the OAS X surface abeam the FAF.
v) From A' draw a straight line splaying at 15° from the intermediate approach track to a point C abeam
the IF.
vi) From C draw a straight line parallel to the intermediate approach track.
