90 degree DVOR in-cruise turn.
On my way back, in 1986, from Brindisi, in the heel of Italy, to Luton, our Britannia 737-200ADV was required to perform an almost 90 degree left turn at Vicenza VOR on, what was then, UB23, at cruising altitude.
When would he have commenced the turn? Prior to or after overflying the VOR to stay on the airway centre-line?
Thank-you for any informative responses............

In the early 1980s, fly-over, then correct the overshoot outbound, was the norm; especially if an airplane did not have DME, and/or had only a single VOR receiver. These days RNAV is commonplace, so an early turn to remain on centerline is the norm.
RNAV waypoints are now generally understood to be "fly through" (early turn) unless specifically coded as "fly over" (on some SIDs & STARs, particularly).

The Vicenza 'Banger.'
Hmm, well I always knew when we were approaching Vicenza from the damn great cu-nimb permanently parked above it. Made the 'early turn' a non-decision.
