Certainly a puzzle. As I understand it a 'straight-in' has to be within 30 deg of the c/line, anyhting else would be a CTL, and in fact CTL is the only minima published (2450/70) for the VOR 21 - so why not call it a CTL R21? The 'VOR21' page also shows a profile descent BELOW CTL minima on the procedure.to a MAP at around 600'
.Also the new VOR 21 approach page does not really mesh with 10.0 and its guidance on flying the 'VOR21' below MDA.
I suspect someone in GCRR or Jepp has got confused! BTW, there is nothing in my book preventing a visual approach as long as you are visual by CTL minima. Why not raise it with your company?
