Made my first VOR navigation flight from CYKF (Kitchener-Waterloo) to CYND (Ottawa-Gatineau) with the YellowBlue C172. Flight time was 1h49. My flight plan was as follows:
Take off from CYKF, join YMS R-30, join YSO R-90, continue past YSO and join VIE R-72, continue past VIE and join YOW R-76, join YOW R-85, land runway 9.
Nice pictures and flight! Regarding your question either or works. You can fly VFR using VOR’s and VFR altitudes or IFR using VORs, and IFR altitudes. So up to you!
