VOR approaches
Flying a course off a ground station with no vertical guidance -- an on-field VOR at Nantucket and an off-field VOR at Hyannis, both on real charts.

After this lesson you can
- Explain why a VOR approach is flown to an MDA rather than a DA, and what that means for how the descent is built.
- Describe the difference between an on-field VOR and an off-field VOR approach, and locate the final approach fix on each.
- Read the FAF-to-MAP timing table on a VOR chart and use it when no distance-measuring fix is available.
- Compare category minimums for a straight-in and a circling line on the same VOR chart.
The VOR approach is the ancestor of every non-precision approach in the system: a lateral course flown off a ground station, an altitude floor, and no vertical guidance at all. Everything the ILS did for you automatically -- telling you when to start down, how fast, and exactly when to decide -- the VOR approach leaves for the pilot to build.
That is what makes it a good teaching tool. This lesson works through two real VOR/DME approaches in southeastern New England: VOR RWY 24 into Nantucket (ACK), where the VOR sits right on the airport, and VOR RWY 6 into Hyannis (HYA), where the VOR is off the field at Martha's Vineyard and the whole approach structure is built from DME distances off it.
The rest of this lesson
- 1.A VOR approach in outline
- 2.MDA: a floor you level off at, not a point you decide at
- 3.When the VOR sits on the airport: VOR RWY 24, Nantucket
- 4.When the VOR sits off the field: VOR RWY 6, Hyannis
- 5.Timing the final segment without a distance fix
- 6.What the two charts teach side by side
These 6 sections, their figures, the checks along the way and the end-of-lesson quiz come with the IFR track. Paid once, yours for good.
