I-07: Non-precision approaches (VOR)

Recommended aircraft: fast piston (Beech Baron, Piper Seneca) , slow piston (Cessna Skyhawk, Piper Warrior)

Pilot will fly IFR from KSNA to KAVX and shoot the VOR/DME-B approach from the Santa Catalina (SXC) VOR, filing SLI V21 SXC for the route.

The approach does not dictate the runway that is used for landing. The circling prohibition simply means that the terrain obstruction that you would normally be afforded while circling at the prescribed altitudes/distances (varies with speed) turns into a pumpkin if you opt to position yourself SE of the field. Whether you opt to make a straight-in, or circle north of the field is up to you, for either runway.

Do NOT feel obliged to fly a regular traffic pattern if you are shooting the approach for real (ie, not in VFR conditions). Simply maneuver your plane to align yourself with the runway as needed.

The Instrument Flying Handbook has some good circling depictions. I'll try to post it as a reference on the site when I can, it's something I've been meaning to do.

does the circling SE of the runway prohibition require only a straight-in approach for rwy 22 which would be a right downwind? ie. no regular left pattern downwind and base leg would work as it would be SE of the rwy. Or is landing only on rwy 04 allowed? thnks

There is no published way to 'turn around' to get back to SXC to start the approach. The prohibition on circling SE of the field applies to the circling portion of the approach, conducted at the MDA after the FAF, you can ignore it prior to that point.

The reason that we typically vector off the airway is to get you pointed at SXC from somewhere south of SXC, to avoid this issue of how to turn around.

Had you been flying this under your own navigation, your method seems like it would be reasonable.

When I flew this qualification I was vectored to a point a few miles east of SXC, and then cleared for the VOR approach. My question is, if I had been flying own navigation I would have flying down the V-22. I had planned to cross over SXC and then make a 45 right/225 left course reversal, pass back over SXC (keeping west of the SXC R195), then proceed outbound on the SXC 352 and complete the approach as published. Would this have been right way to fly it? I was especially mindful that circling SE of runway 4/22 is prohibited.

Rwy 22 @ AVX uses something you may not have seen before flying here--a pulsating VASI, as opposed to the more common PAPI or standard VASI.

Pulsing white = well above glide slope
Solid white = on glide slope
Solid red = below glide slope
Pulsing red = well below glide slope
