The notes are "DME required." and "Radar required for procedure entry." The DME is used for defining the IAF SKOAL, the MKL 12 DME arc, OZZIE, MERSY WUTOT, the MAP, and the MAP hold. You wrote: "It says DME required at top for arrival or radar vectors." That is not correct. That means it can be used for identifying any fix based on DME or a DME arc. Again training and we need to do hold practice. A direct to IF or FAF will cause problems for the 430. I was surprised but that is a fact.Ī follow up question is if an approach is not cycling, how do you recover? For example if holding at IF (hold instead of procedure turn), the ONLY way to get out of the hold and start the approach is CLEAR the hold. They will tell you to switch to CTAF and call this Freq if you miss. They just don't have coverage that low to monitor your approach. How do I know? I visited ARTCC and talked to them and this topic came up. They can turn you yes, but can not clear you for approach, only help. Sure vectors are great, but my home base is 32NM from MEM ARTCC and MEM Approach. I fly for a living I am very familiar with vectors. I get different answers about the 430 automatically switching the Stby LOC Freq into active and going from GPS to VLOC mode automatically.Īs far as most pilots prefer vectors. So it is possible I should have left it alone and the waypoint would have cycled if I gave it time. Second is the cycling of waypoints in GARMIN. I am sure this is pretty universal, but does anyone know exceptions. Not withstanding the cycling issue and GARMIN note when you select it warning this is for reference only (not sure or recall exact verbiage). Keep in mind DME required comment in IAP plate. My question was is the DME OK for LOC approach with DME fixes. If I was training in LA airspace it would be with approach. We do file but I don't need or want to POP UP with Approach in VFR doing approaches to a rural area. I either give student ATC instructions (as ATC would and expect readback from student) or clear them for approach, monitoring ATC and CTAF. We did have good lesson on DME arc, timing, 5T's, missed and nice RNAV LPV to base airport (non towered VFR own Nav. We did an alternate missed and left the area back to base. Obviously ILS (with GS which we don't have) it would be DA for missed. I assume the GPS RWY Fix could be used for missed, but timing would be required here to be totally legit. The published missed can be flown by GPS (I assume) although holding fix is a radial and DME. There is a RWY FIX in the data base to trigger the missed. I know I visited the ARTCC and talked to them. I could go into detail but even our base a non towered airport with two RNAV approaches 30 NM from MEM ARTCC can not give vectors only advise. This is real world where radar is not available. We were VFR and talking to tower only no ATC vectors. We did the approached timed because that was the lesson. Since it was not cycling I ID'ed MERSY by map and instructed to 5T it (turn, time, transition, twist talk). OK I can not with standing the cycling issue. It says DME required at top for arrival or radar vectors. Doing LOC only (this plane has no GS receiver) with no DME (but GPS) can I use GPS, MERSY I-MKL 6.2DME. The limit on IAP says RADAR or DME required for arrival. Some other comments are not correct likely due to not understanding. So one things was auto switch to CDI which I thought had to be manual. The GNS430W gave turn guidance to start the ARC which was magenta. The other GA plane I fly has GTN750 with all the bells, whistles and options.Īpproach is loaded and activated. Also the RADAR required for procedure entry? īefore you all bash me all the planes I have flown recently have 2 DME, 2 GPS, LOC/GS/MB and 3 IRU's, all integrated into one FMS. GPS is not an acceptable substitute for DME on this Approach. Contacted KMKL tower about 5 miles from IAF SKOAL, start of 12 DME arc. So off we went VFR to to KMKL for the ILS or LOC 2 in VFR, student under hood. Keep in mind the plane has all the IFR requirements and current Garmin IFR database. My issue is the GPS did not cycle as expected from Arc to final approach segment. That is OK as the LPV counts as a precision approach for check. Only non GPS approaches it can do are VOR, having no GS receiver. All we had done were very basic or typical RNAV LPV approaches with HOLD entry. The KMKL LOC 02 was pretty much made to order. I wanted my student to do a LOC approach, as well as a DME arc, timed approach, and more complicated missed. However something happened with waypoint cycling on a DME arc to LOC approach. I am pretty proficient with the 430W, with RNAV approaches. In that time GNS430W came out 18 yrs ago. Been CFI-I-ME for 33 years but have not instructed much last 20 years. I am a CFI INST and have an Instrument student.
