Let’s dissect this approach, RNAV 36 into Joplin and how it didn’t go very well for me. I was given that yesterday during a PnP flight. I think I did several items wrong which caused me to get way behind the aircraft and eventually go missed. Weather was 600 OVC and Mist, tops were about 4000. Aircraft is 55WB, C182/G and has a CNX80/GNS480 and coupled Autopilot. http://22.214.171.124/d-tpp/1711/00540R36.PDF I was approaching from the SE and was told by KC Center to expect this approach and “vectors to JEMLO for spacing” and for the RNAV 36 approach. I acknowledged that and got the approach loaded in the box. After some steering vectors I was cleared direct JEMLO and for the approach. At JEMLO is where I began the confusion chain... The 480 was indicating that the next item in the sequence was the procedure turn. But in “the rush” to do the approach I disconnected the AP and turned inbound to the runway. I was full on milk bottle at this time. But it between JEMLO and LOVRE, i never regained a stable approach. Twice while dealing with the GPS, I looked back to find myself in a 30-degree bank that I don’t remember inputting, and one of those looked a whole lot like an an unusual attitude setup from IFR training. After recovering from the last one, and 15 more seconds of not successfully regaining the needles (I only had an LNAV indication on the GPS), I called missed, climbed and went toward MITBY. I chose not to try again and first told ATC I was going to Fayetteville (my alternate) but then chose to just return home. Now for the self critique.. 1) while I have done lots of approaches in VFR and MVFR conditions, this was my first solo down to near minimums. So there was some apprehension and second guessing of ability. To fix this I plan to find a local CFII and try to get more approaches in actual conditions. Try to increase both proficiency and confidence. 2) not doing the procedure turn and uncoupling the AP was a bad decision. By accepting JEMLO at the start of the approach, the PT is the charted action and ATC should know this. So seeing me do that would be normal. Plus this would have allowed the AP to handle the lateral duties for the whole approach while I managed speed and altitude. And the 4nm back to JEMLO would be plenty of time to get settled and ready for the descent. My “shortcut” created unnecessary additional work because I got the GPS out of sequence, causing big distractions, which started the chain of becoming unstable and never heading straight on the approach course. To fix this: trust the system and don’t roll my own short cuts. Also remember to ask ATC questions when doubt about what they want me to do arises. Hindsight, I should asked for HOXER since I wasn’t that far and the angle of the heading would work. But if they insisted on JEMLO, the remind them I’ll be doing the PT as published. Questions and critical is welcome from the gallery.. point of this is for all to learn. And a question from me... for this approach, if I was due south of JEMLO and was given “cleared direct JEMLO and the RNAV36 approach”, because the start is JEMLO, I still execute the PT, correct?
