kaosfere 1 Posted June 7, 2014 Share Posted June 7, 2014 Hi! I bought GATC a while back and have been enjoying it, but I seem to have stumbled across a couple shortcomings in how it handles instrument approaches. Specifically, it seems as though DME arcs on an approach are treated as direct tracks, and RF turns are not handled at all. To give two examples, let's first look at the DME appoach to runway 35 at KOLM. (http://155.178.201.160/d-tpp/1406/00645VD35.PDF). With IAF of OZEYO, this is represented in the latest AIRAC as: APPTR,D35,35,OZEYO IF,OZEYO,46.776806,-123.140847, ,0.0,0.0,0,0,0,0,0,0,1,0, AF,JOGLU,46.725667,-122.997664,1,OLM,176.0,15.3,201.0,2,4200,0,0,0,0,1,0, If you attempt to fly this approach in GATC, however, it gets treated as though it were OZEYO DCT JOGLU, which leaves the flight at too large an angle to begin its final. For the second example, we can look at the RNAV-Z approach to runway 36 at KOMA. (http://155.178.201.160/d-tpp/1406/00304RRZ36.PDF) Coming from HORSS, which is listed as RF Required, this is in the data as: APPTR,R36-Z,36,HORSS IF,HORSS,41.254131,-96.058808, ,0.0,0.0,1,5000,0,0,0,0,1,0, TF,CRRZY,41.208731,-95.981036,0, ,0.0,0.0,0.0,0.0,2,3400,0,0,0,0,0,0,0.1 RF,ZIKEP,41.204372,-95.924872,1,CFBQN,29.0,2.4,2,2700,0,0,0,0,0,0,0.1 RF,LEAVS,41.240511,-95.894850,1,CFBQN,75.6,2.4,2,2000,0,0,0,0,0,0,0.1 If you fly this one in GATC, you will proceed directly from HORSS to CRRZY, but unlike with the DME arc approach, this one doesn't even show ZIKEP and LEAVS as waypoints; it's as though the simulator isn't bothering to parse those records. I know that RF turns are (relatively) new, but I would have thought that DME arcs would at least be supported properly. Or am I misunderstanding something?
