Narrative:

There have apparently been numerous recent changes in IFR routes, fixes, etc in the detroit area based largely on a new VORTAC in the area (113.4 MHZ). According to approach control, these changes are in the appropriate data bases and are on the new, current charts. But, somehow, they didn't show up on the nos charts. Nevertheless, ATC is issuing clrncs based on the new routes. There is no warning from ATC or via NOTAM that current legal nos charts are at least incomplete and perhaps inaccurate. I discovered this, as apparently others were doing, after I was cleared via a fix I couldn't find on my charts (crater intersection) while inbound to yip (willow run airport) from the west. My outbnd clearance several hours later was all via routes I could not identify, despite having current, legal charts. Radar vectoring can solve all these problems, if radio isn't lost. But the workloads for pilots and controllers both go way up. At the very least, a NOTAM alerting pilots to the nos chart problem (perhaps DOD charts, too) would prevent us from being caught by surprise (save a lot of air time with ATC trying to explain to everybody why they can't find their routes). Since I haven't seen the commercial charts, I can't be more specific as to how extensive the changes are or what dangers there might be to a nos chart user following now obsolete routes.

Title: PLT OF SMA WAS GIVEN A ROUTING INTO YIP VIA FIXES NOT ON HIS CHART.

Narrative: THERE HAVE APPARENTLY BEEN NUMEROUS RECENT CHANGES IN IFR ROUTES, FIXES, ETC IN THE DETROIT AREA BASED LARGELY ON A NEW VORTAC IN THE AREA (113.4 MHZ). ACCORDING TO APCH CTL, THESE CHANGES ARE IN THE APPROPRIATE DATA BASES AND ARE ON THE NEW, CURRENT CHARTS. BUT, SOMEHOW, THEY DIDN'T SHOW UP ON THE NOS CHARTS. NEVERTHELESS, ATC IS ISSUING CLRNCS BASED ON THE NEW ROUTES. THERE IS NO WARNING FROM ATC OR VIA NOTAM THAT CURRENT LEGAL NOS CHARTS ARE AT LEAST INCOMPLETE AND PERHAPS INACCURATE. I DISCOVERED THIS, AS APPARENTLY OTHERS WERE DOING, AFTER I WAS CLRED VIA A FIX I COULDN'T FIND ON MY CHARTS (CRATER INTXN) WHILE INBND TO YIP (WILLOW RUN ARPT) FROM THE W. MY OUTBND CLRNC SEVERAL HRS LATER WAS ALL VIA ROUTES I COULD NOT IDENTIFY, DESPITE HAVING CURRENT, LEGAL CHARTS. RADAR VECTORING CAN SOLVE ALL THESE PROBLEMS, IF RADIO ISN'T LOST. BUT THE WORKLOADS FOR PLTS AND CTLRS BOTH GO WAY UP. AT THE VERY LEAST, A NOTAM ALERTING PLTS TO THE NOS CHART PROBLEM (PERHAPS DOD CHARTS, TOO) WOULD PREVENT US FROM BEING CAUGHT BY SURPRISE (SAVE A LOT OF AIR TIME WITH ATC TRYING TO EXPLAIN TO EVERYBODY WHY THEY CAN'T FIND THEIR ROUTES). SINCE I HAVEN'T SEEN THE COMMERCIAL CHARTS, I CAN'T BE MORE SPECIFIC AS TO HOW EXTENSIVE THE CHANGES ARE OR WHAT DANGERS THERE MIGHT BE TO A NOS CHART USER FOLLOWING NOW OBSOLETE ROUTES.
