Narrative:

Departed ankeny airport (ikv), ia, approximately XX15. Climbing to an altitude of 17500 ft MSL, ikv direct altitude to land at clayton county tara airport, atlanta, GA. Made the comment to the person sitting in the right seat (who also is a pilot) we should have a nice flight with 60 KT tailwind, and the only thing to watch for is a restr area at fort campbell, clarksville, tn. As we approached the ckv the GPS alerted me that the fort campbell restr area was ahead. I put #1 VOR on ckv along with the DME. The plan was to cross the 0 degree radial of ckv 4 mi north. The restr area I would be close to would be 3701A, which tops out at 5000 ft MSL. All this time the GPS was showing me to be out of the other restr areas, including 3701A. In retrospect, I should have called fort campbell approach and had them radar vector me around the areas (as I did on the return trip). I have been flying professionally and pvtly for over 40 yrs and am well aware of restr areas. If by chance I did penetrate the restr area in question, whoever it may concern has my sincere apologies for any inconvenience I may have caused. In summary: 1) I have since flight-tested the GPS (northstar M-2B GPS/LORAN), the DME (king KN62) and the navigation (collin 351) and all are well within tolerance. 2) I will contact the appropriate ctrs, approach controllers or FSS regarding any future restr areas. 3) again, my apologies for any inconvenience I may have caused regarding this matter.

Title: PLT OF AN SMT TWIN INADVERTENTLY PENETRATED A RESTR AIRSPACE DURING A XCOUNTRY FLT TRANSITING THE AIRSPACE NEARBY.

Narrative: DEPARTED ANKENY ARPT (IKV), IA, APPROX XX15. CLBING TO AN ALT OF 17500 FT MSL, IKV DIRECT ALT TO LAND AT CLAYTON COUNTY TARA ARPT, ATLANTA, GA. MADE THE COMMENT TO THE PERSON SITTING IN THE R SEAT (WHO ALSO IS A PLT) WE SHOULD HAVE A NICE FLT WITH 60 KT TAILWIND, AND THE ONLY THING TO WATCH FOR IS A RESTR AREA AT FORT CAMPBELL, CLARKSVILLE, TN. AS WE APCHED THE CKV THE GPS ALERTED ME THAT THE FORT CAMPBELL RESTR AREA WAS AHEAD. I PUT #1 VOR ON CKV ALONG WITH THE DME. THE PLAN WAS TO CROSS THE 0 DEG RADIAL OF CKV 4 MI N. THE RESTR AREA I WOULD BE CLOSE TO WOULD BE 3701A, WHICH TOPS OUT AT 5000 FT MSL. ALL THIS TIME THE GPS WAS SHOWING ME TO BE OUT OF THE OTHER RESTR AREAS, INCLUDING 3701A. IN RETROSPECT, I SHOULD HAVE CALLED FORT CAMPBELL APCH AND HAD THEM RADAR VECTOR ME AROUND THE AREAS (AS I DID ON THE RETURN TRIP). I HAVE BEEN FLYING PROFESSIONALLY AND PVTLY FOR OVER 40 YRS AND AM WELL AWARE OF RESTR AREAS. IF BY CHANCE I DID PENETRATE THE RESTR AREA IN QUESTION, WHOEVER IT MAY CONCERN HAS MY SINCERE APOLOGIES FOR ANY INCONVENIENCE I MAY HAVE CAUSED. IN SUMMARY: 1) I HAVE SINCE FLT-TESTED THE GPS (NORTHSTAR M-2B GPS/LORAN), THE DME (KING KN62) AND THE NAV (COLLIN 351) AND ALL ARE WELL WITHIN TOLERANCE. 2) I WILL CONTACT THE APPROPRIATE CTRS, APCH CTLRS OR FSS REGARDING ANY FUTURE RESTR AREAS. 3) AGAIN, MY APOLOGIES FOR ANY INCONVENIENCE I MAY HAVE CAUSED REGARDING THIS MATTER.
