Narrative: Flying to IRESH; the FAF; we were visually fixated on a closed field (HLR) approximately 3 miles North of intended airport. Initially briefed a straight in ILS to Runway 01; but VFR traffic was landing Runway 19. Identified/discovered wrong airport overhead ILE. Distance on the MFD was not proportionate or representative of actual distance to ILE. Had to adjust pattern to land on intended runway (ILE) and subsequently overshot final; causing us to briefly fly into Gray AAF airspace. ILE is uncontrolled. Landing was uneventful.Increased vigilance for uncontrolled airports.


Second narrative: Since the wind was less than 10 knots we decided to use the calm wind runway number one. As we approached the area we noted KGRK. Looking further into distance we saw an airport and it was the only airport that showed up on our nearest airports on the MFD. It was located about where our airport was supposed to be we set up for the ILS one in the FMS. We proceeded to IRESH the final approach fix and announced our intentions on CTAF to land on Runway 1. And then we heard from traffic that they were landing on runway 19. This Airport has right traffic RW 1 one and left traffic for 19 thus keeping all the traffic on the south east side. Gray approach cleared as for the visual and we switched to Unicom. I announced we were going to do left traffic runway 19. We were at 2;500 feet with eyes on what we thought was the landing runway and had just started to descend down about 2;200 feet MSL I realized by looking at the MFD that we were over the top of the runway. We immediately climbed back to 2;500 feet. It was immediately evident that what we were looking at was not our airport. It was in fact KHLR. There was traffic in the left pattern for runway 19 on downwind; we made a left 270 and entered a right base. Then we made a short approach to runway 19 and landed at KILE. We may have entered Class D airspace of KGRK while making our left 270 back to Runway 19 at KILE. After landing [we] called GRAY Clearance delivery on 121.7 and cancelled IFR. Nothing was said. If I would have spent a little time reviewing the sectional I may have noticed the third airport and been looking for it during arrival. Fortunately we did have an approach in the box or else we probably would have landed at the wrong airport. I think this is a tricky place to fly into. Make a special note of the close proximity of Class D for KGRK as well as KHLR. Also; if a crew cancels IFR in the air and does a left pattern for 19 they are likely to penetrate KGRK Class D. KILE also has a flight school and if they are using 19 it poses an issue for jet traffic using 1.


Synopsis: A CE-560 flight crew reported an airspace violation when they had the wrong airport in sight during a visual approach to a non-towered airport.
