Narrative:

During a training mission which included a part 135 sic chkride for 3 applicants (including myself), the aircraft apparently momentarily entered class C airspace without clearance. The sic checks were being conducted from jvy and included pattern work and instrument approachs at that airport. Jvy airport is located just north of the sdf class C airspace. During the flight sdf approach contacted the captain about the aircraft's flight path near or through their airspace. According to them and their radar, we were entering their class C during our climbing turnouts from takeoff/missed approachs. According to the sectional chart for the area, the class C airspace 10 mi ring overlies a divided highway at its northern boundary. We were taking care to keep our flight path north of that highway to avoid the class C. However, the traffic at jvy was heavy and several times we had to deviate for traffic clearance and may have extended too far south in the interest of traffic avoidance and flight safety. Due to the aircraft's speed we were further south than normal before being high enough to turn when these traffic problems were encountered. After the flight the captain spoke with the controllers via telephone and cleared up the whole matter. The controller mentioned the proposal for the redesign of sdf class C which would include a notch just south of jvy to help accommodate the increasing jet traffic at that airport when they are conducting VFR training and operations. In my opinion the redesign is very necessary and would easily solve these problems (which will only increase as jvy attracts more and more jet traffic as a reliever for the sdf area).

Original NASA ASRS Text

Title: DURING SIC TRAINING IN A LEAR LONGHORN, LR55, CLASS C AIRSPACE WAS INADVERTENTLY PENETRATED DURING CLBOUT AFTER TKOF DUE TO THE CLOSE PROX OF THE CLASS C OVERLYING AIRSPACE. FLC BELIEVED THAT THEY HAD AVOIDED PENETRATING THE AIRSPACE, BUT ATC ADVISED OTHERWISE.

Narrative: DURING A TRAINING MISSION WHICH INCLUDED A PART 135 SIC CHKRIDE FOR 3 APPLICANTS (INCLUDING MYSELF), THE ACFT APPARENTLY MOMENTARILY ENTERED CLASS C AIRSPACE WITHOUT CLRNC. THE SIC CHKS WERE BEING CONDUCTED FROM JVY AND INCLUDED PATTERN WORK AND INST APCHS AT THAT ARPT. JVY ARPT IS LOCATED JUST N OF THE SDF CLASS C AIRSPACE. DURING THE FLT SDF APCH CONTACTED THE CAPT ABOUT THE ACFT'S FLT PATH NEAR OR THROUGH THEIR AIRSPACE. ACCORDING TO THEM AND THEIR RADAR, WE WERE ENTERING THEIR CLASS C DURING OUR CLBING TURNOUTS FROM TKOF/MISSED APCHS. ACCORDING TO THE SECTIONAL CHART FOR THE AREA, THE CLASS C AIRSPACE 10 MI RING OVERLIES A DIVIDED HWY AT ITS NORTHERN BOUNDARY. WE WERE TAKING CARE TO KEEP OUR FLT PATH N OF THAT HWY TO AVOID THE CLASS C. HOWEVER, THE TFC AT JVY WAS HVY AND SEVERAL TIMES WE HAD TO DEVIATE FOR TFC CLRNC AND MAY HAVE EXTENDED TOO FAR S IN THE INTEREST OF TFC AVOIDANCE AND FLT SAFETY. DUE TO THE ACFT'S SPD WE WERE FURTHER S THAN NORMAL BEFORE BEING HIGH ENOUGH TO TURN WHEN THESE TFC PROBS WERE ENCOUNTERED. AFTER THE FLT THE CAPT SPOKE WITH THE CTLRS VIA TELEPHONE AND CLRED UP THE WHOLE MATTER. THE CTLR MENTIONED THE PROPOSAL FOR THE REDESIGN OF SDF CLASS C WHICH WOULD INCLUDE A NOTCH JUST S OF JVY TO HELP ACCOMMODATE THE INCREASING JET TFC AT THAT ARPT WHEN THEY ARE CONDUCTING VFR TRAINING AND OPS. IN MY OPINION THE REDESIGN IS VERY NECESSARY AND WOULD EASILY SOLVE THESE PROBS (WHICH WILL ONLY INCREASE AS JVY ATTRACTS MORE AND MORE JET TFC AS A RELIEVER FOR THE SDF AREA).

During sic training in a lear longhorn, LR55, class C airspace was inadvertently penetrated during climb out after takeoff due to the close proximity of the class C overlying airspace. Flight crew believed that they had avoided penetrating the airspace, but ATC advised otherwise.
