Narrative:

On departure from orl, runway 7, I flew north of highway depicted on TCA map, to stay clear of mco class B, at an altitude of 1200 ft MSL. There are 2 parallel hwys, 1 on the north border of sfc- 7000 class B space. On departure, I had crossed south of the northernmost highway, and flew 3/4 mi north of the southern highway. When the highway turned due north, I realized I was between the 2 hwys and not north of both. I immediately turned north. Upon careful study of the TCA chart, I estimate I was 1/8 mi south of the north limit first officer sfc-7000 class B airspace, traveling parallel to that limit, for approximately 3 mi. I was monitoring orl CTAF, tower was closed.

Title: SMA MISTAKES HWY AND ENTERS CLASS B AIRSPACE WITHOUT CLRNC.

Narrative: ON DEP FROM ORL, RWY 7, I FLEW N OF HWY DEPICTED ON TCA MAP, TO STAY CLR OF MCO CLASS B, AT AN ALT OF 1200 FT MSL. THERE ARE 2 PARALLEL HWYS, 1 ON THE N BORDER OF SFC- 7000 CLASS B SPACE. ON DEP, I HAD CROSSED S OF THE NORTHERNMOST HWY, AND FLEW 3/4 MI N OF THE SOUTHERN HWY. WHEN THE HWY TURNED DUE N, I REALIZED I WAS BTWN THE 2 HWYS AND NOT N OF BOTH. I IMMEDIATELY TURNED N. UPON CAREFUL STUDY OF THE TCA CHART, I ESTIMATE I WAS 1/8 MI S OF THE N LIMIT FO SFC-7000 CLASS B AIRSPACE, TRAVELING PARALLEL TO THAT LIMIT, FOR APPROX 3 MI. I WAS MONITORING ORL CTAF, TWR WAS CLOSED.
