Narrative:

Departed mkc, cruised under kansas city class B airspace, left 2000 ft MSL to climb to 6500 ft. Started climb near inside edge of outside class B ring. The floor here is 4000 ft. I figured that my climb performance would not allow myself to violate (penetrate) the airspace or go above 4000 ft MSL before I was outside (horizontally) the class B airspace. When I obtained 6500 ft MSL, I noticed I was about 4 mi outside the class B airspace. I may have violated the airspace. Retrospectively, I would be more observant, figured in the headwind, and kept closer track of position.

Title: SMA PLT MAY HAVE INCURRED MKC CLASS B AIRSPACE.

Narrative: DEPARTED MKC, CRUISED UNDER KANSAS CITY CLASS B AIRSPACE, LEFT 2000 FT MSL TO CLB TO 6500 FT. STARTED CLB NEAR INSIDE EDGE OF OUTSIDE CLASS B RING. THE FLOOR HERE IS 4000 FT. I FIGURED THAT MY CLB PERFORMANCE WOULD NOT ALLOW MYSELF TO VIOLATE (PENETRATE) THE AIRSPACE OR GO ABOVE 4000 FT MSL BEFORE I WAS OUTSIDE (HORIZLY) THE CLASS B AIRSPACE. WHEN I OBTAINED 6500 FT MSL, I NOTICED I WAS ABOUT 4 MI OUTSIDE THE CLASS B AIRSPACE. I MAY HAVE VIOLATED THE AIRSPACE. RETROSPECTIVELY, I WOULD BE MORE OBSERVANT, FIGURED IN THE HEADWIND, AND KEPT CLOSER TRACK OF POS.
