C182 IN TFC PATTERN AT ISM EXPRESSED CONCERN REGARDING POSSIBLE AIRSPACE INTRUSION WHEN TWR ISSUED SEQUENCE SPACING TURNS.

Narrative

THIS FLT WAS MADE WITH 2 STUDENTS OF MINE WHO I HAD NOT FLOWN WITH FOR APPROX 6 MONTHS. THE PURPOSE WAS FOR THEM TO SHOW ME THE GLASS PANEL IN THEIR NEW C182. BECAUSE I WAS UNFAMILIAR WITH THE PANEL; I DID NOT CLASSIFY THIS A DUAL INSTRUCTION; WHICH I WAS GIVING TO THEM; BUT I WAS UNSURE HOW THE FAA WOULD CLASSIFY IT. KISSIMMEE TWR REQUESTED THAT WE ENTER A L DOWNWIND FOR RWY 24 AND RPT MIDFIELD DOWNWIND. WHEN WE DID SO HE INFORMED US THAT A LEARJET WAS ENTERING THE R BASE AND WE WOULD BE #2 TO LAND. HE ALSO REQUESTED THAT WE EXTEND OUR DOWNWIND TO ACCOMMODATE. WE DID SO AND IN A FEW SECONDS LATER AN MU2 RPTED HE WAS ON A VISUAL APCH AND R BASE FOR RWY 24. I RPTED THE LEARJET IN SIGHT AND STATED THAT I WAS STARTING A TURN TO L BASE. THE CTLR REPLIED THAT HE HAD CHANGED THE SEQUENCE AND THAT WE WOULD NOW BE #3 BEHIND THE MU2. THIS XMISSION WAS PERHAPS STEPPED ON OR NEVER MADE BECAUSE WE NEVER HEARD THE XMISSION AND I STATED SO TO THE TWR CTLR. HE ASKED US TO MAKE A R 270 DEG TURN FROM THE R BASE TO REJOIN THE FINAL FOR RWY 24. WE DID THIS WHICH PUT US RIGHT ON THE EASTERN EDGE OF KISSIMMEE CLASS D AIRSPACE AND ORLANDO CLASS B FOR A MATTER OF A FEW SECONDS. AFTER COMPLETING THE TURN AND REJOINING THE FINAL APCH; WE LANDED WITHOUT INCIDENT AND THE CTLR THANKED US FOR OUR HELP AND TOLD US TO CONTACT GND. AFTER THIS SCENARIO ANY ACFT ON L DOWNWIND/BASE/FINAL ARE GENERALLY SENT IN VARYING DIRECTIONS CREATING AN OFTEN CONFUSING SCENARIO. THIS IS ESPECIALLY SO WHEN RWY 24 IS IN USE BECAUSE OF ITS PROX TO ORLANDO INTL AND THE CLASS B ASSOCIATED.
