Narrative:

After receiving ground clearance from fpr, the instructions were after takeoff, follow runway heading until 2000 ft, and then turn to intersection bairn, then to ocala then to gnv, which would have required a heading of 290 degrees or 300 degrees, following the GPS. After reaching 4000 ft, told the mia controller that there are some heavy buildups and asked for course correction of at least 15-20 degrees, because I was heading for a large twring cumulus. It appeared at that time the mia controller was angrily arguing with several other aircraft in the general area. I was under the impression that I was given further instruction to deviate because of the cumulonimbus cloud, but after a short time, the controller asked me what heading and I told him, so he started on me this time, telling me that I should first check in with him. I had called him 3 times via 132.25 and assumed that he had heard me. After the controller corrected and advised me, in a very belligerent and demeaning way, that I check in before I turn again, he cleared on my heading. As I entered the cumulonimbus cloud, the airplane entered severe turbulence, which completely knocked out all of my instrumentation and electronics, losing all of my navigational equipment and instrument flight instruments. I was still on course, when the mia controller started on me again. I tried to re-explain to him, that I was still on course to the bairn intersection. This time, this controller was totally out of line, seeming to argue with every aircraft under his control in that area. I also heard this controller give an altitude clearance to another aircraft and then told this pilot that he hadn't given him. I know everyone has a certain amount of bad days, but this controller had really lost it that day. I feel that the controller was getting everyone mixed up with other aircraft flying in that area. I find it to be a lack of communication between the known aircraft in the local area. I find it very dangerous that an mia controller was totally out of control. He simply could have been more helpful that given day.

Title: C208 PLT INITIATED HEADING CHANGE DUE TO WX FROM ASSUMED DEV CLRNC OF MIA DEP CTLR ONLY TO BE THE RECIPIENT OF A CTLR LECTURE, FURTHER COMPLICATED BY FLYING INTO CUMULUS CLOUDS.

Narrative: AFTER RECEIVING GND CLRNC FROM FPR, THE INSTRUCTIONS WERE AFTER TKOF, FOLLOW RWY HEADING UNTIL 2000 FT, AND THEN TURN TO INTXN BAIRN, THEN TO OCALA THEN TO GNV, WHICH WOULD HAVE REQUIRED A HEADING OF 290 DEGS OR 300 DEGS, FOLLOWING THE GPS. AFTER REACHING 4000 FT, TOLD THE MIA CTLR THAT THERE ARE SOME HVY BUILDUPS AND ASKED FOR COURSE CORRECTION OF AT LEAST 15-20 DEGS, BECAUSE I WAS HEADING FOR A LARGE TWRING CUMULUS. IT APPEARED AT THAT TIME THE MIA CTLR WAS ANGRILY ARGUING WITH SEVERAL OTHER ACFT IN THE GENERAL AREA. I WAS UNDER THE IMPRESSION THAT I WAS GIVEN FURTHER INSTRUCTION TO DEVIATE BECAUSE OF THE CUMULONIMBUS CLOUD, BUT AFTER A SHORT TIME, THE CTLR ASKED ME WHAT HEADING AND I TOLD HIM, SO HE STARTED ON ME THIS TIME, TELLING ME THAT I SHOULD FIRST CHK IN WITH HIM. I HAD CALLED HIM 3 TIMES VIA 132.25 AND ASSUMED THAT HE HAD HEARD ME. AFTER THE CTLR CORRECTED AND ADVISED ME, IN A VERY BELLIGERENT AND DEMEANING WAY, THAT I CHK IN BEFORE I TURN AGAIN, HE CLRED ON MY HEADING. AS I ENTERED THE CUMULONIMBUS CLOUD, THE AIRPLANE ENTERED SEVERE TURB, WHICH COMPLETELY KNOCKED OUT ALL OF MY INSTRUMENTATION AND ELECTRONICS, LOSING ALL OF MY NAVIGATIONAL EQUIP AND INST FLT INSTS. I WAS STILL ON COURSE, WHEN THE MIA CTLR STARTED ON ME AGAIN. I TRIED TO RE-EXPLAIN TO HIM, THAT I WAS STILL ON COURSE TO THE BAIRN INTXN. THIS TIME, THIS CTLR WAS TOTALLY OUT OF LINE, SEEMING TO ARGUE WITH EVERY ACFT UNDER HIS CTL IN THAT AREA. I ALSO HEARD THIS CTLR GIVE AN ALT CLRNC TO ANOTHER ACFT AND THEN TOLD THIS PLT THAT HE HADN'T GIVEN HIM. I KNOW EVERYONE HAS A CERTAIN AMOUNT OF BAD DAYS, BUT THIS CTLR HAD REALLY LOST IT THAT DAY. I FEEL THAT THE CTLR WAS GETTING EVERYONE MIXED UP WITH OTHER ACFT FLYING IN THAT AREA. I FIND IT TO BE A LACK OF COM BTWN THE KNOWN ACFT IN THE LCL AREA. I FIND IT VERY DANGEROUS THAT AN MIA CTLR WAS TOTALLY OUT OF CTL. HE SIMPLY COULD HAVE BEEN MORE HELPFUL THAT GIVEN DAY.
