BE35 PLT ENTERED DWORLD TFR.

Narrative

WHILE ON A VFR PLEASURE FLT FROM SFB TO LAL; ENRTE AT 2500 FT. THIS ALT WAS CHOSEN DUE TO CEILING LIMITATIONS OF APPROX 3500 FT. INITIAL HEADING WAS 244 DEGS; AND DEPARTED SFB AIRSPACE. ENRTE; CONDITIONS WERE HAZY; BUT LEGAL VFR CONDITIONS. THE EVENT HAPPENED APPROX XA00 LCL TIME AND ACFT WAS HEADING DIRECTLY INTO THE SETTING SUN. ATC WAS BUSY AND COULD NOT ACCOMMODATE VFR ADVISORY REQUESTS. WHILE ENRTE; PIC NOTICED THAT HE WAS APCHING THE DISNEY COMPLEX; SW OF ORLANDO. PLT COULD NOT SEE GND FEATURES OF WDW COMPLEX UNTIL ALMOST OVER IT. ONCE PIC NOTICED THAT A POSSIBLE VIOLATION OF THE WDW TFR EXISTED; IMMEDIATE ACTION WAS TAKEN TO TURN NW AND CLB TO 3200 FT MSL. THE CONTRIBUTING FACTORS WERE HAZE; DUSK AND DAYLIGHT SETTINGS; A CEILING OF 3500 FT AND POOR LANDMARKS DEPICTING THE WDW TFR. ALSO CONTRIBUTING WAS THE FACT THAT THE SETTING SUN WAS DIRECTLY ALIGNED WITH THE RTE OF FLT; CAUSING DIFFICULTY DISCERNING GND FEATURES. DUE TO THE LOW ANGLE OF THE SUN; THE PIC WAS MORE CONCERNED ABOUT SPOTTING CONFLICTING TFC RATHER THAN LOOKING AT THE GND. IT IS ESTIMATED THAT THE TFR MAY HAVE BEEN VIOLATED BY LESS THAN 1/4 MI AND 500 FT VERT.
