FAR PT 135.219 a. "STRAIGHT-IN LANDING MINS. A STATEMENT OF MDA AND VISIBILITY, OR DH AND VISIBILITY..."
SENARIO: YOU ARE PLANNING AN IFR FLIGHT FROM APT "A" TO APT "B".
APT "A" IS 10000 SCT, CALM WINDS, APT ELEV 4200'. APT "B" ASOS IS REPORTING 4 HUNDRED OVERCAST 4 MILES VISIBILITY, CALM WINDS.
MY APPROACH IS A NON-PRECISION GPS. INTO APT "B" ELEV. 4155' MDA 5220-1 1/2
IS THAT WORD "STATEMENT". IN THE DEFENITION, SAYING I ONLY NEED THE NUMBERS PRINTED ON THE APPROACH PLATE IE. 5220-1 1/2 TO DEPART?
SOME SAY VISIBILITY IS CONTROLLING. I HAVE THE VISIBILITY REQUIREMENTS SO I CAN LEGALLY LAUNCH. KNOWING FULL WELL I WILL NOT BE ABLE TO SEE THRU CLOUDS 1065' THICK, AT THE MDA, IN THE DAYTIME.
IS IT LEGAL TO DEPART IFR?
PLEASE BACK UP ANY ANSWERS WITH A REFERENCE.
THANK YOU

As with all 135 rules there is "Pre-Flight planning rules" and then actual "In-flight rules". 135.219 is the former thereby requiring both ceiling and visibility requirements to be met "prior" to dispatch. Once in flight as you have already learned "visibility" is controlling and ceiling becomes irrelevant. You have to divide the 135 weather requirements into the two camps of "Pre-flight" and "in-flight". One has nothing to do with the other which makes it easier to understand.
Hope that helps.
