Narrative:

I departed linden airport about XX30 pm local time. After 45 mins of sightseeing around raritan bay, the visibility dropped considerably and ground fog moved in over the local area in which I was flying. Realizing I would not make linden airport due to the prevailing conditions, I contacted ewr approach. They issued me a VOR/DME approach into linden, which I denied because I knew minimum descent altitude was approximately the ht of the now dense fog. I was then given vectors and was issued the ILS 4R into ewr. This approach was going fine. At the OM I was told to break off the approach and enter a right base for runway 11. A successful landing was properly executed. My reason for sending in this report is for 2 sits: I may have entered the class B airspace when ground contact was lost, prior to contacting ewr approach, and, after being issued an IFR clearance, I was asked what flight visibility was. At the time it was about 3 mi. After my response of 3 mi, I went IMC, but everything remained under full control. I neglected to tell approach I was IMC. P.south., WX was checked several times before the flight, but I neglected to file a flight plan. The fog was not due to move in until later that evening. Bad judgement on my behalf to takeoff in the first place was my first mistake.

Title: IMC IN VFR FLT AND UNAUTH PENETRATION OF AIRSPACE, PROX OF TCA.

Narrative: I DEPARTED LINDEN ARPT ABOUT XX30 PM LCL TIME. AFTER 45 MINS OF SIGHTSEEING AROUND RARITAN BAY, THE VISIBILITY DROPPED CONSIDERABLY AND GND FOG MOVED IN OVER THE LCL AREA IN WHICH I WAS FLYING. REALIZING I WOULD NOT MAKE LINDEN ARPT DUE TO THE PREVAILING CONDITIONS, I CONTACTED EWR APCH. THEY ISSUED ME A VOR/DME APCH INTO LINDEN, WHICH I DENIED BECAUSE I KNEW MINIMUM DSCNT ALT WAS APPROX THE HT OF THE NOW DENSE FOG. I WAS THEN GIVEN VECTORS AND WAS ISSUED THE ILS 4R INTO EWR. THIS APCH WAS GOING FINE. AT THE OM I WAS TOLD TO BREAK OFF THE APCH AND ENTER A R BASE FOR RWY 11. A SUCCESSFUL LNDG WAS PROPERLY EXECUTED. MY REASON FOR SENDING IN THIS RPT IS FOR 2 SITS: I MAY HAVE ENTERED THE CLASS B AIRSPACE WHEN GND CONTACT WAS LOST, PRIOR TO CONTACTING EWR APCH, AND, AFTER BEING ISSUED AN IFR CLRNC, I WAS ASKED WHAT FLT VISIBILITY WAS. AT THE TIME IT WAS ABOUT 3 MI. AFTER MY RESPONSE OF 3 MI, I WENT IMC, BUT EVERYTHING REMAINED UNDER FULL CTL. I NEGLECTED TO TELL APCH I WAS IMC. P.S., WX WAS CHKED SEVERAL TIMES BEFORE THE FLT, BUT I NEGLECTED TO FILE A FLT PLAN. THE FOG WAS NOT DUE TO MOVE IN UNTIL LATER THAT EVENING. BAD JUDGEMENT ON MY BEHALF TO TKOF IN THE FIRST PLACE WAS MY FIRST MISTAKE.
