While on an ILS 4R into EWR; I was the Captain; pilot flying. The EWR weather was 800 broken with light rain. Right at the cloud base; I lost my flight director; ILS raw data (including standy att); and VNAV PDI info. First Officer instrumentation remained normal. I maintained attitude and broke out in a few seconds low and right of course. (We received a low altitude warning from ATC). We had a normal landing. I wrote up all unusual indications and did a follow up call to Maintenance Control the following day.
On the ILS to 4R EWR at about 900 feet the Captain stated he lost his flight director. I stated I still had mine and asked if he would like to transfer controls to me. He said no. At about 800 feet we started to break out intermittently and the ground was partially visible. I noticed we were getting low and stated we are 1.5 dots low at the same time ATC issued a low altitude alert. At that point I had the runway in sight and told ATC we had the runway. The Captain arrested the descent rate and we were back on the glidepath. I was outside the aircraft and thought the Captain was too but at about 600 feet we were right of course. I was looking out the window at the runway thinking we need to fly left but didn't translate that correctly and stated we are left of course instead of saying to fly left. This is the first point I realized the Captain wasn't outside the aircraft. At this point I pointed to the runway that was off to the left and the Captain corrected. We were on glideslope and within lateral limits at the 500 foot stability gate so I felt comfortable continuing the approach and landing. The landing was uneventful and in the touchdown zone.
Air carrier flight crew reported the Captain experienced loss of flight director and ILS on approach to EWR; resulting in a low altitude alert from ATC.
