Human Factors
I was the PM in the right seat. On short final on ILS 4R into BOS. The ceilings were at 1;200 feet. We had the runway in sight. We were over the extended threshold as the PF was aiming for the 1;000 feet runway markers when we got a EGPWS 'glide slope' at approximately 50 feet. I noticed at that time that the PAPI were indicating 3 red; at that time the PF said correcting and started to pitch up. Then we received 2 more 'glide slope' EGPWS. We continued to land the aircraft. We were over the runway. His descent below glide slope was not intentional.Suggestions - Be more vigilant in calling out the glide slope and PAPI deviations even in VMC conditions.
Air carrier Captain reported an unstabilized approach during final to BOS airport resulting in a CFTT event requiring crew pitch up correction.
