We were on the approach to LGA ILS04. We got vectored onto the loc and began our descent. I began a quick descent so I wouldn't be too high and stayed below the glide slope on the approach; which is the reason it never captured. After descending through the FAF we broke out of the clouds but got a 'glide slope' warning twice. The autopilot was disconnected and the plane leveled off. Shortly after ATC gave us a 'low altitude alert'. The approach was continued visually and we landed. Cause: When we got vectored we were at 7000' and needed to descend to 2700 per the approach. I felt as though I was being brought in high so I began a quick descent and stayed below the glide slope; which is the reason it never captured and initially caused confusion. Because of this I stayed in vertical mode during the descent which was too high for the approach and caused us to get a 'glide slope' warning. We were clear of the clouds and had the runway in site and decided to land. Suggestions: We should have been more aware of our altitude and descent rate on the approach. We should have completed a go around upon getting the glide slope warning as well as the low altitude alert from ATC.
We were on an ILS approach in LGA; and we were low on the approach which is why the glide slope never captured. We then got the runway in sight; and then heard 'glide slope' 'glide slope'. We disconnected the autopilot and leveled off. ATC then advised us that we were low when we had already correctedCause: We didn't want to be high on the approach which is why the glide slope never captured. The plane then would have just stayed in vertical mode instead of following the glide path downSuggestions: When we initially realized that we were unstable; we should have gone around and tried the approach again.
EMB-140 fight crew reported flying an unstable approach which resulted an EGPWS and ATC low altitude alert.
