Human Factors
During the arrival phase into PHX we were given the EAGUL 5 STAR. We were told to descend via and we had 4;000 set in the AAD which was the bottom at GIPSE. The descent was uneventful until we reached HOMRR at 16;000 MSL and our next crossing was at VNOMM between 11;000 MSL and 10;000 MSL. Given the fact that there is only 4.1 NM between HOMRR and VNOMM we were unable to make this crossing restriction and so advised ATC to which they responded okay and to continue descent. On the Garmin GTC it showed at VNOMM the 10;000 MSL was crossed out since the box realized we could not make it either. To me this is setting the crew up for failure and I do not recall during training how we handle this situation in advance to prevent an altitude deviation from occurring. I feel as though I am missing something on the STAR. However it seems as though this is the way it is printed and I do not see how anyone can make this restriction. I did not see any NOTAMs however I could very well have missed one. It did not seem as though ATC was concerned and we were under heavy workload at the time. I am hoping if there is a mistake in the printing on the chart this will help others.
