Narrative:

After vectors for spacing we were given a heading to intercept ogd 302 resume bearr 1 to kslc. We thought we were given 12000 ft but we were actually given 15000 ft at bearr intersection. We may even have read back 15000 ft but we put 12000 ft in the altitude alert. I was with a new first officer and while I was talking with ATC and looking at the chart, he put in 12000 ft and he started talking about how that was going to be a tough altitude to make at the 250 KT speed restr we had. Mistake #1 was overlooking his putting the altitude in the altitude selector. That is the PNF job. The altitude is then confirmed by the PNF. Mistake #2 was not questioning ATC about a restr that was almost impossible to make. That would also have clarified the altitude. They seldom give us an altitude that is that difficult to make without comment. The WX was VFR, we saw no traffic, had TCASII on 15 NM below and was showing no traffic. Mistake #3 was getting busy with making the incorrect crossing altitude and not checking.

Title: ALT DEV ON DSCNT. FLC ATC MISCOM. XING RESTR NOT MET.

Narrative: AFTER VECTORS FOR SPACING WE WERE GIVEN A HDG TO INTERCEPT OGD 302 RESUME BEARR 1 TO KSLC. WE THOUGHT WE WERE GIVEN 12000 FT BUT WE WERE ACTUALLY GIVEN 15000 FT AT BEARR INTXN. WE MAY EVEN HAVE READ BACK 15000 FT BUT WE PUT 12000 FT IN THE ALT ALERT. I WAS WITH A NEW FO AND WHILE I WAS TALKING WITH ATC AND LOOKING AT THE CHART, HE PUT IN 12000 FT AND HE STARTED TALKING ABOUT HOW THAT WAS GOING TO BE A TOUGH ALT TO MAKE AT THE 250 KT SPD RESTR WE HAD. MISTAKE #1 WAS OVERLOOKING HIS PUTTING THE ALT IN THE ALT SELECTOR. THAT IS THE PNF JOB. THE ALT IS THEN CONFIRMED BY THE PNF. MISTAKE #2 WAS NOT QUESTIONING ATC ABOUT A RESTR THAT WAS ALMOST IMPOSSIBLE TO MAKE. THAT WOULD ALSO HAVE CLARIFIED THE ALT. THEY SELDOM GIVE US AN ALT THAT IS THAT DIFFICULT TO MAKE WITHOUT COMMENT. THE WX WAS VFR, WE SAW NO TFC, HAD TCASII ON 15 NM BELOW AND WAS SHOWING NO TFC. MISTAKE #3 WAS GETTING BUSY WITH MAKING THE INCORRECT XING ALT AND NOT CHKING.
