Narrative:

We were on the ramms arrival to den with a crossing restr of 17000 ft at ramms. ATC gave us the restr late, and it required a descent rate of about 4000 FPM. Due to the excessive descent rate (normal is 2500-3000 FPM) I elected to set the local altimeter setting (30.34) at about 24000 ft to prevent the autoplt from capturing the wrong altitude. When we were about 22000 ft center told us to cross ramms at 280 KTS. I asked if he wanted the speed or altitude, he told me both. I advised him that we would be unable to do that. He told us to level at FL190 and turn right. I set in 19000 ft in the altitude alerter and the autoplt captured. I neglected to set 29.92 as the altimeter setting. A few moments later center asked us our altitude, we told him FL190. He told us we were 400 ft low. We then realized our error and reset the altimeter to 29.92 and climbed to FL190. I don't believe there was a conflict with any other aircraft. This incident was caused by lack of rest. Our company has been scheduling reduced rest overnights that are either preceded or followed by long duty days. Our overnight was less than 9 hours long and we were beginning a 12 hour duty day when this occurred. I feel that after a short layover there should be a maximum duty time of 8 hours that cannot be extended because of WX, maintenance, etc.

Original NASA ASRS Text

Title: A CL65 FLT CREW SETS LCL ALTIMETER SETTING FOR A CLRNC TO 17000 FT, BUT WHEN IS LATER GIVEN FL190, THE FLT CREW FAILED TO RESET THE ALTIMETER TO 29 PT 92 RESULTING IN AN ALT OVERSHOOT OF 400 FT.

Narrative: WE WERE ON THE RAMMS ARR TO DEN WITH A XING RESTR OF 17000 FT AT RAMMS. ATC GAVE US THE RESTR LATE, AND IT REQUIRED A DSCNT RATE OF ABOUT 4000 FPM. DUE TO THE EXCESSIVE DSCNT RATE (NORMAL IS 2500-3000 FPM) I ELECTED TO SET THE LCL ALTIMETER SETTING (30.34) AT ABOUT 24000 FT TO PREVENT THE AUTOPLT FROM CAPTURING THE WRONG ALT. WHEN WE WERE ABOUT 22000 FT CTR TOLD US TO CROSS RAMMS AT 280 KTS. I ASKED IF HE WANTED THE SPD OR ALT, HE TOLD ME BOTH. I ADVISED HIM THAT WE WOULD BE UNABLE TO DO THAT. HE TOLD US TO LEVEL AT FL190 AND TURN R. I SET IN 19000 FT IN THE ALT ALERTER AND THE AUTOPLT CAPTURED. I NEGLECTED TO SET 29.92 AS THE ALTIMETER SETTING. A FEW MOMENTS LATER CTR ASKED US OUR ALT, WE TOLD HIM FL190. HE TOLD US WE WERE 400 FT LOW. WE THEN REALIZED OUR ERROR AND RESET THE ALTIMETER TO 29.92 AND CLBED TO FL190. I DON'T BELIEVE THERE WAS A CONFLICT WITH ANY OTHER ACFT. THIS INCIDENT WAS CAUSED BY LACK OF REST. OUR COMPANY HAS BEEN SCHEDULING REDUCED REST OVERNIGHTS THAT ARE EITHER PRECEDED OR FOLLOWED BY LONG DUTY DAYS. OUR OVERNIGHT WAS LESS THAN 9 HRS LONG AND WE WERE BEGINNING A 12 HR DUTY DAY WHEN THIS OCCURRED. I FEEL THAT AFTER A SHORT LAYOVER THERE SHOULD BE A MAX DUTY TIME OF 8 HRS THAT CANNOT BE EXTENDED BECAUSE OF WX, MAINT, ETC.
