Narrative:

Just past benky on bdf arrival, approach instructed, 'descend from 11000 to 7000 ft. ATC asked what our altitude was. I responded 11000 ft. He said he showed us off 400 ft. I realized I did not reset my altimeter setting to the local setting. I advised ATC my setting incorrect and reset. No further incident. My fault in I did not complete the altimeter setting procedure. Callback conversation with reporter revealed the following information: the approach briefing and coordination with the local station were noted as distrs that caused the oversight. It was noted that the altimeter setting is included on the descent checklist.
