A Skywest Embraer ERJ-175 on behalf of United, registration N164SY performing flight OO-5585/UA-5585 from San Francisco,CA to Oklahoma City,OK (USA), was enroute at FL310 near the top of descent about 115nm west of Oklahoma City when the crew declared emergency reporting smoke in the cockpit. The aircraft rapidly descended to FL240 and FL230. Later on approach the approach controller queried whether they could see out of the window or whether they needed a SAR type approach, the crew responded they could see through the windows, it actually had been smoke in the cabin, it was only half so (illegible), they were still waiting for further information from the cabin crew. The aircraft continued to Oklahoma City for a safe landing on runway 35L about 28 minutes after leaving FL310.

The FAA reported: “SKYWEST AIRLINES FLIGHT 5585 REPORTED SMOKE IN THE COCKPIT, LANDED WITHOUT FURTHER INCIDENT”, unknown injuries, unknown damage, unknown tail number, unknown phase of flight.
