Flight 193 operated as a scheduled passenger from Miami to Pensacola, FL, with en route stops at Melbourne and Tampa, New Orleans, Louisiana, and Mobile. About 21:02 CDT the flight departed Mobile on an IFR flight plan to Pensacola and climbed to the cruising altitude of 7,000 feet. At 21:09, the crew were told that they would be vectored for an airport surveillance radar (ASR) approach to runway 25. At 21:13, the radar controller told National 193 that it was 11 nm NW of the airport and cleared it to descend and maintain 1,700 feet. At 21:17 flaps were selected at 15° and two minutes later the flight was cleared to descend to 1,500 feet and shortly after that further down to the MDA (480 feet). As the aircraft rolled out on the final approach heading, the captain called for the landing gear and the landing final checklist.
