HARTFORD, Conn. -- United Technologies Corp.'s third-quarter earnings results, due out before the markets open on Tuesday, will likely reflect some weakness in the aerospace market, a segment on which the company recently made a big bet.

WHAT TO WATCH FOR: The conglomerate, based in Hartford, Conn., makes jet engines, elevators, residential and commercial heating and cooling equipment and other aerospace and building systems. During the quarter, it closed on its largest acquisition, the $18.4 billion purchase of aerospace supplier Goodrich Corp. in Charlotte, N.C.
