Narrative:

Shortly after level off at FL190 (intermediate altitude) and upon arriving at ZZZ VOR; aircraft experienced multiple failures: captain's flight director; first officer pitot heat; #1 pitch trim and FMS/navigation disengagement. As pilot not flying; captain analyzed and prioritized failures. Over this fix aircraft was supposed to turn toward our next fix. We had gone approximately 2 miles past the navigation turn point before the navigation mode failure was realized and turn was initiated. This also occurred coincident with a frequency change. Both controllers queried us as to our flight path and we responded that a turn was already in progress to both controllers. The only way I can think corrective action could've been initiated more quickly would have been to recognize navigation mode before disconnect. However; with no warning light associated with condition; I think that would be difficult under these circumstances.

Title: An A300 Captain's Flight Director; First Officer's Pitot Heat and #1 Pitch Trim failed in flight at the same time the FMS NAV disengaged. No annunciation or alert was given and the systems were returned to normal some time later.
