Aircraft
On departure after contacting Departure Control and given climb to 14;000 FT; flying an RNAV Departure in NAV we lost ATS and NAV. First Officer flying first noticed problem when he lost his course and pitch bars in his PFD. Concurrently I noticed the loss of the ATS with N1 exceeding Climb Thrust Limits on all three engines. Meanwhile First Officer called for flaps retract while I continued to troubleshoot. Soon after retracting flaps ATC gave us a left turn to 090 and level off at 6;000 FT. We then realized we had gone past a waypoint on the departure; which was why ATC gave us the vector and level off. We then informed ATC that we had lost our NAV and was having issues with other systems. Within a short period we regained all systems; retracted the slats and returned to normal procedures to continue on our way uneventfully to our filed destination. Communicate the NAV problem right away and ask for vectors.
A DC-10 on an RNAV departure climb lost both the autothrust and navigation capabilities for a short period time which caused a track deviation.
