Narrative:

We were clear of takeoff on runway 36 at dca, apparently we lost our instruments on takeoff HSI, ADI, and VHF navigation captain's and first officer's. These instruments are all in conjunction with the IRS system on the aircraft. We advised departure control of our situation. We were given turns until we could input a magnetic course from the compass into the FMC. Once the inputs were executed we had normal instrument and VHF navigation capability. Emphasis should be directed in training pertaining to human factors related to being dependent upon advanced/automated cockpits.

Title: HDG TRACK DEV BY DEP ACR MLG WHEN ACFT EQUIP PROBLEM OF LOSS OF FLT INSTS OCCURS ON TKOF.

Narrative: WE WERE CLR OF TKOF ON RWY 36 AT DCA, APPARENTLY WE LOST OUR INSTS ON TKOF HSI, ADI, AND VHF NAV CAPT'S AND FO'S. THESE INSTS ARE ALL IN CONJUNCTION WITH THE IRS SYS ON THE ACFT. WE ADVISED DEP CTL OF OUR SITUATION. WE WERE GIVEN TURNS UNTIL WE COULD INPUT A MAGNETIC COURSE FROM THE COMPASS INTO THE FMC. ONCE THE INPUTS WERE EXECUTED WE HAD NORMAL INST AND VHF NAV CAPABILITY. EMPHASIS SHOULD BE DIRECTED IN TRAINING PERTAINING TO HUMAN FACTORS RELATED TO BEING DEPENDENT UPON ADVANCED/AUTOMATED COCKPITS.
