## Discrepancy

DURING FLIGHT, ENGINE INDICATORS ON THE MFD HAD DROPPED TO ZERO AND RED X'D. CYCLED CIRCUIT BREAKERS, AND RESTARTED OUR AVIONICS BUSSES, BUT ISSUE PERSISTED. CAME BACK TO KBKX FOR A PRECAUTIONARY LANDING AND UPON TOUCHDOWN THE GUAGES CAME BACK. RAN THROUGH SOME TROUBLESHOOTING ON THE GROUND BUT WAS UNABLE TO RECREATE THE ISSUE. TOOK OFF AFTER ABOUT TEN MINUTES OF TRYING TO RECREATE THE PROBLEM. AIRPLANE GUAGES FLASHED FOR A SPLIT SECOND WITH RED X'S BUT OTHERWISE REMAINED OPERATIONAL WITH NO FURTHER ISSUES FOR REMAINDER OF THE FLIGHT.
