Narrative

WE WERE FOLLOWING RADAR VECTORS TO FINAL COURSE FOR THE ILS RWY 26 APCH AT CHINO; CA. JUST BEFORE LOC INTERCEPTION; ONTARIO APCH TOLD US TO CONTACT CHINO TWR. WE COMPLIED. STUDENT HAD HSI SET TO PARADISE VOR; AND #2 NAV TO CHINO LOC. STUDENT WAS UNDER HOOD. STUDENT FAILED TO SET CHINO LOC IN NAV 1 HSI. AS A RESULT OF THIS ERROR; STUDENT MAKE A TURN IN WRONG DIRECTION; ATTEMPTING TO INTERCEPT A RADIAL FROM PARADISE VOR INSTEAD OF CHINO LOC. IN THE MEANTIME; WE HAD FLOWN THROUGH THE LOC COURSE. I WAS AWARE OF AND MONITORING THE SITUATION; AND ATTEMPTING TO MAKE THE STUDENT RECOGNIZE THE PROBLEM. I FINALLY TOOK THE CTLS AND TURNED ACFT BACK TO REINTERCEPT LOC. WE DID NOT STRAY MORE THAN HALF SCALE DEFLECTION FROM LOC COURSE. AS I BEGAN TURN BACK TO COURSE; CHINO TWR BECAME ALARMED AT OUR INITIAL INCORRECT INTERCEPT HDG; AND THAT WE HAD FLOWN THROUGH THE LOC COURSE CENTERLINE. THEY THEN GAVE US A HDG TO FLY; TOLD US TO BREAK OFF THE APCH; AND TO CONTACT ONTARIO APCH FOR FURTHER INSTRUCTIONS. BY THIS TIME I HAD ALREADY SET UP A REINTERCEPT COURSE; STILL WITHIN A HALF SCALE DEFLECTION OF COURSE NEEDLE. I CONTACTED ONTARIO APCH AND INFORMED THEM OF THAT FACT; AND THEY ASKED ME IF I WAS RECEIVING THE LOC SIGNAL. I AGAIN TOLD THEM THAT I WAS. APPARENTLY; THERE WAS SOME CLOSE PROX TFC THAT THEY WERE CONCERNED ABOUT. APCH VECTORED US AROUND AGAIN FOR THE ILS APCH; AND THE REST OF THE FLT WAS UNEVENTFUL.
