Narrative

WE WERE CLEARED TO LAND ON RWY 19. THE WIND WAS OUT OF 190 DEGS AT 7 OR 8 KTS. THE STUDENT WAS FLYING A LITTLE SLOWER THAN STANDARD AND LANDED SHORTER THAN STANDARD. I WAS ADVISING HIM BUT TOOK NO ACTION OTHER THAN COACHING BECAUSE EVERYTHING WAS WITHIN SAFE LIMITS. HE TOUCHED DOWN AND APPLIED LIGHT BRAKING AND I ADVISED HIM THAT HE DIDN'T NEED ANY BRAKING. THE LOCAL CTLR ASKED WHAT OUR DEST WAS ON THE ARPT. I RESPONDED THAT WE WANTED TO TAXI BACK AND DEPART EASTBOUND. THE CTLR TOLD US TO TURN L ON TXWY FOXTROT AND TAXI BACK TO RWY 19. TXWY FOXTROT HAS NO TXWY SIGNS VISIBLE FROM THE APCH END OF RWY 19. MY STUDENT TAXIED PAST FOXTROT AND WAS HEADED TO TURN L ON THE CROSSING RWY 25 WHICH WAS ACTIVE. I TOOK CTL AND EXECUTED A L APPROX 120 DEG TURN TO ENTER TXWY FOXTROT. THE CTLR; AS A PRECAUTION; CANCELED THE LNDG CLRNC FOR A JET ACFT LNDG ON RWY 25 AND FORCED HIM TO GO AROUND. IF THE STUDENT HAD BEEN FLYING SOLO; THERE COULD HAVE BEEN A PROBLEM. TXWY SIGNS SHOULD BE INSTALLED AT RWY 19 AND TXWY FOXTROT EVEN THOUGH IT IS VERY CLOSE TO THE APCH END OF RWY 19.
