C172 INSTRUCTOR; WITH TRAINEE; PRACTICING NIGHT TKOFS AND LNDGS; WAS BOTHERED BY THE RWY LIGHTS' INTENSITY RAISED JUST PRIOR TO TKOF BY A BEECH 1900 FLC ON A 4 MI FINAL. THEY LOWERED THE LIGHT INTENSITY ONLY TO HAVE IT IMMEDIATELY RAISED BACK AGAIN.

Narrative

I WAS AN INSTRUCTOR ON A DUAL LCL TRAINING FLT AT THE AUG ARPT ON JUL/XA/01 AT XA30. MY STUDENT AND I HAD JUST MADE A LNDG ON RWY 35 IN A C172. AFTER LNDG; WE ANNOUNCED OUR BACK-TAXI AND PROCEEDED TO BACK-TAXI THE 3500 FT TO TKOF AGAIN. AS WE WERE TURNING AROUND TO BACK TAXI; A BEECH 1900 COMMUTER ANNOUNCED THEY WERE 13 MI OUT; MAKING A STRAIGHT-IN APCH TO RWY 35. (NOTE: AT 13 MI FROM THE ARPT; ON A VFR NIGHT; AT AN UNCTLED ARPT DOES NOT ALLOW OTHER ACTIVITIES TO GO ON UNTIL THE APCHING ACFT IS IN THE VICINITY OF THE TFC PATTERN.) JUST BEFORE WE TURNED AROUND TO TAKE OFF; I DID SEE THE LNDG LIGHT FOR THE BEECH 1900 AND IT APPEARED TO ME THAT HE WAS WELL BEYOND 5 MI OUT. WE HAD PLENTY OF TIME TO BACK-TAXI AND TO TAKE OFF. WHEN WE REACHED THE END OF THE RWY 35; WE TURNED AROUND AND THE STUDENT STARTED THE TKOF AND CALLED THAT WE WERE DEPARTING RWY 35. RIGHT AFTER THIS; THE BEECH 1900 MADE A CALL THAT THEY WERE ON A 4-MI FINAL FOR RWY 35. (DURING OUR LNDG; BACK-TAXI AND TKOF THE RWY LIGHTS WERE ON LOW.) AS WE WERE DEPARTING; THE BEECH 1900 TURNED THE RWY LIGHTS ON HIGH. I FOUND IT ODD THAT THIS WAS THE ONLY TIME; AT 4 MI OUT; THAT HE BROUGHT THE RWY LIGHTS UP TO HIGH; AS MOST PLTS USE HIGH TO HELP THEM FIND THE ARPT. AFTER THEY TURNED THE RWY LIGHTS UP TO HIGH; I IMMEDIATELY TURNED BACK TO LOW BECAUSE THE LIGHTS ON HIGH MADE IT DIFFICULT TO SEE THE RWY DURING MY DEP. THEY THEN TURNED THE LIGHTS BACK UP TO HIGH; AND I TURNED THEM BACK TO LOW AND MADE A RADIO ANNOUNCEMENT TO THEM THAT WE WERE STILL TAKING OFF AND AS SOON AS WE WERE OUT OF THE WAY THEY COULD HAVE THE LIGHTS. AGAIN; I FIND IT ODD THAT INSIDE OF 4 MI A PLT WOULD WANT HIGH RWY LIGHTS. I MENTION THIS BECAUSE THE WHOLE ACTIVITY IN MY OPINION WAS HARASSMENT TO ME. AS I DID MY CLBOUT AND TURNED DOWNWIND FOR RWY 35 AT ABOUT 1400 FT MSL; I COULD SEE THE BEECH 1900 JUST COMPLETING HIS LNDG ROLL AND START TO BACK-TAXI TO RWY 35. I FEEL THERE WAS ADEQUATE TIME FOR ME TO TKOF AND FOR HIM TO LAND; WITHOUT CAUSING ANY UNDO MANEUVERING OR CHANGE IN FLT PATH OR REDUCTION IN SPD OR DISRUPTING HIS VIEW AND ORIENTATION TO THE RWY. I REALIZE BY FARS THAT THE LNDG ACFT HAS THE RIGHT-OF-WAY OVER ACFT ON THE GND. I FELT THAT DURING THIS WHOLE PROC THAT MY DEP TOOK PLACE IN A LEGAL WAY AS HE WAS STILL AT 5 MI OR BETTER TO TAKE OFF. AS A SUGGESTION TO REMEDY THE PROB; I WOULD SUGGEST THAT COMMUTER ACFT APCHING AN ARPT SHOULD CONFORM TO THE TFC PATTERN AS OTHER ACFT DO.
