Narrative:

In the morning around XA45, my student and I were conducting a training flight. We had received a radio check from unicom and were finishing up our runup. We held short of runway 9 at greeley-weld airport. We heard no calls, nor did we see any traffic on final, base, or downwind. We did a final check of the runway and didn't see anyone on the runway. We held position on the runway for a final instrument check. (Runway 9 is a 5800 ft runway with a slight hump in the middle making it hard to see the other end of the runway.) we saw nobody. After takeoff, we were approximately 200 ft AGL when my student said 'look.' on the approach end of runway 27 was a king air just holding its position. I took the controls, sidestepped to the right and as I looked back, he turned on his landing light, and made a call on unicom that he was departing runway 27 wbound. I asked my student, and we both verified that we never heard a call from him back-taxiing or holding in position on runway 27. We had verified with our radio check earlier that our radios were working properly and we had made calls prior to, and while entering the runway for departure. We also heard him make the departure call, and turn on his landing light before takeoff after we departed. Being early morning, and kind of hazy down low, plus runway conditions (hump in the middle of the runway) could have prevented us from seeing the aircraft. But the king air wasn't on the ramp when we passed going to the runway 9 runup area, so I'm not sure how long he was sitting there. Also, if he heard us make a call to depart runway 9, why didn't he call and say he was on runway 27? He could have been off frequency and getting a clearance. I didn't get a chance to find this out from him, nor did he seem too interested in why I departed off of runway 9 with him on runway 27.

Title: C172 INSTRUCTOR OBSERVED A KING AIR HOLDING AT THE OPPOSITE END OF THE RWY ON WHICH HE AND HIS STUDENT HAD JUST TAKEN OFF AT UNCTLED GXY ARPT.

Narrative: IN THE MORNING AROUND XA45, MY STUDENT AND I WERE CONDUCTING A TRAINING FLT. WE HAD RECEIVED A RADIO CHK FROM UNICOM AND WERE FINISHING UP OUR RUNUP. WE HELD SHORT OF RWY 9 AT GREELEY-WELD ARPT. WE HEARD NO CALLS, NOR DID WE SEE ANY TFC ON FINAL, BASE, OR DOWNWIND. WE DID A FINAL CHK OF THE RWY AND DIDN'T SEE ANYONE ON THE RWY. WE HELD POS ON THE RWY FOR A FINAL INST CHK. (RWY 9 IS A 5800 FT RWY WITH A SLIGHT HUMP IN THE MIDDLE MAKING IT HARD TO SEE THE OTHER END OF THE RWY.) WE SAW NOBODY. AFTER TKOF, WE WERE APPROX 200 FT AGL WHEN MY STUDENT SAID 'LOOK.' ON THE APCH END OF RWY 27 WAS A KING AIR JUST HOLDING ITS POS. I TOOK THE CTLS, SIDESTEPPED TO THE R AND AS I LOOKED BACK, HE TURNED ON HIS LNDG LIGHT, AND MADE A CALL ON UNICOM THAT HE WAS DEPARTING RWY 27 WBOUND. I ASKED MY STUDENT, AND WE BOTH VERIFIED THAT WE NEVER HEARD A CALL FROM HIM BACK-TAXIING OR HOLDING IN POS ON RWY 27. WE HAD VERIFIED WITH OUR RADIO CHK EARLIER THAT OUR RADIOS WERE WORKING PROPERLY AND WE HAD MADE CALLS PRIOR TO, AND WHILE ENTERING THE RWY FOR DEP. WE ALSO HEARD HIM MAKE THE DEP CALL, AND TURN ON HIS LNDG LIGHT BEFORE TKOF AFTER WE DEPARTED. BEING EARLY MORNING, AND KIND OF HAZY DOWN LOW, PLUS RWY CONDITIONS (HUMP IN THE MIDDLE OF THE RWY) COULD HAVE PREVENTED US FROM SEEING THE ACFT. BUT THE KING AIR WASN'T ON THE RAMP WHEN WE PASSED GOING TO THE RWY 9 RUNUP AREA, SO I'M NOT SURE HOW LONG HE WAS SITTING THERE. ALSO, IF HE HEARD US MAKE A CALL TO DEPART RWY 9, WHY DIDN'T HE CALL AND SAY HE WAS ON RWY 27? HE COULD HAVE BEEN OFF FREQ AND GETTING A CLRNC. I DIDN'T GET A CHANCE TO FIND THIS OUT FROM HIM, NOR DID HE SEEM TOO INTERESTED IN WHY I DEPARTED OFF OF RWY 9 WITH HIM ON RWY 27.
