Narrative:

Mvd has a displaced threshold for runway 24. Upon back-taxiing down runway 6, there is a turn-button short of the displaced threshold to turn around. It was not yet quite dark and the runway lights were not on (including the red lights for the displaced threshold). I missed the turn button while looking at the turnaround point for the whole runway. The tower instructed us to hold our position and required a tow truck to repos us in the proper spot, as they would not allow us to continue to the normal spot. There was also confusion as to whether we should shut the engines down, as the tower aid we could leave them in idle, but at the time of repositioning, the airport auths required shutdown. The repositioning was made, engines restarted and uneventful takeoff made. They said it had happened several times before. I think one thing to prevent this would be to have the tower remind the pilots when they are back-taxiing that the first turnaround button must be used. Callback conversation with reporter revealed the following information: reporter revealed that it was indicated in the NOTAMS that aircraft are not to go to the end of the runway to make 180 degree turns. The turn button is supposed to be used. The reporter said that he forgot about it. The displaced threshold starts just east of the turn button which is about 1000 ft from the approach end of runway 24.

Title: A B767 FLT CREW HAVE TO SHUT DOWN THEIR ENGS AND BE TUGGED TO TURN 180 DEGS ON RWY 6 DUE TO THE ARPT NOT ALLOWING IT TO BE DONE UNDER ACFT PWR.

Narrative: MVD HAS A DISPLACED THRESHOLD FOR RWY 24. UPON BACK-TAXIING DOWN RWY 6, THERE IS A TURN-BUTTON SHORT OF THE DISPLACED THRESHOLD TO TURN AROUND. IT WAS NOT YET QUITE DARK AND THE RWY LIGHTS WERE NOT ON (INCLUDING THE RED LIGHTS FOR THE DISPLACED THRESHOLD). I MISSED THE TURN BUTTON WHILE LOOKING AT THE TURNAROUND POINT FOR THE WHOLE RWY. THE TWR INSTRUCTED US TO HOLD OUR POS AND REQUIRED A TOW TRUCK TO REPOS US IN THE PROPER SPOT, AS THEY WOULD NOT ALLOW US TO CONTINUE TO THE NORMAL SPOT. THERE WAS ALSO CONFUSION AS TO WHETHER WE SHOULD SHUT THE ENGS DOWN, AS THE TWR AID WE COULD LEAVE THEM IN IDLE, BUT AT THE TIME OF REPOSITIONING, THE ARPT AUTHS REQUIRED SHUTDOWN. THE REPOSITIONING WAS MADE, ENGS RESTARTED AND UNEVENTFUL TKOF MADE. THEY SAID IT HAD HAPPENED SEVERAL TIMES BEFORE. I THINK ONE THING TO PREVENT THIS WOULD BE TO HAVE THE TWR REMIND THE PLTS WHEN THEY ARE BACK-TAXIING THAT THE FIRST TURNAROUND BUTTON MUST BE USED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR REVEALED THAT IT WAS INDICATED IN THE NOTAMS THAT ACFT ARE NOT TO GO TO THE END OF THE RWY TO MAKE 180 DEG TURNS. THE TURN BUTTON IS SUPPOSED TO BE USED. THE RPTR SAID THAT HE FORGOT ABOUT IT. THE DISPLACED THRESHOLD STARTS JUST E OF THE TURN BUTTON WHICH IS ABOUT 1000 FT FROM THE APCH END OF RWY 24.
