Procedure; Airport; Human Factors
We were on the VOR 34 into GKY. We were asked to report the FAF (BROUZ) inbound which we complied with. ATC asked; 'What are your intentions' after the missed. I returned with 'after the missed we would like to turn to the south west and hold at BROUZ' which is the published missed for that approach. ATC responded with 'roger'. We continued on the approach. About .5 NM out from the missed approach point he told us that there was an aircraft on departure just climbing out through our altitude southbound. I saw the aircraft and communicated such; as we continued to the MAP. The MAP for this approach is published as 13.1 DME from the TTT VOR. This has the aircraft directly over the Runway 34 threshold. As we were crossing the MAP we both immediately noticed another aircraft on rollout taking off Runway 16 opposing. At the same time the airplane on takeoff saw us and told Tower that there was a helicopter directly in his way. We took evasive action to the right as did the airplane. The Tower never told us to break off early. When he realized that he had a near miss; he told us he thought we were turning southwest before the missed approach point. I told him that I was going to go southwest after going missed. I said that the MAP is directly over the threshold for that approach. He stated that I must not be familiar with the procedure here that at Arlington they go missed early. We had no way of knowing this as we followed the published procedure to the letter and had announced to Tower that we were executing said procedure with no additional information from them. They never told us to break off early. ATC should not assume that a person knows about a local procedure. They need to give detailed instructions to break off early.
Helicopter pilot reports a NMAC at the MAP for the VOR Runway 34 approach to GKY; with an aircraft deaprting Runway 16. The Tower expected the Helicopter to go missed early but did not communicate that information.
