In a class D tower, is radar wake turbulence separation applicable between a larger VFR a/c followed by a smaller IFR a/c on final? Why or why not. Spoiler: Answer from the FAA the short answer is aircraft would not receive radar separation from the VFR tower, in accordance with 5-5-4. Chapter 5 is radar separation and VFR tower controllers are normally not operating under Chapter 5, Radar. However, wake turbulence procedures still apply in accordance with 2-2-19&20 and 3-10-3, which are advisory in nature. The inbound IFR would receive the approach clearance from radar approach control and communication would be transferred to the tower (typically, at least 7 to 10 miles out). Radar Approach may not even know what type aircraft is in the VFR pattern. Either way, the requirement would be for the tower to ensure Wake Turbulence advisories with the VFR aircraft.
