Unmanned aerial vehicle (UAV)-enabled integrated sensing and communication (ISAC) has attracted growing research interests towards sixth-generation (6G) wireless networks, in which UAVs are exploited as aerial wireless platforms to provide better coverage and enhanced sensing and communication (S\&C) services. However, due to the UAVs' size, weight, and power (SWAP) constraints, controllable mobility, and strong line-of-sight (LoS) air-ground channels, the UAV-enabled ISAC introduces both new opportunities and challenges. This article provides an overview on UAV-enabled ISAC, by presenting various solutions for optimizing the S\&C performance. In particular, we first present the UAV-enabled joint sensing and communication, and discuss the UAV maneuver control, wireless resource allocation, and interference management in the cases with single and multiple UAVs. Then, we present two application scenarios to exploit the mutual assistance between S\&C, namely sensing-assisted UAV communication and communication-assisted UAV sensing. Finally, we highlight several interesting research directions to motivate future work.
