Assistant
Based on our previous conversation and my understanding of the knowledge you've shared with me, I'll respond to your query.

**UAVs (Unmanned Aerial Vehicles)**

UAVs, also known as drones or unmanned aircraft systems (UAS), are [[Remote Controlled Aircraft|remote controlled aircraft]] that operate without a human pilot on board. They can be used for various purposes, including:

* Surveillance and reconnaissance
* Military operations
* Agricultural monitoring
* Environmental monitoring
* Aerial photography and videography
* Package delivery

UAVs typically consist of an airframe, engine, propellers, sensors, and a control system. Some UAVs are controlled remotely by a human pilot, while others can fly autonomously using pre-programmed flight plans or GPS navigation.

If you'd like to know more about UAVs, feel free to ask!

(Note: I couldn't find any specific notes on UAVs in your existing knowledge, so I've provided general information. If you have any additional notes or details, please let me know!)
