BVR stands for Beyond Visual Range, which is mostly used in military communication to describe detecting and engaging targets beyond the limit of visual identification. There are few synonyms for BVR such as OVR (Out of Visual Range), LR (Long Range), or ENGBR (Extended Non-Guided Beyond Range). These synonyms are used to describe the same situation where objects or targets are detected or engaged beyond visual range. In the aviation industry, BVR is replaced by NL (No Limits) or NFR (No Flight Restrictions) as aircraft are capable of traveling beyond visual range. Regardless of the specific term used, the concept remains the same- identifying and engaging objects at a distance beyond what can be seen with the human eye.
