However, when the pilot is using the JHMCS, the pilot can use the helmet-mounted display to cue the missile towards a specific target, regardless of whether it is within the radar's FOV or not. If a target is outside of this 60-degree, the missile may not be able to detect it using its own radar in BORE mode. This means that the radar can scan an area up to 60 degrees to the left or right of the missile's nose. The AIM-120C missile's radar has a field of view (FOV) of approximately 60 degrees on either side of the missile's centerline. In both modes, the pilot can use JHMCS to cue the missile towards a specific target, but in SLAVE mode, the external radar system provides more accurate guidance signals to the missile. The main difference between BORE and SLAVE guidance modes when using JHMCS with the AIM-120C missile is the source of guidance information.

However, in SLAVE mode, the external radar system provides more accurate guidance signals to the missile, allowing for more precise targeting. When using JHMCS, the pilot can use the helmet-mounted display to cue the missile towards a specific target just like in BORE mode. In SLAVE mode, the missile is guided by an external radar system, such as the radar on the launching aircraft or a ground-based radar system. The pilot can designate a target by looking at it through the helmet-mounted display, and the missile's guidance system will direct it towards the designated target. However, when using JHMCS, the pilot can use the helmet-mounted display to cue the missile towards a specific target. In BORE mode, the missile uses its own radar to search for and track the target. When using JHMCS with the AIM-120C missile, there are some differences between the BORE and SLAVE guidance modes. BORE mode is more autonomous and can be used in situations where the launching aircraft is not able to provide guidance, while SLAVE mode provides more accurate guidance and can be used in situations where the launching aircraft has a more advanced radar system. In BORE mode, the missile uses its own radar to search for and track the target, while in SLAVE mode, the missile relies on an external radar system to guide it towards the target. The main difference between BORE and SLAVE mode is the source of guidance information. The external radar tracks the target and sends guidance signals to the missile, which adjusts its course accordingly. Once the target is acquired, the missile's guidance system directs it towards the target. The missile is launched and guided towards the general direction of the target, and the missile's onboard radar scans the area to detect the target.

I studied about guidance modes of the AMRAAM and also with conjunction with JHMCS a bit more, here it is: Using Aim-120s in dogfights has potential for becoming a guilty pleasure. But I think the missile goes active almost instantly, and Ive never heard the JHMCS can actually cue a Maddog? I mean, that could be pretty funny, like an overly expensive cheap Aim-9x. Maddog just happens when you shoot the missile without a lock. To me using the missile radar directly seems more like something youd do at most when the FCR is damaged. If its missile radar is used, then it creates an RWR contact anyway? If anything the FCR might be faster at locking and providing a good solution to the Aim-120? I also dont really understand the point of just using Aim-120 for a lock before or instantly on firing. Both Aim-120 and Aim-9x are slaved to the FCR target (after lock). Under normal circumstances the boresight radar (dogfight mode, TMS up or so), definitely controls and locks the FCR, regardless of weapon equipped. The way I understand things is(someone please correct if otherwise):
