AIM-120 CTRL page question
-
There is an option “ID” and it can be change to 1,2,3,4.
What is it ?
-
your position in the flight
1 for lead
2 for wingman
3 for element lead
4 for wingman -
@Red:
your position in the flight
1 for lead
2 for wingman
3 for element lead
4 for wingmanIs it effects the missile operation ?
-
Nope.

Thanks guys

From the T.O. BMS1F-16CM**-1** on page 85:
_When the A-A CNTL page is selected OSB #5 CNTL is
highlighted.There is not much to set here, except perhaps the MSL ID which
should match your flight # ID. It is good practice to set your MSL
ID to #2 for instance if you fly as wingman in a two ship.
This would serve the FCR datalink should it be implemented one
day. For the moment it is not implemented in BMS._ -
not modeled.
its the Missile Sequence ID number. Strictly speaking it doesn’t always correspond to flight position (157FS SOPs are for 1:1, 2:2, 3:4 and 4:3, I understand). Mission dependent.

its the Missile Sequence ID number
What is the function of this in RL (not implemented as u say) ?

Short answer, the aircraft radar system and Aim-120 missile use an interconnection datalink with 4 unique and separate transmit/receive frequencies (sub freq’s also apply), in order to distinguish missile guidance by its shooter, for a max of 4-ship flight members -shooters. Via this option the flight members can manually declare the channel freq’s that will use, in order not to jam each other shots (funny things will happen if 2 flight members have the same ID, be closer than 1nm, etc, huge area for future improvements here…) In rl, although not in all ops, it is better to use the far channels by a 2-ship attacking element, so something like this:
1 for lead
3 for wingman
2 for element lead
4 for elementwingmanFor now in bms this does nothing.

I dont think you can actually edit the subset in BMS. I think it just overwrites the ID instead.
So the ID Sequence number selects a predetermined sequence of ID numbers for missiles fired, in order. For instance, if you select ID sequence 1 and then fire three missiles, they will have missile IDs 6, 5 and 8, respectively. If you had selected 3 instead of 1, the missiles you fired would be IDs 2, 1 then 6, instead.
As the missile ID determines the set of frequencies (frequency hopping in use) for the missile guidance instructions, if you double up on missile IDs, you can get interference with one missile following instructions meant for another missile. As well, the ID determines the frequencies used by the missile radar in the terminal phase, so you can additionally get interference if launching against nearby targets, by getting reflected RF that was emitted by a different missile.
So ultimately the goal of separate IDs is to minimise mutual seeker interference for the missiles in flight, and to allow shot doctrine that supports more than one missile in flight per element at a time.

So, if i as a leader choose 3 and my wingman is on 3 . . . in that cenario if we are in a formation and shoot Aim-120 at the same time . . . this could be confusing for our radars to keep in touch with the missiles and evetually loose connection to the missiles ?
-
Missiles will act as jammers for each other
-
frequency hopping in use
There is no hoping in there, freq’s are unique and standard.

As I’ve said each main selectable channel number has 4 sub-channels beneath, these again in specific freq’s range but randomly selected by the radar and NOT by the pilot (he is not even aware of the actual used then), thus you have 25% change to ride the same freq emission with your wingman if you have the same channel number selected. What will happen is something like, the most “powerful” emission based and on geometry/distances could erroneous ride missiles.

Makes sense; it’s a bit like 2.4Ghz wireless channels. Best to to keep adjacent APs so many channels apart to minimise overlapping and collisions etc.

Ahhh, got it, thanks.

Interesting that the manual instructs how to select the subset then…
-
Ahhh… those manuals…

Granted, you would probably not be using the aircraft this one refers to I imagine.
EDIT: actually, you know what? Cant find the section I was thinking of. Perhaps I am just mistaken here.

Yup, by ID… so when you have two missiles with same ID…
