      Hello, All!

      I am trying to change sighting options. You are supposed to press OSB 10 in MFD GM FCR. SMS-Right does nothing either.

      My jet is in A-A mode. Switching to A-G mode just gets me to AGR.

      Can somebody enlighten me?

        What do you mean by sighting options? SMS right?

            ok lets try and get more information - do you want to display the TGP image in A/a and or A/g Mode? or are you trying to view through the MAV missile seeker head using WPN page ?

              I think he is talking about IP/PR OA1/OA2.

                Yes. I am trying to understand Page 27 of the Training Manual BMS1-F16CM_34-1-1

                  Have a look at BMS1F-F16CM-1 page70 1.3.16.1 DEST , 1.3.16.3 VIP
                  Page 72 1.3.16.9 VRP
                  You will need to do some ICP work to get VIP/VRP OA sightings .

                    I appreciate you taking time to address my confusion!

                      The different sighting options are a bit confusing because they come from different places within the system and most have to be specifically enabled to appear in the rotary list and the rotary list is only applicable to certain modes. Unless you’re purposefully enabling it you won’t have 2 or more sighting locations to rotate through.

                      You should only expect to deliver weapons against these points in CCRP or LADD. In other modes like CCIP, MAN, DTOS these points will not be targetable and in some cases not even displayed on the HUD. By your FCR being in AGR it tells me almost definitely you are in CCIP which isn’t associated with sighting rotary.

                      We’ll start with perhaps the most straightforward example of a location to which weapons and sensors can be pointed other than the waypoints, offset aimpoint(s) (OA1, OA2). Every waypoint is more than just a latitude, longitude, height and a time. There are also offset data for two points, OA1 and OA2. These can be seen and edited through the DEST DED page (LIST 1 then SEQ) as well as predefined by the DTC. Normally the values for the OAs are 0 range, 0 degrees, 0 height which turns them off (they’re only on if range or height is non-zero in value). Every single waypoint from 1 to 99 can have OA1, OA2, both, or neither enabled and they can all be different values. You’ll see them in NAV or in CCRP but they are hidden in AA or CCIP.

                      Provided you’ve entered some enabling values for OA1 and OA2 for steerpoint 5 and you approach CCRP toward steerpoint 5 you’ll have the following options in rotary: STP, OA1, OA2. The rotary can be cycled by pressing the OSB on the MFD bezel or TMS right. You’ll also see the OA triangles on the HUD.

                      –-

                      The above is worth trying out and experiencing alone before considering more factors. The next concept is mostly the same as before but with some slightly new concepts. What follows can be used with or without OAs as explained above to a mix-and-match preference.

                      Visual Initial Point (VIP) (LIST 3 on DED) mode is a toggle (0 M-SEL to select) option which renames the “STP” steerpoint location to the new label “IP” for target. It also adds a new point “TGT” which is an entered offset from the steerpoint. One major difference is that there is not a VIP offset point defined for every steerpoint but only one for the entire airplane. In the data for the VIP the pilot chooses to which steerpoint that data will currently apply. The rotary of sighting options will be: TGT, IP (really steerpoint with a change of name)***.

                      There is one other offset point possible with VIP and that is the pull-up point (PUP). It is only visual and cannot be used as a targeting location. As such it is not in the rotary selection of targeting locations.

                      Visual Reference Point (VRP) is almost exactly the same thing as VIP except that in VRP the steerpoint is not the target location. The point offset to the steerpoint is the target. The sighting will be: RP, TGT (really steerpoint with a change of name). The PUP is also available the same as in VIP.


                      Snowplow (SP) is drastically different than all of the above to the point where I would recommend to not consider SP to be the same topic as the other things. All of the above are somehow related as permanent steerpoints or their rigidly-defined offset locations. Snowplow enables the pilot to define a point in the world which has absolutely nothing to do with any of the permanent steerpoints or other data programmed into his jet. For example in CCRP with GM radar mode selected and the SP button having been pressed the system is waiting for the pilot to designate any point in the world as a temporary steerpoint. Once a location under the radar cursors is selected that becomes effectively the steerpoint around which the attack occurs. If the radar is slewed away from this designated location then those are true system deltas and the CZ command will return the cursors to that temporary point. None of the above points OA1, OA2, IP, RP are compatible at all with SP.

                      **Take note Leech’s warning about IP-TGT label swap for VIP.

                        Be aware that sighting rotary on the A-G FCR has the TGT and IP sightings mixed up. When TGT is selected it is labeled as “IP” and vice versa.
                        Also the PUP circle is drawn at the selected bearing and range from the TGT, it should be drawn at the selected range and bearing from the IP.

                        Just getting this out so you don’t get get confused when giving VIP a shot.

                        These are known bugs.

                          I see quite a few differences between expected and BMS behavior. It’s a little more complicated than just the labels being switched.

                          First OAPs should never be the bomb solution or navigation points. Unless their purpose has changed significantly they should be where the radar looks only. For example if STPT 3 is the target but is not radar significant you might make a OAP onto a hospital 1000’ to the west which is. The result is when OA1 is selected the radar is looking at the building but the navigation solution, bombing solution, TD box should still be on the desired target (steerpoint) while the FCR cursors are on the hospital.

                          In BMS if you pick OA1 in sighting rotary selection this becomes your target, navigation destination, TD box location… not good! Those poor orphans are going to get a MK84 for Christmas. OAP should never have a bomb impact on them. OAPs are a way to bomb forward while looking sideways.


                          For VIP and VRP method I only remember one is opposite to the other in construction. There is one type where steerpoint is target and the other type where steerpoint is not target, but I can never remember which is which! So I have to look it up in the book.

                          VIP - Steerpoint is IP, everything else is relative to it.
                          VRP - Steerpoint is target, everything else is relative to it.

                          I looks like TGT and IP points are mixed up like you say. Automation and INS updating is even more suspicious. I am designating with HUD SOI and suddenly my STPT is 400nm away. It should be possible to both overfly and remote INS update with TMS forward in VRP for example.

                          Possibly “STP” should never be shown in AG master mode even if VIP/VRP is not used, instead TGT should be shown. “STP” I think is for NAV master mode only.

                          In several cases in BMS when changing sighting option the diamond and TD box are moving around with the selection. I think this is incorrect possibly. Instead I believe it is likely that TD box always stays on target and diamond on VRP/IP regardless of target selection or FCR LOS. The bombing solution and TD box switch to IP or RP when they are selected seems in error.
