Visual-Initial-Point and System Point-of-Interest issue

[cpt.ocram]

Hey.
First, I’d like to congratulate you for the great job you’ve realized with BMS 4.33.
I’ve encountered some strange things with the VIP-TO-TGT behaviour. First of all, in VIP mode according to the chapter 1.2.6.3 of the “TO BMS1-F16CM-34-1-1” manual, the steer point is the VIP then we should define TGT and PUP positions from that VIP. I noticed the TGT position is defined from the VIP as expected but the PUP is defined from the TGT. We have a TGT-TO-PUP instead of VIP-TO-PUP. From my point of view I find it more logical in that way but my point of view doesn’t count, question is which one is wrong? The manual, the simulation or both.
Then I met another strange thing with the System Point-of-Interest, maybe linked to the previous one. I am in A-G mode with VIP selected and AG radar SOI in the MFD1. When I select TGT as SPI the radar cursor points on the steer point and when I select IP as SPI the radar cursor points on the TGT position that I’ve defined in the DED VIP-TO-TGT page. I think it should be the opposite; the steer point is the IP.
I checked with TGT-TO-VRP mode and there is no problem. It which works as planed.
I don’t remember I had those problems with 4.32. Is it a known issue or do I misunderstand something.

Oddly the manual says “Range and bearing from the IP or RP coordinates to the steerpoint are entered on the DED (or DTE).” That’s possibly sloppy wording, from-to instead of to-from.

It should be VIP-TO-PUP for VIP, TGT-TO-PUP for VRP. In IP sighting all points are defined as offsets from the steerpoint directly (TGT, PUP, OAPs). In RP sighting the same (IP, PUP, OAPs). It’s never chained 2 or more points relative to a steer. It’s probably just a copy-paste error talking about VRP or VIP mixed up.
