Maverick training mission boresight question
-
From the manual:
pick it up visually on the TGP. Go NARO field of view to zoom in and obtain point track with TMS up.
The WPN page then shows HANDOFF IN PROGRESS STATION xI’m pretty sure I’m following the procedure detailed, I get a point track on the ship, but I don’t see that WPN page message.
Power on, 12 miles from steerpoint 4.
What am I missing?
-
Have to be in EO-PRE mode. Have to have the WPN format and TGP format both visible at the moment TGP point track is initiated. TGP point track has to be successful. Maverick has to not be tracking already.
-
Also, even after I have a completed handoff the fault list includes two items:
TGP 018
TGP 019If I clear them they both re-appear on the test page, and the master caution light illuminates.
All works correctly afterwards, and the handoff fault clears on the fault list panel, but there is still a fault listed.

Have your MFDs set up prior to running the mission. On the left MFD have FCR and WPN at least for the 2 out of the 3 modes (Left MFD OSD 12, 13, 14) and on the right MFD have at least TGP. Once you find ship using FCR, use DMS to switch left MFD to WPN page. If you have already warmed up the Mavs and hit uncaged for the first 1, you will see the ship on TGP on the Right MFD and also on the MAV view on WPN page of the Right MFD. Keep trying. Boresighting Mavs to TGP took me quite a few tries to be just OK at doing! You might also watch some great youtube videos on how to actually do it to help you (Krause has done quite a few good ones on various things).
-
The problem is, even after successfully boresighting I still have those errors, and can’t clear them. All works fine and I can take out the Zsu’s, but I’d like to clear the fault if possible.
-
I believe that after you boresight, you then clear all slews (simply start MRM mastermode and then immediately Cancel), then you perform a handoff again to each necessary station, once that is done, the errors should clear.
-
After boresighting try locking up the target again……if you boresighted properly (make sure you are in Alt hold ) you should get an attempt to lock message again and it will succeed and you will see a little C on the display. You should be able to clear after that IIRC.
-
If the only problem is the persistent MFL entry, it’s probably not going to be able to clear and stay cleared until the handoff situation is no longer being used. If you went back to NAV mode it should deselect the Mavericks and allow clearing the fault.
-
The odd thing is I get the “C” for completed handoff after I test it after boresighting. But the avionic, AV, fault is still listed as are the TGP errors on the test page.
I’ll have to have another look at it and make sure I’m getting the sequence exactly right.

Have you pressed the the CLR button in the test MFD page

Don’t forget the Search box in the top right corner. I typed in TGP 018 and this is what was found:

Yes. The list just re-populates and the master caution illuminates again.
I must have something out of sequence, or something, but I would have thought when you have a completed handoff the fault would clear.
-
Don’t forget the Search box in the top right corner. I typed in TGP 018 and this is what was found:
TGP HNDF FAIL 018 is a missile boresight correlation fail.
TGP HNDF FAIL 019 is missile boresight correlator out of toleranceI expect to get those errors with a handoff failure, but the point is I still get them after a confirmed handoff.
But again, I need to go back over it and see if something is out of sequence.
-
The fault isn’t dependent on succeeding on a second attempt. It’s probably something like you had a failure on a “handoff session” and it persists until the end of the session. Oddly I followed (probably) the training document’s procedure exactly and didn’t find the fault to be so persistent as described here. I’m curious about exact reproducing instructions.

As an aside, when doing the boresight calibration operationally you never incur a fault. By switching SOI to WPN after the handoff is initiated but before it fails, it is interrupted and no fault occurs while performing the BSGT. The instructions with the training mission are to demonstrate the fault only. I know this is separate from the behavior we’re talking about.
I try a reduced form of your procedure and get not the same issue.
1. Attempt handoff with un-boresighted missile, wait for fault generation.
2. SOI WPN, slew to track and BSGT missile.
3. Cycle in-out DGFT.
4. Attempt handoff again with boresighted missile, wait for completion.
5. CLR on TEST page, fault does not return.I then attempted the full procedure and could not get the issue.
I assume you’re generating the initial fault on step #3 in your post. We can ignore the F-ACK press because it does nothing. However when the PFL message (this includes the minimized “AV” in the corner) disappears is also exactly the same time when the MFL (TEST page) can be cleared without coming back. The PFL entry should clear exactly when the next attempted handoff completes (any missile). So the new hunt is to find a situation where you get a successful handoff but the PFL entry remains.

Thanks, Frederf.
I have no idea what’s going on with it. The one thing I have noticed is that when I enter the test page the “C” disappears over station 3.

Please post a video

I’m going to put up a temporary video as soon as I can render it. I did notice on a boresighting video that AV is still illuminated on the PFLD after boresighting. I’m guessing if he were to try to clear the fault list the whole thing would light up again. I have to assume AV is meant to clear.

(video removed as it has served its purpose and the boresighting process is incomplete)
