Handoff not working and avionic fault
-
Hello all,
I’ve tried using the hand-off function with AGM-65D and I’m having a hard time understanding what’s happening.
I have my missiles ready and uncaged, TGP in IR-point on a target. Then the message “hand-off in progress…” is displayed but, after that, my Master Caution switch on and I can read “Avionic fault TGP HAND” on the fault panel. Am I missing something or is this a bug ?It might be related so I’m writing it down here; I often have an “IFF fault” message while starting my plane, something I had never seen before.
Thank you in advance for your answers.

Hi,
Mavericks has a built-in boresight errors, so you need to first do the boresight procedure on every Mav stations before you can Handoff successfully. For more information please RTFM.

You really really need to read the AGM-65D/G MAVERICK MISSILE chapter of the -34 (TO-BMS1F-16CM-34-1-1.pdf in your \Falcon BMS 4.33\Docs\Falcon BMS Manuals folder), especially the Targeting Pod E-O Delivery (Handoff) section from p163 and the AGM-65D/G Missile Boresight Procedures from p165.
Once you understand the theory you can practise boresighting until you can do it in your sleep.
This is tricky at first so take it step by step.
Also consider reading the AGM-65 chapter of the new Training Manual. Red Dog takes you step by step through a whole TE there.

Nowhere in the manual does it say its mandatory to use this function. It says it must be done to improve precision and shorten the time to handoff.
“The AGM-65 mounting procedure induces an unknown amount of misalignment of the launcher. This misalignment must be removed to improve accuracy and shorten the time required to achieve a handoff.”
As I understood it if you don’t do the boresight procedure then it’s only longer to achieve the correlation.And it seems that the game does not do the procedure when you are taking a plane already started up.

Have some faults after starting plane and switching MCC/FCC on is normal and caused by transient currents during switching stuff on. It’s like in real jet, just hit CLR on TEST MFD page and continue your preflight.

The alignement must be done in-flight - it is hard to do it on the ground, you must have a high contrast object far away in order to avoid parallax errors.
If you dont do it, not only will the correlation be longer, but it has a much higher chance of failed handoff as well.

Also, you will need an active weapon to align, and MAV has a limited ON time… Yeah, RTFM guys…

Well… basically there is a chance that the Maverick Handoff will work even without boresight procedure, but it’s a pretty low chance.

That’s an interesting answer. Thank you. I am know wondering why the engineers decided to display an error message while indeed it’s not really an error but the result of a failed attempt. However this is another matter.

Well I’m not a RL F-16 engineer but from an engineer POV it’s simple, the system has no way to know if the failed Handoff is because of bad Boresighting or from a faulty Maverick, for example. So it registers a fault just so someone will check it later anyway.

If you check your test page after a HNDF FAIL PFL, you will see 2 MFLS
TGP HNDF FAIL 018 is a missile boresight correlation fail.
TGP HNDF FAIL 019 is missile boresight correlator out of toleranceIf the boresight is successful, you might get TGP HNDF FAIL 09 and TGP HNDF FAIL 10 in failed a attempt to handoff.

I haven’t gotten through so many manuals yet (400 pager per day is about my limit ^.^) but are all these MFL codes written down somewhere in the reading ahead?

PFL (Pilot Fault List) faults are listed in the -1 p179-181. These are what the pilot will see and should be interested in.
MFL (Maintenance Fault List) test numbers are not written up (we don’t have a Maintenance Manual), though we do have them for the TFR for example in the -34 on p85 as the pilot may well be interested when he’s going to be strapping into his jet and cruising just above the ground at night at 400 knots or more.
Because I know you love this kind of stuff the complete list of TGP faults (you’ll need to check the TEST page for these if you get a HADF FAIL) is:
PFL MESSAGE TEST NO. EFFECT OF FAULT ON SYSTEM TGP BUS FAIL 3 Total loss of TGP function TGP HADF FAIL 9 No AGM-65 hand-off or slaving TGP HADF FAIL 10 No AGM-65 hand-off or slaving TGP HADF FAIL 18 No AGM-65 hand-off TGP HADF FAIL 19 No AGM-65 hand-off
As you don’t have to fix your own jet in BMS or in real-life though most of them are not really that useful for all but the most passionate aficionados.
We’ll see about future editions though…

True enough.
@Leech Thanks for this complement of information.
