You can boresight Maverick without touching TGP.

I'm trying to follow along with Chuck's guide section 2.6.2, Missile Boresighting for the Maverick.

I was under the impression that the goal of BSGT was to align the TGP with the MAV WPN display so pilot was certain the missile was targeting the correct target/location.

However it appears to have no effect... I can move the TGP to one location, switch to MAV WPN and lock a target. Pressing BSGT appears to have no effect other than cause the MAV circle indicator on HUD to jump slightly. The TGP box indicator is still not aligned with the circle, nor is the TGP pointing at the same location or moved at all since I moved it.

I'm at a loss as to what the exact purpose of bore sighting is and the expected pilot work flow. Perhaps I'm mis reading the display and BSGT is some kind of check, eg. stays highlighted if HUD/TGP target matches MAV target? Or maybe the purpose is to apply the missile target, then switch stations so the goal is to pre-target multiple MAV stations for rapid launches?

After playing with bore sighting some more, it does not appear to move the TGP to point toward MAV WPN target, instead usually adjusts the MAV target indicator on HUD to match the TGP tracked location. So it appears to be a calibration type effect.  Once the pilot has manually located the same location on both TPG and MAV, and boresighted, moving the TGP points the MAV to the same location.  If I intentionally mis-align the two sensors and press BSGT, the MAV will not point to the same location as TGP when panning around.

That's exactly what boresighting is. You're trying to get two sensors, in different places on the jet, to point at the same thing.
