Hello, i have a question, in the hgs manual provided here : http://jlaroche.com/cqfa/280-BVN/Documents_BVN/B737_9701-1071%20Rev%20C.pdf it says, that to set the HGS in PRI mode one needs to set it on the

 

HGS control panel, or push the TO/GA button which will set it for you regardless of the mode displayed on the control panel, the thing is, i can't set it with the TO/GA button, i did some go-arounds in AIII mode, and

 

the pushed the TO/GA button, but it didn't change.

 

Is there something i need to do to obtain this behaviour ?

There is a selectable option in the FMC so that while on approach, the HUGS doesn't automatically switch to AIII mode.

Right, Klocek. FCOM 10.22.3 tells the same.

NO AIII indications after TO/GA push was a problem, because I have to set other HUD mode manually. I just didn't thought to look to manuals.

You can write a support ticket, so they will add it to SP2 (of course if Ryan or Paul haven't read this post yet).

I also can't seem to get the HGS test to work either.
