ATS Fail and N1 TGT

[4A4847]

During the "In-Range" checklist, I get an ATS Fail alert during the "APU / PACKS TRANSITION" line of the checklist (I'm using the automatic copilot to help with some of the checklist).

I'm not sure what I'm doing wrong, or what I need to do differently in order to prevent an ATS failure from occurring. I've seen a N1 TGT in the Thrust Limit menu, but that doesn't seem to work (unless maybe I'm setting an invalid target).

Any input would be appreciated!

What are you setting? And are you activating/selecting it afterwards?

I haven’t flown in a few days, but last I recall, I set the value in the N1 TGT field of the FMC to a value less than all values shown on the left side (maybe around 90.0). I had the 10th stage bleed selected also. Maybe I’m not activating it correctly/at all… 

What should I be doing?

Punching in 90-91% is fine. The “trick” is you have to then press the same line select key to activate it (goes magenta). Try it out next time.

If you’re descending for landing why not select TO thrust per the checklist?

Also acceptable. There are different real world SOPs. The hints will be updated to reflect that in the next update.
