[ANSWERED] Go Around N1 TGT

[dlrk]

What value should be set for go-around N1 TGT? It looks like the TO value isn't displayed in flight, and and the checklists indicate this must be manually set.

Different SOPs use different values. One operator uses a flat 90.2 in TGT and others select the TAKE OFF thrust limit for go around. Either method is appropriate.

To add a little bit of detail, the N1 TO value is not displayed above a certain altitude, I think 15000, but could be wrong. You can set TGT above that. As the APU can also not be started until below 15000ft, I tend to do the thrust setting within the "In Range Checklist", where the APU is started and N1 target set.

The TO value decreases during descent, should it be re-updated before landing? Also (I mentioned this in a different post), an APR value also shows up. Should that be used.

EDIT: Answer: No, APR is the Automatic Power Reserve N1, not the approach N1
