N1 Limit Page
This section describes the in–flight version of the N1 LIMIT page. See the FMC
Preflight section for a description of the preflight version of the N1 LIMIT page.
Normally, N1 limits are automatically specified. Pilot selection of other limits is
allowed.
Pilot selection of a reduced climb mode does not change the automatic selection
for other phases of flight.
Pilot selected mode is automatically replaced by AUTO selection when the
autopilot next changes vertical mode.
The active thrust limit is used by the autopilot and is displayed on the thrust mode
display.
An optional increase in available cruise thrust limits is available via a custom
Loadable Defaults Database (LDDB). The default cruise N1 thrust rating is CRZ
where cruise N1 limits are used as the default cruise thrust rating. The optional
setting is CLB where climb N1 limits are used as the default cruise thrust rating.
