What is the mode flow for Altitude “Track” mode in a 1124?

The course fine mode is ignored after the “caapture” high gain period, 6 seconds?

Then, the 590a-3K sets a clutch, and error out is fed to the FD computer, the “PitchSteer” through to the AP AMP(?).

 

Later WW S/N’s repeat the time constant over to the AP as well as the FD computer.

F900 Troubleshooting

How do I load the Perf Data Base in a NZ2000

Insert the USB key with the regular Nav Data Base.  The Aircraft Data Base files are on the same disk.
On the “DATA LOAD page, the 2R key should say ‘Aircraft DB”.  … If the stick has the DB on it, and it is plugged in to the data loader correctly.
Choose f900V2 or some such.
Page 6-172 of the pilots guide.
You must load both sides seperatly.

My performance values do not seem to be correct (ceiling altitude splits, cruise alt splits,
ETE’s, Fuel Estimates)
1. Verify that the proper Aircraft Database is in use. You can do this by looking on PERF INIT
page 1, under ACFT TYPE. This should correspond to your specific aircraft.
2. If the ACDB is incorrect (or to clear and reset ACDB performance to the default values) reload
the correct ACDB. The ACDB is available on either floppy disk 1 or 2 or the USB thumb drive
(as appropriate) of your monthly Navigation Database update.
Repeat all Data Load, Tail # and V-Speed Label steps on all CDUs.
3. Verify that SmartPerf Learning is turned
ON
on all FMSs until performance values are as desired.
At that point, turn
OFF
SmartPerf on all FMSs. Leaving SmartPerf
ON
for an extended period can

cause a divergence in the performance data saved in the individual FMSs, causing problems
