5. Verify that SHDG is not boxed. If it is, press the
SHDG pushbutton to unbox SHDG.
Note
Unboxing of SHDG must be performed
within 17 seconds of selecting GND ALIGN
on the NAV MODE switch or the boxed
SHDG will be selected and unboxed by the
system and deselection will not be available.
Verify latitude and longitude and enter correct values
if necessaryI.f new entries arer equired at this
time, the alignment time may be extended, depending
on the differences between the newly entered
values and those displayed when alignment
was initiated.
Alignment progressc an be monitoredb y observing
the QUAL and TIME acronyms and the alignment
scale on the MFD OWN A/C format. The indicator
on the alignmentp rogresss calec hangesR ooma “V”
to a diamond symbol at the fmt tic mark. This representsa
n 8 nm per hour estimatedn avigationq uality.
The secondt ic mark representsa n estimated2
nm per hour quality and the third an estimated 0.8
nm perh our quality.A t this point a dot appearsin the
diamond. An INS ALIGN COMPLETE message
normally appearsa t the top of the MFD display in 4
minutes. At this time the QUAL acronym is near or
slightly below 1 nm per hour and the pointer on the
align scale should be near the last tic mark.
During concurrent alignment, it is advisable to
monitor the SAHRS alignment progress by pressing
the SAHR pushbutton on the MFD. The OWN
A/C MFD format will show SAHR boxed; and the
QUAL and TIME acronyms and the align scale
now refer to the SAHR. A SAHRS ALIGN COMPLETE
message normally appears in approximately
2.5 to 3 minutes from the time when the
parking brake was set. The QUAL will be approximately
10 (nm per hour) at this time.
9. Alignment may bec ontinueda ftert he appearancoef
the INS ALIGN COMPLETE messageif time permits.
This will provide only slight improvement in
alignment quality but will provide some gyro biasing
and eliminate unnecessaryd rift in the INS mode, If
