SYSTEM ALERT
MESSAGE
DESCRIPTION
ACTION
IRS1 ENTER PPOS
IRS2 ENTER PPOS
IRS3 ENTER PPOS
IRS requests position initialization.
Message enabled for LTN-92 and
ADIRS interfaces.
Perform IRS initialization on POS INIT page.
Enter position on POS INIT page.
IRS1 ON SEC. POWER
IRS2 ON SEC. POWER
IRS3 ON SEC. POWER
IRS is on secondary power for more
than 10 seconds.
Advice maintenance.
LOW BATTERY POWER
The power level of the internal battery is
low. Manually-entered data may be lost
if there is a primary power interruption
during flight.
After any power interruption, monitor system
performance and re-enter data as required.
Advise maintenance.
MANUAL WPT
SEQUENCE
Sequencing to the next waypoint needs
to be manually initiated by the pilot.
This message is displayed in
conjunction with the NEXT LEG prompt
with legs requiring a manual termination.
This message also appears when the
FMS is flying an altitude-terminated leg
and a baro-corrected altitude is not
available.
Press NEXT LEG prompt (LSK 6R) when
required on the PROGRESS 1/4 or LEG 1/X
pages.
MLS CONTROL LOST
MLS radio failure
or
FMS cannot tune the MLS radio
(requested tuning does not match
feedback for 10 seconds).
Advise maintenance
NO APPR INTEGRITY
The predicted or actual GPS integrity
does not meet the requirements for
approach.
Activate the missed approach or use alternate
means of navigation (if available) to perform the
approach.
NO CRUISE – VNAV
LOST
The FMS cannot generate a climb
profile.
NOTE: The FMS invalidates VNAV
Performance function (no vertical
profile, no fuel and crossing altitudes
predictions).
Review the CRZ ALT data entry and enter a
lower cruise altitude or modify the lateral flight
plan to increase the distance between the
departure and destination airports. Otherwise,
do not use the FMS for VNAV guidance since
this is not possible without a valid vertical
profile.
NO NAV DATABASE
No navigation database has been
loaded.
Advise maintenance to reload navigation
database.
NO STEP CLB NEAR
T/D
After computing the vertical flight plan
profile and the location of a waypoint
with an altitude constraint above the
waypoint’s crossing altitude falls within
50 nm of the T/D.
Remove the altitude constraint on the waypoint
within 50 nm of the T/D.
NO STEP DES NEAR
T/D
After computing the vertical flight plan
profile and the location of a waypoint
with an altitude constraint below the
waypoint’s crossing altitude falls within
50 nm of the T/D.
Remove the altitude constraint on the waypoint
within 50 nm of the T/D.
NOT ON INTERCEPT
TRK
Current aircraft track does not intercept
desired course to fix.
This alert message appears after
executing a Direct-To with Intercept-
Course, or when flying a Course-to-
Intercept leg of a NavDataBase
procedure (SID/STAR).
Fly the aircraft to an appropriate intercept
course. Re-engage LNAV to capture new active
leg.
