TM 1-1510-218-10 3-79 for   navigation.      Insufficient   number   of   satellites   or inadequate satellite geometry to accurately determine the position within 3.8 nm. (43)   SET  FUEL  ON  BOARD  ON  OTH  5  IF NECESSARY    -    Appears    when    the    KLN    90B    is interfaced with a fuel flow computer that allows the fuel on board to be set. (44)   SYSTEM    TIME    UPDATED    TO    GPS TIME  -  Appears  when  the  KLN  90B  system  time  is automatically   updated   to   GPS   time   by   more   than 10 minutes.   (45)   USER  DATA  LOST  -  Appears  when  the unit    determines    that    the    internal    memory    backup battery  is  dead  or  that  some  other  internal  failure  has occurred which has caused all user entered data to be lost. (46)   VNV   ALERT   -   Appears   when   a   VNAV operation  has  been  programmed  on  the  NAV  4  page and the estimated time to start the climb or descent is approximately 90 seconds. (47)   WAYPOINT   ___    DELETED   -   Appears when  a  waypoint  used  in  a  flight  plan,  or  the  active waypoint, no longer exists as a result of updating the database.  The waypoint is deleted from flight plans in which it was used. (48)   WPT ANNUNCIATOR FAIL - This message  displays  when  there  is  a  failure  of  the  KLN 90B WPT  annunciator  drive  circuitry.   To  determine  if waypoint alerting is being given, check the display of the KLN 90B. bj.   Status   Line   Messages.       These   are   short, operational  messages  that  are  displayed  in  the  lower center segment of the screen. (1)   ACTIVE  WPT  -  Appears  if  an  attempt  is made to delete a waypoint on the OTH 3 page and the waypoint is the active waypoint. (2)   D  CRS  XXX°  -  Appears  when  the  KLN 90B  is  in  the  OBS  mode  and  is  interfaced  with  an external  indicator  which  the  KLN  90B  cannot  change the selected course  and  the  pilot  performs  a  direct  to operation.      Since   the   KLN   90B   cannot   change   the selected  course,  the  pilot  is  given  a  message  for  the OBS value to set the indicator to. (3)   DUP IDENT  - More than one waypoint of that type has the same identifier. (4)   ENT  LAT/LON  -  A  reminder  to  enter  the location of a user-defined waypoint. (5)   FPL  FULL  -  An  attempt  has  been  made to add a waypoint to a flight plan that already contains 30 waypoints. (6)   IN   ACT   LIST   -   Appears   when   a   user- defined  VOR  is  the  active  waypoint  and  attempt   is made to change the stored magnetic variation of this VOR.      The   magnetic   variation   cannot   be   changed while the VOR is the active waypoint. (7)   INVALID    ADD    -     Appears     when     an attempt is made to add a waypoint to an approach. (8)   INVALID DEL - Appears when an attempt is made to delete a waypoint from an approach. (9)   INVALID ENT - Appears when an attempt is made to enter invalid data, e.g., 30 FEB 96. (10)   INVALID  REF  - Appears with an attempt to create an invalid reference waypoint. (11)   INVALID VNV - Appears when a waypoint  identifier  has  been  entered  on  the  NAV  4 page if the waypoint is not valid for VNAV operation. (12)   NO    ACTV    WPT    -    Appears    with    an attempt to activate the OBS mode if there is no active waypoint. (13)   NO    APPROACH    -    Appears    with    an attempt to arm the GPS approach mode when there is no approach loaded into the active flight plan. (14)   NO APT WPTS - Appears when the APT type pages have been selected if the KLN 90B doesn't contain  a  database  cartridge  and  there  are  no  user- defined airport waypoints. (15)   NO  INT  WPTS  -  Appears  when  the  INT type pages have been selected if the KLN 90B doesn't contain  a  database  cartridge  and  there  are  no  user- defined intersection waypoints. (16)   NO    INTRCEPT    -    Appears    when    an attempt is made to recalculate the intercept point on a DME arc and the actual track doesn't intercept the arc. (17)   NO NDB WPTS - Appears when the NDB type pages have been selected if the KLN 90B doesn't contain  a  database  cartridge  and  there  are  no  user- defined NDB waypoints. (18)   NO SUCH WPT - Appears when there is no   waypoint   in   the   database   corresponding  to  the identifier entered on the reference waypoint page.
