TM 1-1510-225-10 3A-104 NOTE An  offset  waypoint  (#OFF*)  can  be  input with  a  radial  based  on  the  LAST  TK  value and distance calculated from the LAST GS value   as   well   as   the   time   elapsed   from power  off,  provided  significant  changes  to aircraft    track    or    groundspeed    have    not been made.  If the aircraft has turned or if the  speed  has  changed,  the  pilot  should estimate   the   track   and   distance   traveled since loss of power. 9.   Offset waypoint identifier – Insert. 10.   ENTER key – Press. 11.   Recorded  or  estimated  radial  – Insert LAST TK value or averaged value. 12.   Recorded  or  estimated  radial  – Insert LAST TK value or averaged value. 13.   Distance  –  Insert  calculated  distance in    nautical    miles    and    tenths    of    a nautical mile. 14.   ENTER key – Press. 15.   Waypoint    coordinates     –    Verify    for reasonability. 16.   ENTER key – Press. 17.   DIF  - Check. a.     If update is desired:  ENTER key - Press. b.     If   update   is   not   desired:      NAV, PLAN, FPL, TUNE,  VNAV, HDG, or   D    key  – Press to cancel the HOLD. y.   Creating/Changing Pilot Entered (Personalized) Waypoints.   A personalized waypoint may   be   created   by   entering   a   non-ICAO  waypoint identifier and inserting the desired position coordinates on the Waypoint page. The  CDU  has  nonvolatile  storage  for  up  to  999 waypoints that are retained in memory only if entered on a stored flight plan.  The ICAO identifiers stored in the     database     cannot     be     used     for     personalized waypoints. Select  the  desired  flight  plan  and  position  the cursor over the desired field.  If necessary, refer to the procedure for creating a flight plan or modifying a flight plan. (1)   Creating     Pilot     Entered     (Personalized) Waypoints. 1.   Personalized identifier – Insert. 2.   ENTER key – Press. 3.   Latitude   –   Insert   (N   or   S   first,   then degrees,   minutes,   and   tenths   of   a minute). 4.   ENTER key – Press. 5.   Longitude  –  Insert  (E  or  W  first,  then degrees,   minutes,   and   tenths   of   a minute). 6.   ENTER key – Press. (2)   Changing    Pilot    Entered    (Personalized) Waypoints. 1.   Personalized identifier – Insert. 2.   ENTER  key   –  Press.    Pilot  Entered WPT page will appear. 3.   Line select key – Press to position the cursor over POS field. 4.   ENTER key – Press. 5.   Latitude   –   Insert   (N   or   S   first,   then degrees,   minutes,   and   tenths   of   a minute). 6.   ENTER key – Press. 7.   Longitude  –  Insert  (E  or  W  first, then degrees,   minutes,   and   tenths   of   a minute). 8.   ENTER key – Press. NOTE If  an  offset  waypoint  from  a  pilot  entered waypoint is programmed, the RAD and DIS can     be     changed,     but     the     coordinates cannot be manually inserted. (3)   Creating    An    Offset    Waypoint.        This procedure enables the system to create a waypoint at a  given  radial  and  distance  from  a  known  point.    The known   point   (parent   waypoint)   may   be   any   stored personalized or database waypoint.
