TM  1-1520-240-10 3-3-26            NOTE To access P, depress the LTR LEFT key fol- lowed by the 6 key. Another way to access P is to display waypoint 99 then depress the INC key or display waypoint 00 then depress the DEC key. Waypoints  cannot  be  recalled  by  location name/ICAO identifier. h.  Procedures  for  Entering  Variation  and  Landing Mode Data. (1) Set MODE switch to MGRS position-altitude entered/displayed  in  meters  (LAT/LONG  may  also  be used-altitude entered/displayed in feet). (2) Set DISPLAY switch to WP/TGT position. (3) Select the waypoint desired by directly en- tering the two digit target number or depressing the INC/ DEC keys. Observe the waypoint number entered and position data. (4) Depress the ENT key and observe the way- point number, variation and/or landing data if entered. (5) To enter a magnetic variation and/or landing mode data depress the KYBD key to select the field for entry and enter the desired data as shown in steps 6 through 10 below. To end the entry operation depress the ENT key. (6) Entry of variation: as an example, consider entry of a variation of E001.2. Depress keys E, 0, 0, 1, and 2. The decimal point is inserted automatically. If no landing mode data is to be enter depress ENT to com- plete the operation. Display indicates: E001.2_. NOTE An asterisk appearing in the variation fielded indicates the variation is not entered. Varia- tions may not be entered for waypoints con- taining target motion. (7) The bottom two lines indicate the MSL alti- tude, desired glideslope, and the desired inbound ap- proach course (IAC) to the indicated destination. As an example, consider entry of a glideslope of 8_ an IAC of 270_ and an altitude of +230 meters, for destination num- ber 25. (8) Depress the KYBD key to blink altitude field. Depress the INC/+ key to enter a positive altitude, de- press keys 2, 3, 0 (the leading zeros may be omitted) for the altitude of 230 meters in the example. (9) Depress  the  KYBD  key  to  blink  the  glide slope  field.  Enter  glideslope.  The  maximum  allowable glideslope is 9 degrees. In the example enter 8 for an eight degree glideslope. (10)   Depress the KYBD key to blink the inbound approach course field. Enter a three digit inbound ap- proach course angle. In the example enter 2, 7, 0 to enter a  270  degree  inbound  approach  course.  Depress  the ENT key to complete the operation. i.  Procedures for Entering Target Motion and Direc- tion In MGRS mode, target speed is entered in km/h; in LAT/ LONG mode, target speed is entered in knots. (1) Set the MODE switch to LAT/LONG (MGRS may be used). (2) Set the DISPLAY switch to WP/TGT and se- lect the target number desired (00-69 or 90-99) by direct- ly entering the two digit target number or INC/DEC keys. Observe  the  waypoint  number  entered  and  position data. (3) Depress the ENT key and observe the way- point number, variation and/or landing data if entered. (4) Depress the ENT key and observe the target speed and direction page. (5) To select target speed depress the KYBD key  twice  and  enter  the  target  speed.  The  maximum target speed that may be entered is 50 knots. Fill leading zeros before entering. (6) To  select  the  target  direction  depress  the KYBD key and enter the target direction. (7) To end the entry operation depress the ENT key. At the time ENT key is depressed and released, the target position will begin to be updated as a function of time based on the speed and direction entered. NOTE To abort/cancel an entry of target motion, en- ter  a  target  speed  of  000  using  the  above procedure. j.  Procedure    for    Entering/Displaying    Datum    or Cleaning All Waypoints. (1) Set  the  MODE  switch  to  MGRS  position (LAT/LONG may also be used). (2) Set    the    DISPLAY    switch    to    DATUM/ ROUTE. (3) To select the datum field depress the KYBD KEY. (4) Entry  of  datum:  as  an  example  consider entry of 25. Depress keys LTR 2, 5. Depress the ENT key. The display shall show DATUM:25. (5) To  clear  all  waypoints,  variations,  landing data and target motions, enter RDW for the spheroid. k.  Procedure  for  Entering  Sea  Current  Speed  and Direction for Water Motion Correction.
