TM 1-1510-218-10 3B-41 NEXT PAGE ^– If   all   the   runway   thresholds and outer markers aren't contained  on  one  page,  this field    is    used    to    view    the remainder  that  are  contained on another page. (15)   Waypoint   Duplication   Page.      When   an identifier  is  entered  in  a  waypoint  identifier  field  and multiple definitions for this identifier exist in the system data    base,    the    waypoint    duplication    page    will    be displayed. SEL COUNTRY ^– The  number  associated  with: the   desired   country  may  be entered in this field. IDENTIFIER TOP ^– The  identifier  having  multiple definitions  stored  in  the  data base. A listing of the countries containing the same waypoint  identifier  will  display under   IDENTIFIER   TOP.      If an identifier for an intersection has been entered, a "T" or an "E" will be delayed next to the country  name  to  indicate  that the  intersection  is  terminal  or en route. (16)   NAV  Pages.    There  are  two  NAV  pages (NAV  1  and  NAV  2)  alternately  selected  by  pressing the NAV key. NAV 1 PAGE ^– The NAV 1 page format varies    somewhat    depending on    whether    the    method    of operation is OBS or AUTO/LEG. (a)   OBS Method of Operation Display. USE ^– The  number  displayed  is  the active waypoint number.   When     using     the     direct     to feature (DIR) is displayed. ID ^– The    identifier    code    of    the active waypoint. DIS ^– Distance to the active waypoint in nautical miles. ETE ^– Estimated time en route to the active  waypoint  in  hours  and minutes.    This  value  is  based on the present calculated groundspeed,   assuming   that the actual track is equal to the bearing to the waypoint. GS ^– Groundspeed in knots. TAS: ^– The colon (:), when displayed, indicates  this  is  an  enterable data  field,  only  when  there  is no true airspeed source available.        A    true    airspeed may  be  manually  entered  so that  the  system  can  make  a wind calculation. WIND ^– The computed wind using the TAS.      Displayed   in   degrees true  and  knots.    This  field  will display dashes if the computed wind is less than 10 knots. BRG ^– The bearing from the aircraft's present  position  to  the  active waypoint. HDG ^– The current aircraft heading. >POS RAD MKC DIS ^– The  aircraft's  present  position displayed in terms of a navaid,    and    the    radial    and distance    from    it.        Another navaid identifier may be manually inputted. The present position will be referenced  to  that  facility.    If the navaid is manually changed, the system will resume automatic navaid selection forth is field in approximately 1 minute. POS ^– The  aircraft's  present  position coordinates    in    latitude    and longitude.         The     pilot     may change   the   present   position back    and    forth    as    desired between the navaid identifier, radial,    and    distance    format and    the    latitude/    longitude format  by  placing  the  cursor over     the     >POS     field     and pressing the CLEAR key.   When    an    ILS    frequency    is active the POS block displays the    ILS    frequency    and    the radial    and    distance    display dashes. (b)   Auto/Leg Method of Operation Display. LEG ^– Active leg of flight plan.
