Data  entered  on  any  of  the  trip  planning  pages have no effect on the navigation data provided on any navigation or flight plan page. NOTE The    trip    planning    pages    rely    on    pilot- entered inputs for true airspeed, groundspeed,  and  fuel  flow.    These  pages do  not  utilize  inputs  from  the  fuel  flow  or air data sensors, if installed. Areas of special use airspace are displayed on  the  trip  planning  pages  without  regard to altitude. (1)   The     Trip     Planning     0     Page.          The anticipated  true  airspeed  and  winds  aloft  are  entered on the TRI 0 page so this information may be us ed on the other trip planning pages.  Refer to Figure 3-89.
