TM 1-1510-225-10 3D-22 The  types  of  areas  stored  in  the  database  and the   abbreviations   used   to   denote   these   areas   are detailed in Table 3D-4. Only  the  outer  lateral  boundaries  are  stored  for Class  B,  Class  C,  CTA,  and  TMA  airspace.    These special use airspace areas are stored as cylinders of airspace so all altitudes below the upper limit of these areas are considered to be in the area. Table 3D-4.  Special Use Airspace DISPLAY EXPLANATION ALRT Alert Area CAUT Caution Area CL B Class B CL C Class C CTA Control Area (outside the USA) DNGR Danger Area MOA Military Operations Area PROH Prohibited Area REST Restricted Area TMA Terminal Area (outside the USA) TRNG Training Area WARN Warning Area The  message  prompt  for  a  special  use  airspace alert   will   occur   when   the   aircraft   is   approximately 10 minutes from penetrating the outer boundary.  It will also    occur    if    the    aircraft    is    within    approximately 2 nautical   miles   of   one   of   these   areas   even   if   the aircraft  won’t  actually  penetrate  the  area.    The  pilot selects  the  amount  of  vertical  buffer.    If  one  of  the areas    is    penetrated,    another    message    will    state, INSIDE SPC USE AIRSPACE. 3D-12.  AIRPORT PAGES. There are eight airport pages for every airport in the published database. The  database  primary  area  contains  public  use and   military   airports   that   have   a   runway   at   least 1000 feet in length. a.   Airport 1 Page.  Refer to Figure 3D-19. NOTE The   APT   1   page   has   a   different   format when   it   is   displayed   as   one   of   the   nine nearest airports.  (1)   Airport identifier.  An arrow precedes the identifier if the airport is the active waypoint. (2)   Airport name. (3)   If the airport underlies the outer boundary of Class B or C airspace, CTA, or TMA, the letters CL B,  CL  C,  CTA,  or  TMA  will  display.    If  the  airport  is military, the letters MILTRY will display. (4)   The  latitude  and  longitude  of  the  airport reference point. KORL EXECUTIVE CL B N 28^o 32.71’ W 81^o 19.99’ APT 1 Figure 3D-19.  APT 1 Page b.  Airport  2 Page.  Refer to Figure 3D-20.
