Elements Of SA

Table 1 distinguishes between geographical SA, SA of aircraft position and movement, aircraft system SA, environmental SA and, more for military aircraft, tactical SA.

Geographical SA	own aircraft other aircraft terrain features airports cities waypoints navigation fixes position relative to designated features path to desired location runway and taxiway assignments path to desired location climb/descent points
Spatial/Temporal SA	attitude altitude heading velocity vertical velocity flight path actual values relative to assigned projected flight path projected landing time
System SA	system status functioning and settings radio altimeter transponders flight modes and automation deviations from correct settings ATC communications present fuel impact of degrades and settings on performance time and distance available on fuel
Environmental SA	weather formations and movement temperature icing ceilings fog turbulence, winds sun visibility IFR/VFR conditions areas to avoid flight safety projected weather conditions
