Ownship Symbol
The ownship symbol is a white triangle when the display orientation is
direction-up (true heading or true track-up are valid) and is centered
horizontally, but moved down to the lower one third of the screen. An
ownship velocity vector line uses ownship track and ground speed to
indicate 30 seconds of ownship travel.
The ownship symbol is a black/white circle when the display orientation
is north-up and is located in the center on the screen.
Obstacle Symbols
Obstacles are depicted as triangular shape objects that can be either
small or tall; colored as either cyan, yellow, or red; and shown as a
single object or as a group. Obstacles are shown when the display
range is 2, 6, and 12 nmi.
A small obstacle is shown for obstacles that are 200ft to <1,000ft tall.
Tall obstacles are shown for obstacles that are > 1,000ft. Obstacles
that are < 200ft are not shown on the TAWS screen.
Obstacle color is based on obstacle elevation (MSL altitude at the
top of the obstacle) compared to the aircraft altitude. Cyan colored
obstacles are > 1,000ft below the aircraft. Amber colored obstacles are
between 1ft and 1,000ft below the aircraft, and red colored obstacles
are equal to or above the aircraft altitude.
NOTE
While obstacles are enabled, TAWS is capable of
generating alerts on all obstacles included in the database.
However, due to incomplete obstacle data and display de-
cluttering techniques such as altitude ltering and obstacle
coalescing, every obstacle may not be depicted on the
Terrain Display.
