TCAS I Theory of Operation and Symbology
•
The display may not be in the correct viewing mode to show the
intruder. The relative altitude modes for the display (KMD 550/850)
are:
- Normal mode: -2700 feet to +2700 feet
- Above mode : -2700 feet to +9000 feet
- Below mode: -9000 feet to +2700 feet
Other control head / display combinations may vary on the altitude
bands.
•
Some displays do not always allow the same range on the sides and
aft as out the front. The selected range denotes the range out the
front, and the sides and aft will be shown to a lesser range.
•
TCAS I does not display other aircraft deemed to be on the ground.
When own aircraft is below 1750 feet AGL, any aircraft within 400 feet
of the ground is considered to be on the ground, and therefore not dis-
played (TCAS I must be co
nnected to a radar altimeter for this feature).
