9.6.1 Relative
Relative altitude in hundreds of feet and vertical trend information are
given for each target aircraft.
Note
: Values greater than 9900 feet are
shown as ‘99’.
The ‘-02’ indicates the target is 200 feet below your
current aircraft altitude. The up arrow indicates the
target is climbing at a vertical rate of greater than
500 fpm.
The ‘+05’ indicates the target is 500 feet above your
current aircraft altitude. The down arrow indicates
the target is descending at a vertical rate greater
than 500 fpm.
9.6.2
Traffic Absolute Altitude
The traffic processor may have an option to change the display of
altitude from relative to absolute. This is called ‘Flight Level’ mode by
some manufacturers. When activated, the altitude shown for target
aircraft will temporarily be shown in hundreds of feet MSL when below
18,000 feet and as a flight level when above 18,000 feet. The altitude of
your aircraft will be shown on the ST3400H display.
9.6.3
Traffic Alert Priority
In the case of simultaneous GPWS/TAWS and TCAS alerts,
GPWS/TAWS alerts have a higher alerting priority.
