Altitude Buffer
The ‘ALT BUF’ field, located directly below the Other
SUA alarm settings, is an altitude buffer that allows you
to set a specific altitude range for triggering SUA alerts.
This helps add an extra margin of safety to your estimat­
ed altitude error to ensure you receive SUA messages in
time to avoid unwanted SUA intrusions. The default
altitude buffer is 200 feet.
The value of the altitude buffer is added to an esti­
mated altitude error calculated by the GPSCOM 190.
This value is then added or subtracted from your present
GPS altitude. If the final adjusted altitude falls within an
SUA, you’ll receive a message. If the adjusted altitude
does not place you in an SUA, you won’t receive the
message.
To enter an altitude buffer;
1. Highlight the 'ALT BLIP field. Enter a buffer value and
press
Arrival Alarms
The next function available from the alarms/CDl page
is the waypoint arrival alarm, which will activate an alarm
message once you’ve come within a set distance of a des­
tination waypoint. Three options are available:
Off' No arrival alarm will sound.
Auto- An arrival alarm wall sound one minute before
the destination, based upon your current speed and
course.
On- An arrival alarm will sound at the alarm distance
specified in the distance field for the destination way-
point.
(The ‘On’ setting will only provide an arrival alarm
for the final destination waypoint of the active route).
To set the arrival alarm:
1. Highlight the arrival distance field and press
2. Enter a distance (up to 99.9 nm).
3. Press to select the arrival field.
4. Use the arrow keys to select 'ON', 'Off, or 'Auto' and
press
