8.10 SUA ALARMS (ALARMS)
From the SUA Alarms Page you may
define which types of special-use /
controlled airspaces you wish to be
alerted of. Selections are provided for
Class B / CTA, Class C / TMA,
Restricted, MOA and Other airspaces.
“Other” airspaces include Alert,
Caution, Danger, Training and Warning
areas.
NOTE: The GPS 95 always provides alerts for Prohibited areas. No
selection is provided for this feature.
To turn an SUA alarm on or off...
· Using the arrow keys, highlight the on/off cyclic field beside the desired
airspace type.
· Press CLR to turn the airspace alarm on or off.
· To return to the Main Menu, press PWR/STAT.
SUA altitude limits are stored in the GPS 95's database as altitude above
mean sea level (MSL) if the actual limits are charted in the same manner. The
SUA Alarms Page provides an altitude buffer which is used to define at what
vertical distance from an SUA the messages (alerts) will be displayed. For
example, if you enter 500 feet and are flying above Class B airspace, the GPS
95 will provide SUA messages when you are less than 500 feet vertically
(plus the current position error) from the Class B ceiling.
CAUTION: If you fly above or below an SUA, then enter the SUA, the “Inside
SUA” message may be the only message provided! The “SUA Ahead”
and/or “SUA Near” messages will not occur if you are outside the vertical
limits defined by the airspace floor/ceiling plus the altitude buffer setting.
Some SUA altitude limits may be charted in terms of altitude above ground
level (AGL). If the actual lower limit of an SUA is charted in terms of AGL,
then the GPS 95 will alert you at any altitude below the upper limit. However,
if the actual upper limit is also charted as an AGL altitude, the GPS 95 will
provide the alert at all altitudes.
