CHAPTER 10
SUA FEATURES EXPLAINED!
By now, the operation of the GPS 95's SUA features should seem easy:
· Messages are provided to alert you of nearby special-use and controlled
airspaces.
· The SUA Page provides additional information about each of the
airspaces.
· The Map Display graphically depicts the boundaries of these areas.
In this section we will examine the operation of the SUA features in more
detail by using actual examples. Beginning with a very basic example, we'll
look at progressively more complex scenarios to further your understanding
of these features. Remember, if you're in doubt about any SUA message,
crosscheck that information using the SUA Page and the Map Display (and
appropriate navigation charts!).
10.1 FLYING TOWARD AND ENTERING AN SUA
This first example is provided to review the function of the various SUA
messages. Referring to the figure on the following page, assume you are
heading due west toward Shirley 1 MOA. Shirley 1 extends from 10,000 feet
MSL to FL180 and you are currently at 10,500 feet. As you approach the
MOA at Location #1, a message appears, “SUA Ahead < 10 min”. This
means you are within ten minutes, based on your current ground speed and
track (projected course), of reaching the MOA's boundary. The SUA Page
indicates the estimated time en route before entering the MOA.
At Location #2 the message, “SUA Near & Ahead”, is provided, indicating you
are within two nautical miles of the MOA boundary and the MOA lies ahead
based on your current ground track. Again, the SUA Page indicates the
estimated time before entering Shirley 1.
Finally, at Location #3 you are alerted with the message “Inside SUA”. This
message confirms that you are now inside the boundaries of Shirley 1 MOA.
The SUA Page also indicates you are inside Shirley 1.
