5. For the majority of the en route portion of the flight, you select the
NAV 4 page’s moving map display. Pressing the right B
button, you select the 30 nautical mile range scale using the right
inner knob. Moving the cursor to Menu? And pressing
F
brings up the display menu on the screen. You then use the right
knobs to select APT:on and SUA:on so that nearby airports and
special use airspace (SUA) are shown on the moving map
display. While the menu is displayed, select the track up map
orientation (TK
З З ) as well, Pressing the B button again
removes the menu from the screen.
6. Since it is a good idea to not rely on just one navigation source,
you suggest we cross check the KLN 89(B) position against other
equipment in the aircraft. The NAV 2 page indicates we are
presently located on the Texarkana (TXK) VOR 68 degree radial
at a distance of 19 nautical miles. By tuning our NAV receiver
and DME to TXK, we are able to confirm that this is the correct
position.
3.18.3 TERMINAL AREA
1. About 50 nautical miles from Austin’s Mueller airport we start
preparing four our arrival. Viewing the APT 5 page for KAUS
you determine that the ATIS frequency is 119.20 MHz and tower
is 121.00 MHz.
2. A few minutes later, the message prompt begins flashing. When
you press
C
, the message page advises Airspace Alert -
Austin CL C - Below 4600 ft - See KAUS freq-Press CLR.
The Special Use Airspace Alert feature has determined that you
are within 10 minutes of penetrating the Austin Class C airspace.
When you press
E and view the APT 5 page for KAUS, you
see that the Class C airspace frequencies are sectorized. You
determine from the APT 5 page that the proper frequency to use
is 124.90 MHz since we are Northeast of Austin and 124.90 MHz
is the appropriate frequency to use from 3 degrees to 170
degrees. You turn to the NAV 4 page so that we can see the
outer boundary of the Austin Class C airspace relative to our
location and route.
3. After you call Austin approach control for clearance into the Class
C airspace, you view the rest of the APT pages for KAUS to
determine the field elevation and available runways.
4. After landing, the KLN 89(B) is turned off either by rotating the
KLN 89(B) power knob to OFF, or with the avionics master
switch if one is installed.
