Multiple XM Weather information products
can be displayed simultaneously on some
pages. Note that some XM Weather information
products cannot display with certain other
XM Weather products. Likewise, some XM
Weather products cannot display with certain
information from other sources. The NEXRAD
legend is shown in Figure 16-48.
MAP–XM WEATHER DATA LINK
Page
In the MAP page group, the WEATHER DATA
LINK page provides the maximum number of
views of XM Weather information products.
The range/pan joystick provides an interface
with many of the weather products.
When the map pointer is pointing to, or in,
a specific feature on the map, the center box
of the map pointer information bar gives information
on that feature. When pointing to
a specific symbol representing a weather
hazard, information is given about that hazard.
When the hazard is an area, and the map
pointer is on the boundary, or inside the
boundary of the area, information about the
hazard appears in the center box. When the
map pointer is in a place where multiple hazards
exist, only one is identified in the center
box; SIGMETs have priority.
For boundaries of hazard areas, refer to the
Garmin manuals.
On the main softkey menu, the MORE WX
softkey leads to more weather products.
Selecting some of these features may require
a more detailed softkey selection, such as specific
altitudes for winds aloft depiction, or
forecast periods (current, 12-hour, 24-hour,
etc.) for surface weather depictions.

Viewing METARs and TAFs
METARS and TAFs are available in text format
through XM Weather.
METARs and TAFs can be viewed by selecting
the WPT–AIRPORT INFORMATION page
and pressing the WX softkey. This changes the
page to the WPT–WEATHER INFORMATION
page (for the selected airport). On the
right side of the page are windows for METAR
reports and TAF forecasts.
STANDBY FLIGHT
INSTRUMENTS
The Mustang has four standby flight instruments
that can function independent of the electrical
system or any other system, including the
avionics. These instruments are the:
• Standby attitude indicator
• Standby airspeed indicator
• Standby altimeter
• Standby magnetic compass
Each 2-inch indicator is a self-contained unit.
Electrical power for these units comes through
the STBY INST switch from the right avionics
electrical bus. The bus connects to normal
DC power, and also has a dedicated 1.2 ampere-
hour standby battery. The standby battery
is in the nose and connects to the main electrical
bus for charging power (refer to Chapter
2—“Electrical System”). Circuit breakers for
the standby battery charging circuit, and each
of the standby instruments (except the compass),
are in the AVIONICS section of the
right CB panel.
The pneumatic instruments (airspeed and altitude)
bypass both ADCs and are directly
connected (pneumatically) to the pilot-side
pitot-static system. The magnetic compass
operates without external power. However, an
internal light in the compass receives DC
power from the same source as the other
standby instruments
STANDBY ATTITUDE
INDICATOR
The standby attitude indicator is a self-contained
unit that provides visual pitch and roll
aircraft attitude information (Figure 16-49).
The indicator contains an electrically powered
gyroscope, which maintains vertical orientation.
The instrument is internally lighted.
A PULL TO CAGE knob allows the gyro to be
aligned prior to flight.
The attitude indicator may be damaged
if the PULL TO CAGE knob is
released with a “snap.” To release,
pull to cage knob slowly in order to
avoid a “snap” release.
