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.
STANDBY AIRSPEED
INDICATOR
The standby airspeed indicator displays aircraft
airspeed (Figure 16-50). It measures the
ram and static air pressures directly from the
pilot-side pitot-static system, and presents the
airspeed on a single pointer indicator. The
pointer is referenced against a dial marking to

display the indicated airspeed. VMO is marked
with a red line at 250 KIAS.
To determine MMO limits, compare indicated
altitude to the placarded altitudes, and determine
the corresponding limiting calibrated
airspeed (KCAS) from the table.
When relying only on standby airspeed,
use caution to remain below
VMO and MMO.
Green and red LEDs on the upper left corner
of the bezel provide self-test indications during
power-up.
NOTE
When power is applied to the standby
airspeed indicator, the green and red
LEDs flash and the standby airspeed
indicator needle rotates clockwise to
the maximum limit, then counterclockwise
to the zero-park position.
After completion of the needle travel
test, the needle returns to the measured
pressure, and normal operation of the
instrument begins.
If the red LED illuminates or the green LED
is dark, the instrument is not operational and
maintenance is required.
The instrument pointer may be tested by pushing
the built-in test (BIT) switch on the lower
right bezel.
STANDBY ALTIMETER DISPLAY
The standby altimeter displays aircraft altitude
(Figure 16-51). The instrument measures the
static air pressure directly from the pilot-side
static system. It presents the baro-corrected altitude
on a digital readout at the top center of
the instrument dial, and a pointer displays the
precise altitude on the dial markings. A
barometric-setting knob is on the lower-left
corner of the altimeter. The setting appears in
a digital readout as hectoPascals (MB) on the
lower-left face and inches of mercury (INHG)
on the lower-right face of the instrument dial.
Green and red LEDs on the upper left corner
of the bezel provide self-test indications during
power-up.
