Preflight
Note: A TX FLT is indicated if the Strut switch is configured to be active
and the aircraft is on the ground.
Soft failures are those which can cause limited system operation, Radar
data will still be displayed but the flight crew should be aware that the
display does not necessarily represent the true weather. Soft failures
are typically configuration problem, stabilization problems, or some sim-
ilar problem.
Soft Failures:
Annunciation Cause
TX FLT alternating with ANT FLT Configuration module not
being read
STAB LMT Stab. Is exceeding ±30˚
STAB OFF Alert that the scan is not being
stabilized
PREFLIGHT
PREFLIGHT WARNINGS
Do not turn the radar on within 5 feet of containers of flammable or
explosive material. The radar should never be operated during fueling.
Do not attempt to operate the radar until you are completely familiar
with all safety information, including that on pages 58 through 61.
The system always transmits in the ON mode, unless the aircraft is on
the ground and the radar is interfaced to the strut switch. The radar
transmits in LOG mode if the radar is not interfaced to a Bendix/King
radar graphics unit. The system never transmits in the OFF, SBY or TST
modes.
Accomplish the following procedures completely and exactly.
1) Place the radar controls in the following positions:
• Function switch to TST
• Tilt to UP 7 (as shown on the indicator display, upper right corner).
The test pattern will appear. See that the test pattern conforms to the
illustration (The test pattern is sized to fit the 80 nm range and can be
scaled with the range buttons), and observe the “update” action as a
small ripple moves across the display along the outer edge.
