NARCO AVIONICS AR850
1-6 7/03
Temperature Variation - Category B
Low Operation (-20
°
C) to Temperature may vary between
High Operation (+55
°
C). high and low limits at a
rate of 5 degrees C minimum
per minute.
Humidity - Category A
These limits have been tested under the Standard Humidity
Environment of: +50
°
C (+122
°
F) at 95% relative humidity, reduced to
+38
°
C (+100
°
F) with a relative humidity maintained in excess of
85%.
This cycle was repeated twice for a total of 48 hours of exposure.
Within 15 minutes after exposure, the units were operated and met
all specifications.
[TSO requires that all specifications be met within 4 hours after
exposure.]
Vibration - Category NMO
Maximum vibration limits are:
0.100" double amplitude from 5 Hz. to 17 Hz.
1.5 G constant acceleration from 17 Hz. to 500 Hz.
0.5 G constant acceleration from 500 Hz. to 2000 Hz.
Not Applicable - Category X

in Civil Aircraft, when recognized installation practices are
adhered to and are, therefore, not tested.
Explosion - Category X
Waterproofness - Category X
Hydraulic Fluid - Category X
Sand and dust - Category X
Fungus Resistance - Category X
Salt Spray - Category X
Magnetic Effect - Category Z
With this equipment operating, it may be placed at a distance less
