7.2.7 Product Identification
The Part Number Identification Label for each CWAP LRU is located on the rear panel and contains the
following information as shown in Figure 25.
7.2.8 Finish and Color
The paint color of the CWAP is medium texture black. The bottom surface of the mounting plate is unpainted
and contains a clear, RoHS compliant coating per MIL-DTL-5541, Type II, Class 3. The unpainted surface
is provided for bonding of the CWAP enclosure to the aircraft airframe.
7.2.9 Materials
All materials used in the construction of the CWAP are inherently non-nutrient to fungus and do not support
combustion. The materials are of the best commercial quality, and will not blister, corrode, crack, soften, or
show other immediate latten defects that affect the storage, operation, or environmental capabilities of the
unit after any or all of the test specified.
Materials used in the CWAP have been selected in accordance with the appropriate flammability
requirements of Code of Federal Regulations FAR-25.853a.
7.2.10 Weight
The CWAP weighs 3.66 lbs.
7.2.11 Cooling Characteristics
The CWAP is designed with passive cooling.
•
Operational Power Dissipation: 20.0 W Max
•
Operational Power Dissipation: 13.5 W Nominal
7.2.12 Installation limitations
The CWAP is intended to be installed in the crown of the cabin to provide adequate RF coverage of the
WiFi signal. An installation where there is a potential for falling water requires a drip shield. Installations
per ARINC 628 part 7 (Stand Alone) shall always have the minimum air gap spacing as follows:
•
Bottom (G1) = 0.00”
•
Left (G2) = 1.00”
•
Right (G3) = 1.00”
•
Top (G4) = 1.00”
•
Front (G5) = 3.00”
•
Rear (G6) = 1.00”
Installations violating the above air gap spacing must be approved by Telefonix PDT engineering.
There are no minimum installation distances between CWAPs. The maximum distance shall be determined
by aircraft type and configuration and content, e.g. throughput considerations.
Radiation Hazard: Maintain a safe distance when in operation. The device should be installed to provide a
minimum distance of 27cm to nearby persons while in operation. Remove power if working within these
distances.
