2. Regulatory Compliance
The QP1xx series products have been qualified to RTCA Standard DO-160G for
temperature, altitude, voltage spikes, power input, and radio frequency emissions /
interference for cockpit devices. The installing agency shall determine the regulatory basis
against which to install this device.
Installations have been performed as a Minor Alteration with appropriate logbook entry in
accordance with guidance provided by the FAA.
3. Limitations
None
4. Installation Procedures
4.1 Planning
The USB connector protrudes from the face of the unit approximately 0.14”. A standard
installation utilizes an aluminum instrument panel thickness of 0.060” to 0.090”. Should the
installation call for placement in a panel thicker than 0.14” or if it is desired to install the
device in a recessed area, care should be taken to determine the space required about the
perimeter of the USB connectors. Consider the PED devices that will be charged and allow
adequate clearance between the Quiet Power unit and adjacent equipment.
The USB connector requires a square hole through the instrument panel and two mounting
screw holes. Refer to Section 7.3 Appendix C Mechanical Drawings for detailed panel
information. You may also install the device in a standard 2 ¼” or 3 ⅛” instrument panel
opening using either an optional Quiet Power panel or a fabricated panel.
You may choose to install the Quiet Power device using either #6-32 screws or #4-40
screws. The #6-32 screws are aligned along the device vertical centerline and the #4-40
screws are adjacent to the connector. It is not necessary to install the device with more than
2 screws (i.e. two #6-32 or two #4-40).
If you select #4-40 mounting screws, choose the engagement length such that it will not
penetrate deeper than 0.330” / 8.2mm into the body of the Quiet Power unit. Minimum
engagement is 0.260” from the face of the unit to the end of the screw. The following table is
presented for reference.
Panel Thickness
Screw Length
Penetration Depth
0.060 / 1.5mm
0.375 / 9.3mm
0.315 / 7.9mm
0.090 / 2.3mm
0.375 / 9.3mm
0.285 / 7mm
Electrical installation of the unit requires a dedicated protective device, either circuit breaker
or fuse. Refer to Appendix B for sizing and wiring information. Installation shall be performed
using acceptable methods, practices, and techniques as specified in FAA Advisory Circular
43.13-1B and 43.13-2B.
