2.3 INSTALLATION PROCEDURES
1. The installer must consider the following prior to installation. Specific procedures for installation of
the Lynx NGT-9000, Detachable Configuration Module, Mounting Rack or tray, and Directional
Antenna (for TAS or TCAS option) are detailed in their respective paragraphs below.
• The installer must obtain installation approval (i.e. Supplemental Type Certification).
• Follow the acceptable avionics installation practices in FAA Advisory Circulars AC 43.13-1B
and AC 43.13-2B or later revision of these documents.
• It is the responsibility of the equipment installer to determine that the required aircraft viewing
envelope for the panel mount NGT-9000 is within the specified display viewing envelope(s).
Refer to paragraph 2.3.1.
• Bonding impedance between aircraft ground and the unit chassis must be less than 2.5
milliohms.
• It is recommended that the aircraft battery be disconnected before performing installation
procedure.
• Installers are responsible for obtaining installation hardware (i.e. screws, supporting plates, etc.)
beyond those parts that come with the installation kits.
• All antenna cables should be clearly marked to prevent inadvertent installation into the wrong
connector position.
• Tighten all screws to snug (i.e. only such torque that can be applied by hand) unless specific
torque instructions are given.
• After installation, refer to the Installation Checkout section for calibration, power-up and
ground testing procedures.
• When installing a remote mount NGT-9000R a CP-2500 Control Panel (or compatible control
panel) is required. Refer to the CP-2500 Installation Manual (0040-17251-01) for installation
procedures (or third party publication for other compatible control panels).
2. Electrical equipment chassis, shield/ground terminations, antennas, supporting brackets, and racks
must be electrically bonded to the aircraft's main structure (metallic aircraft) or instrument panel
(composite aircraft). Compliance of the electrical bonding should be verified by inspection using a
calibrated milliohm meter. An equivalent OEM procedure may also be substituted.
• The electrical bond should achieve direct current (DC) resistance less than or equal to 2.5
milliohms to structure local to where the equipment is mounted for metallic aircraft or tube and
fabric aircraft.
• The electrical bond should achieve direct current (DC) resistance less than or equal to 5.0
milliohms to the instrument panel for composite aircraft.
The antenna ground plane must be electrically bonded to the antenna baseplate. Do not remove paint
on outer skin of aircraft under the footprint of the antenna baseplate unless necessary to meet
bonding requirements. Refer to antenna manufacturer's installation instructions.
2.3.1 Panel Mount Location
1. The unit is mounted in the instrument panel where the touch screen display can be used to view
aircraft flight information and provide operational control.
• When installing with the TAWS Option, mounting this in the pilots primary field of view allows
the on-screen indications to meet the TAWS visual alerting requirements. Otherwise,
accommodations should be made to install the TAWS Caution and Warning lamps in the
primary field of vision.
2. The unit should be accessible for inspection, maintenance, or removal, and free from instrument
panel structural flexure and excessive vibration or heat.
3. The wiring and antenna cables should not run adjacent to heaters, engine exhaust, or heat sources.
