A fully assembled airframe wiring harness is supplied which provides

all the electrical interfacing required to operate the system.

All hardware and circuit breaker included, no assembly required at all…. just install!

Fully Approved Installation

Weight: 7.0 oz

The 320 and 640 maintain situational awareness in difficult environments

and make Controlled Flight into Terrain a virtual impossibility.

An outstanding installation where reliability and performance are priorities

INSTALLATION environments

Is engineered to be easy, and can be accomplished within one working day.

1- Involves initial fitting of the camera assembly to the hull

2- Installation of the airframe wiring harness

3- Final installation of the camera assembly

4- Installation of the LCD monitor and pedestal support

and with no airframe modification at all!

Step 1 involves initial fitting of the camera assembly to the hull location illustrated below.

After shimming with the supplied shim stack to correct typical airframe discrepancies,

the camera is then set aside for installation of the airframe wiring harness.

Step 2 involves installation of the fully prefabricated wiring harness

The illustration below details the wiring harness in red and is a typical install.

The following pages clarify the installation.

The illustration below shows the routing of the power supply leads.

The shielded positive input lead is routed along the main canopy conduit,

and the camera ground is connected to the airframe ground as shown below.

As the power supply lead is routed into the overhead console, any available location

is suitable to mount the toggle switch type circuit breaker, which is included in the kit.

Wiring Harness Step 2

System ON/OFF Switch

The power supply lead is connected to the circuit breaker through a short bus jumper.

With the overhead console reassembled, the wiring harness installation is complete.

The camera assembly is then connected to the wiring harness, and attached to the hull

in place if the inspection panel. All fasteners are supplied.

Only the LCD monitor and monitor support remain to be installed.

The monitor attaches to the adapter bracket. The glare shield attaches to the monitor

with thumb screws for easy removal. Finally, the video and power leads are attached.

Provision is made for adjusting the monitor left/right

and up/down to suit the eye position of the pilot.

THE IMAGE installation




The 320 on final approach allows you to see terrain, obstacles, and other aircraft in total darkness, and enhances the pilot’s vision throughsmoke, smog, dust and haze. It not only provides video imagery of the entire runway environment, but exposes details such as people, animals and vehicles on active runways and taxiways as well.



640 Approach installation

The 640 imager displays the

highest resolution available

In thermal imaging technology

Unlike other systems, that provide an image of “something that looks like an airport”, the TrueView EVS detail lets you distinguish taxiways from runways, and read runway markings, including the actual runway number. The competition cannot provide the image quality of the TrueView 640, even at twice the price!
