ATI ESD has modified many different types of aircraft for many different missions. Those aircraft include the
S-61, S-76, S-92, King Air (BE200 and BE350), C-208 Caravan, Dash 8 and the CN235.
NVIS Lighting, cockpit and/or exterior, has been a focus, although electrical modifications have been involved
The airworthiness certification aspect has been central to all programs. Whether obtaining a complete FAA
NVIS operational STC or developing an STC support package for government airworthiness approval, ATI
ESD expertise and experience can be relied on.
ATI ESD cannot provide the details on many of the programs it supports. However, the following may give a
flavor of those missions:
C-130 NVIS Kit
In 2008, ATI ESD was asked by C-130 aircrew members to design and build them an NVIS primary flight
instrument filter kit.
The aircrews needed filters that they could place over their primary flight instruments that would work with
goggles and allow them to fly night NVG missions. They had some cockpit NVIS lighting already, but it was
marginal. They wanted filters that they could leave in place over the instruments all the time so that they did
not have to take them on and off. That meant they needed daylight readability over what were already dimly
lit instruments. It was a real challenge. They also wanted a “non mod” kit that did not have to go through all
the full Air Force aircraft modification approval wickets. And, they needed it NOW. – They were deploying to
This was a challenge for ATI ESD. ESD prided themselves in being an “OEM level” aircraft modification
company. Now, they were being asked to build a filter kit that would use Velcro to hold it in place. They would
also need to use the NVIS lighting standard called compatible, “subjectively works OK”, rather than the
standard of compliant to MIL S 3009. However, the warfighters needed it. So, they did it.
It worked. The resultant kit was given rave reviews by the aircrews that flew it in combat.
However, the Air Force system was nervous about having such a Velcro on, compatible kit. It was not until
ESD conducted a darkened hangar visual acuity MIL STD 3009 evaluation with Air Force observers watching
that the kit was officially found to work, not degrade the goggles and to be, in fact, “acceptable”.
This kit is flying combat missions today and units are still buying them.
