Lancair IV-PT
Marshall Michaelian's Lancair IV-PT is equipped with a complete
TSLM system as well as the FSM (Fuel Supply Monitor) system from VR Avionics
which monitors the aircraft's fuel transfer from the three main tanks to the header tank and engine in detail.

Marshall's panel
Maurits helped design the final layout of this panel, fabricated the fibreglass panel frame and designed / fabricated
the centre console with integrated cuircuit breaker panel.
The complete electrical harness design and fabrication of the panel and airframe was done by Maurits.
Marshall's FSM display can be seen just above the centre concole, while the TSLM display is on the panel.
This Chelton system has a certified AIU.

Lancair IV-PT
Jeff Tino is the owner of this turbine Lancair which is equipped with a FSM system to monitor the fuel situation
of the four fuel tanks onboard, as well as TSLM and EIU systems.
This aircraft was originally owned by Luisa Romero.

Jeff's panel
Maurits did the panel design with Luisa Romero and Ian Burnham made the plugs and molds for the panel and centre console.
Maurits did all electrical design and build of panel/airframe harnesses.
This aircraft has both FSM and TSLM displays, which can be seen on the left side of the panel.

Garmin Epic LT
VR Avionics supplies the propeller de-ice controller (PDC) for the Epic turboprops. It directly controls and monitors the current to the boots.

Garmin Epic panel
This panel was designed by Maurits and Rick Schrameck for Mark Dessy and it flew late April 2007.
It was the first Garmin 900X to go operational in the world!
All the electrical harnessing for the Garmin Epic integration was done by Maurits.

Chelton Epic LT
VR Avionics supplies a propeller de-ice controller (PDC) for the Epic turboprops.
It alerts the pilot should the current to the boots fall out of range.

|
Chelton Epic panel
This is an Epic designed panel that Maurits built and had a hand in designing some upgrades to accomodate a new MRU and prop de-ice in the wiring harness.

Lancair IV-P
John Cook's Lancair IV turbine (shown here with Tubine Legend)
has flown many hours with our TSLM, EIU and TSLM-PD set of instruments.

Introduction of TSLM display gauge and EIU system
The EIU feeds the OP Integrated EFIS with all engine information. The TSLM-PD
displays the engine information read by the TSLM and thus provides redundancy.
As a small way of showing our gratitude to John for all the help over the years, VR Avionics equipment for this aircraft were
provided free-of-charge.

Cessna 421 with Walter engines
Hendrik Venter of South Africa is in the process of re-engining a Cessna 421 Golden Eagle
with Walter M601D's - replacing piston with gas-turbine power.
Hendrik makes his plane available for ground engine testing to VR Avioncs.

In-flight Testing
About a dozen test-flights were performed on this turbine powered Malibu in Deland. VR Avionics sponsored the TSLM
and installation to gain valuable data. For example, we did a deliberate in-flight restart of the engine at 10,000 feet - no problem.

Still operational on their engine test stand, the TSLM provides detailed graphs for more
accurate engine adjustments.

Testing at Diemech Turbines
Two TSLM units (one as backup) were made available by VR Avionics for Diemech's engine test stand.
This provided us with a lot of useful data and Diemech with new tools for testing.
|
|
|
First Installation
The very first TSLM engine starts were done in Modesto, CA (Oct 03) and in Petaluma, CA (Feb 04). It worked first time up.
