Vertical Power, developer of innovative solid-state switching
systems for experimental aircraft covered by ANN
last Summer, has launched their VP-100.
The VP-100 uses microprocessors and solid-state switches to
provide advanced electrical system features, circuit protection,
simplified aircraft wiring, and the ability to eliminate dozens of
modules, breakers and switches typically found in today’s
aircraft. The VP-100 is the newest addition to Vertical
Power’s family of solid-state switching systems for
experimental and light sport aircraft.
“In the last five years or so there has been a very
significant shift in general aviation aircraft from mechanical
systems to all-electronic systems. Trim, flaps, EFIS, ignitions,
and engine monitoring functions have all gone electronic, yet the
electrical system in your aircraft is the same as it was 50 years
ago,” said Marc Ausman, President of Vertical Power and an
“The VP-100 is designed to bring solid-state switching to
a broad range of experimental aircraft. If you’re building an
all-electric aircraft then the VP-100 is a great way to simplify
the electrical wiring.”
Aircraft wiring is simplified using the VP-100. The builder
simply runs wires from the VP-100 to each electrical device such as
a radio, transponder, landing light, flap motor, or battery
contactor. Switches, circuit breakers, diodes, mechanical relays,
complex bus architectures, and various modules are mostly
eliminated. The VP-100 is designed to be very fault tolerant and
allows the builder to incorporate numerous backups if desired to
eliminate any single-point failures.
“I recently retrofitted my wife’s RV-4 with the
VP-100 and an EFIS and graphical engine monitor. I replaced the
vacuum system with a backup alternator and installed electric trim.
The VP-100 made re-wiring the aircraft much simpler than the
original wiring,” said Tom Velvick, RV builder and pilot.
“The VP-100 fit right into the limited panel space in the
Each of the eight switches on the VP-100 can be configured using
the setup menus to turn on or off any of the electrical devices on
the aircraft, and multiple devices can be grouped on a single
switch. This allows the system to be configured for the wide range
of designs found among experimental aircraft and allows future
changes to be made very easily.
In addition to full electrical device control, a few of the
