Kohlman Systems Research
(KSR) provides complete flight test, instrumentation,
data analysis and reporting capability to gain RVSM airworthiness
approval.
Flight Test Support, Data Processing, Analysis and Reporting
KSR provides flight test support, including developing the flight test
plan (FTP),
coordinating the FTP approval with the FAA ACO, providing a flight test
engineer
to operate the flight test instrumentation and monitor the flight test.
After the
flight test is complete KSR provides the data processing, analysis and
reports required
to gain FAA RVSM approval.
RVSM Test Module
The KSR RVSM Test Module includes five pressure transducers and
displays. It accepts aircraft
115 VAC power and provides an RS232 output for computer data recording
for subsequent data
analysis. The five transducers interface with the KSR trailing static
cone (described below) and
the aircraft pitot and static pressure sources. The RVSM Test Module
has been designed for
easy installation and operation. A laptop computer is installed for
interface with the RS232
bus for data collection and data storage.
Trailing Static Cone
The KSR static cone system provides a convenient means of calibrating
the static source error
of the pitot-static system by providing an accurate measurement of the
ambient atmospheric pressure.
The system consists of a cone that is trailed at least one fuselage
length behind the aircraft.
Static pressure is measured well forward of the cone by flush static
ports on the line.
The cone stabilizes and aligns the ports relative to the free stream
flow.
 The cone is connected to the aircraft by a
steel cable inside the pneumatic pressure line.
This simple design eliminates the cost and complexity of retraction
mechanisms and can be used
on a variety of aircraft that cannot accommodate other, more complex
systems.
