What is
the RiteAngle 2000?
According to the designer the system
" accurately
determines your aircraft’s angle of attack". It does this by
monitoring the relative air entering a wind vane mounted on your
ultralight. This then sends a message to a sensor that displays the
angle in a series of lights on "display."
The
" RiteAngle™
2000 LEDs
display the angle you select,
not the angle determined by the system manufacturer.
Each LED is independently set to the exact
angle you wish it to illuminate. This eliminates the need for excessive
LEDs. When correctly installed and calibrated, higher angle of attacks
are indicated with more illuminated LEDs than lower angle of attacks.
"
It
was interesting to watch as this was demonstrated using a "model
plane" mounted on a board, as the angle of attack increased the
lights on the monitor increased in number and brightness.
The
Rite Angle 2000, will also incorporate an audio warning, which can be
routed to a pilots helmet and intercom.
The
warranty on the Rite Angle 2000 is 1 year unlimited and 3 year
limited.
The
complete RiteAngle™
2000 system
consists of the following components:
·
Ultra-bright, full sunlight visible, wide angle LEDs auto dimming
to the brightness required from night to full direct sun.
·
Simple push button set-up
·
Calibration “keypad” which is unplugged and removed after
simple in flight calibration
·
Vane of preformed injection molded polymer
·
Voice audio stall warning
·
Display module
·
20 million rotation life sensor in use for over 3 years
·
Logic module mounted behind instrument panel, out of sight
·
Specialized wiring included (Aircraft wiring to vane and flaps
sensors not furnished)
LEDs
EM
aviation consultant Bill Lang of Interface
Displays, Inc. outlines the benefits of RiteAngle™
2000 LEDs below:
1.
“Solid state high reliability—average life is 100,000 hours
vs. 10,000 (10:1)
2.
Low power consumption
3.
Able to withstand shock & vibration much better than a
Tungsten Filament Lamp or Electro-Mechanical .
4.
Compact package size with variety of colors available
5.
Reduced weight
Interface
Displays, Inc
is changing most designs to LED illumination because of these mentioned
benefits. Currently,
it is being used on major airframes with new designs.”
Display
The
display is surface mounted to the instrument panel. The space required
is 1.0” wide and 2.4” high. The RiteAngle™
2000 system
supports two displays, if required for a tandem aircraft. Each display
independently dims as necessary.
Calibration
RiteAngle™
2000 employs
a simple-to-use color-coded “push button” calibration system with
Voice assistance. No
unusual in-flight maneuvers required.
Flaps
Flap
option is required for aircraft with flaps.
(See options link) For each of the flap positions simply repeat
the “flaps up” calibration of pilot-set LEDs.
Pitot/Static
System and the RiteAngle™ 2000
The
RiteAngle™
2000 is completely
separate from the pitot static system. If a break in the pitot or static
system line occurs, it will not affect the RiteAngle™,
nor will a failure in RiteAngle™
affect the pitot/static system as in other systems.
Back-up
System
For
a entirely separate back-up AOA system, add a small 12V Gel Cell battery
or (8 AA pen cells). RiteAngle™
2000
has an automatic switchover which switches to the back up battery in
case of aircraft electrical system failures.
