 Instruments - Angle Of Attack Indicators
 
RITE ANGLE BUDDY SYSTEM AOA
 


The RiteAngle™ Buddy also uses electronics not available during design of the initial RiteAngle™ systems. Although it is similar to the prior RiteAngle systems, for aircraft with no flaps, The RiteAngle Buddy operationally, is a totally new design using an enhanced display.

Note: The Buddy is for aircraft without flaps only.

The RiteAngle™ Buddy is a modern, up to date system that accurately determines your aircraft’s angle of attack. This series uses an improved easy-to-understand LED display. This instrument is designed to FAA standards.
Green indicates safe, amber indicates caution, and red indicates danger.

In addition to the color of the LED’s the “arrows” show which way to put the nose to prevent stalling the aircraft. The Diamond of Green LED’s indicate the “On Speed” AOA, 1.3 Vso regardless of bank angle density altitude or any of the other variables where the airspeed is inaccurate. We introduced the LED display in 1995 and it has been so successful that all of our competitors now have an LED display available.

Vane (Refer to Image):
Next time you are getting on an airliner, look in the general area below the Captains and First Officers windows, about in the middle of the fuselage, notice a vane?? I had a vane in my nearly 19 years flying for a major airline, and in business jets several years before that. If it was reliable enough for me when I was carrying over 150 passengers plus my crew it is reliable enough for our homebuilt aircraft. The same polymer vane is used with the RiteAngle™ Basic as is used on our custom designed systems which cost $3500. We have wing, fuselage and jury strut mounts. These mounts will satisfy all types of aircraft from the simple ultralight to Jets and have been in use for over 11 years.

Note: Small vane (compared to standard vane) is more streamlined and smaller as requested by owners of aircraft cruising over 200 kts, however it requires the ball bearing sensor due to the reduced airfoil area (except with the Elite System). See Accessories.

 
  • Easy to understand - Green Safe, Amber Caution, Red Danger
  • Manual dimming to fully “adjust for your individual preference”
  • Set-Up requires no maneuvers that you didn't practice before solo
  • Same vane sensor in use for over 12 years
  • DOES NOT "TAP" INTO PITOT OR STATIC LINES
  • Wax your aircraft without disabling your Angle of Attack by wax obstruction in a pressure port
  • This instrument is designed to show when, if flown with precision, the correct AOA and correspondingly the safe approach speed for the current conditions.
  • If the Green LED’s are illuminated you are at a safe AOA and will not stall.
  • Dimmer standard
  • Standard Bright LED’s
  • Smaller Enhanced display, easier to mount in panel
  • Wiring connection provided, however buzzer/led & cutout switch are not provided.
  • Piezo Buzzer or Large Red LED in Panel @ Stall Warning
  • Cutout switch for buzzer or warning LED
  • Overall dimensions, Three PCBs assembled into one unit including display.
  • Size 1.1” wide 2.25” tall X 2.7” deep. This depth does not include LED’s or plugs.
  • Suggest making rectangular hole, recessing display and covering opening with a very lightly tinted plastic cover.
  • Actual dimensions of “viewed” display .57 wide X 1.1” tall
  • Display Uses T-1 (3mm) LED’s
