The CYA-100 Angle of Attack system is the only affordable FAA APPROVED TRUE Angle of Attack system on the market today! Extremely light, and extremely small, the CYA-100 is easy to install, with no extra computer boxes or hoses. The vane driven sensor is magnetically coupled. There are no small pressure ports to plug and no ball bearings to seize. The microprocessor controlled display uses ten auto-dimming, hyper-bright, color coded LEDís so that itís easily viewable in direct sunlight, and wonít distract during night flight. The unique flush mounted and tinted display is so small it can be placed almost anywhere in, or on, the panel or glareshield. A unique warning tone at stall is easily interfaced to the pilotís headset or the aircraft audio panel. Plus, the unit is incredibly easy to program with just the push of a button.
CYA-100 Angle of Attack System, is an approved aircraft part labeled 14 CFR 21.8(d), per FAA Memorandum Policy Number AIR100-14-110-PM01.
Easy to install. Suitable as additional information for the pilot. Very good costomer service from manufacturer.
Love the simplicity of the install, calibration and the accuracy of the direct vane read. Price is right too!
It is great to see someone get back to the basics when it comes to AOA. The vane type device has been proven for many years on countless airliners and military aircraft. This unit is well designed and manufactured to the highest standards. In addition, installation and calibration are a breeze. It is a welcome addition to my Bonanza.
I purchased a CYA 100 for my Husky A1-B when they first came out, as did several other Husky owners at the time. Easy installation and set up - settings remain accurate over time. Nice to know exactly what the stall margin is when youre loaded with camping gear, down low next to the canyon wall in a steep river canyon landing over the trees into a short strip in the Idaho back country. It nice at other times too!
Nifty unit. I installed on my Seneca just aft of the nose. EXCELLENT customer service from manufacturer and simple to install.
The unit is easy to install and works well, but differs from the photos shown here in that it only lights up 1 led at a time. This makes it very hard to interpret when using peripheral vision when one is in a critical phase of flight, like approach to land. Its very hard to know which of the four Amber LEDs are lit, for instance, and therefore hard to use compared to systems that use a particular shape of led to indicate best approach angle or which light up a number of LEDs like from the bottom up so you can actually tell what AOA youre at.
Nearly useless. Doesnt light up multiple leds at once, so you might see orange in your peripheral vision, but that a long doesnt tell you much. The lights are not bright enough to notice them in bright conditions anyway. The audio feature isnt very helpful either because it only has 1 tone that comes on at stall. If this unit had 2 or 3 different types of tones, it would be MUCH more useful. This would allow you to come in slowly, and know how far from stall you are, while never having to look inside at the instrument. Would be helpful for coming in on the slow edge of the envelope, while dodging obstacles outside while landing on a short spot. I do a ton of off-airport, and you are busy looking for rocks and other obstacles outside, you dont want to stop and look inside to check airspeed or AoA. But this unit doesnt help in this situation. The reality is, once you get some hours in your plane, your rear tells you what you need to know, so these are not necessary. But if you are going to build one - it should be bright enough, and have enough audible functionality to actually give you some information without requiring you to take your eyes from outside the aircraft. And it gets worse from there... after about 3-4 months, it quit working. Started blinking, and acted like it required to be re-calibrated, but would not calibrate properly. Thankfully I ran the audio function through a switch so I could shut that off as it just started blinking red as if I was in a stall and the audio warning wouldnt quit. Ripped this piece of crap off and threw it away. Waste of over $600.
The CYA 100 is FAA approved under 14 CFR 21.8(d). No STC is required.
This depends on the aircraft it is being installed in. The CYA-100 is not designed for user install into a certified aircraft, however an experimental aircraft owner can do it. We recommend an A&P or avionics shop to install this system when going into a certified aircraft.
No, it does not.
Per the installation manual there appears to be no restrictions on mounting the display horizontally.
No, the vane probe cannot be used in icing conditions. The system is calibrated for an aircraft without ice, so any icing conditions vary the airflow so that the indicator cannot accurately indicate your AOA. If you encounter icing conditions, it is recommended to follow the POH.
