Part# 10-05682
MFR Model# CYA-100


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.

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!

Q: Does the Angle of Attack CYA 100 have an STC for a Piper Cherokee 180?

The CYA 100 is FAA approved under 14 CFR 21.8(d). No STC is required.

Q: Can the CYA-100 be self installed or does it require an avionics tech?

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.

Q: Does this Angle of Attach CYA-100 system require a flap position switch?

No, it does not.

Q: Can this CYA-100 AOA cockpit indicator be installed in the panel in the pilots view in the horizontal instead of vertically?

Per the installation manual there appears to be no restrictions on mounting the display horizontally.

Q: Can the vane probe for the CYA 100 be acquired heated for icing conditions?

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.
