Mike LaConto, Avionics Manager at Stevens – Greenville, South Carolina said, “Archangel is the newest addition to our vendor roster.  We are particularly drawn to the performance and low cost of the Archangel catalog for Part 25 IFR aircraft. It’s a game changer.”

Deb Bailey

Deb Bailey has joined Archangel Systems as a critical player in its marketing efforts. She started at Archangel in February 2013 as a part-time technical writing intern while completing her Master of Technical and Professional Communication at Auburn University. Her main duties then were proposal reviews and editing project reports.

Since graduating in August 2016, Deb’s role has escalated considerably. Bill Dillard, Director of Sales and Marketing says, “While Deb’s official title is Technical Writer II, she’s wearing many hats for Archangel. She crafts our marketing collateral, performs pre-sales market analyses, manages our social media and web presence, and is a driving creative force on everything marketing. She’s made herself quite valuable to us and we are happy to have her on board.”

As an example of Deb’s character, she also has a new role in the community. She now volunteers at the Lee County Humane Society on weekends.

Troup Brazelton, Kitty Greene, Michael Greene

October marks Archangel’s 24th year in the aerospace and military marketplaces. The company, founded October 1, 1992 in Auburn, Alabama by G. Troup Brazelton and Michael E. Greene, began as a developer of large format touch-screen displays, engine data systems, AHRS and air data systems for civil aviation. The focus was on experimental class aircraft.

In 2001, Archangel made the strategic decision to concentrate on highly certified sensor systems. Archangel now designs, develops and manufactures sensor systems for use in both fixed-wing aircraft and rotorcraft as well as ground vehicles. Its catalog of products contains air data, attitude and heading reference systems (ADAHRS), attitude heading reference systems (AHRS), precision inclinometers, autopilot controllers and cabin altitude/hypoxia warning systems.

Dr. Michael Greene, CEO says, “At Archangel we are dedicated to thinking out of the box such as combining MEMS sensors and sophisticated algorithms to achieve very high-level performance while at the same time reducing cost and size. It is for these reasons that the USAF has chosen us to design and produce systems for the F15.”

Among Archangel’s customers are Bell Helicopter, Lockheed Martin, Boeing, the US Air Force, Elbit Systems, Airbus Military, DRS, Erickson Air Crane, the Australian Army, Universal Avionics, and Aerosonic. Archangel products are in use on virtually every continent in fixed-wing, helicopter, tilt-rotor, and supersonic aircraft.

Archangel Awarded TSO for AHR75 AHRS

Archangel announces that it has received FAA TSO C201 approval to manufacture its newest product, the AHR75 Attitude Heading Reference System. The AHR75 AHRS is designed as a cost-effective primary source of attitude and heading data for both OEM production and after-market upgrades.

For OEMS, the principle benefits are budgets and pedigree. Size, weight, power, and price budgets are among the lowest in the industry. However, DO178C software certification is Level A - the highest level possible reserved for mission critical functions. TSO basis is the new C201, a much more stringent requirement for AHRS performance, particularly in rotorcraft.

In upgrade programs, the AHR75 addresses reliability and compatibility concerns head-on.  Mean time between failure is greater than 12,000 hours even in rotorcraft environments. And, all data inputs and outputs are per the ARINC 429 standard for AHRS, ensuring the greatest possible compatibility with existing avionics.

The FAA and EASA agree that all TSOs granted after March 2, 2016 apply bilaterally, so the AHR75 is certified in European aircraft as well.

AHR75 orders are being taken now with initial deliveries in late April. More information about the AHR75 and its potential value to you can be found at or by contacting Bill Dillard at This email address is being protected from spambots. You need JavaScript enabled to view it..

In 2010, Erickson undertook a major avionics upgrade for their iconic S-64 Aircrane. Archangel Systems was selected to supply its AHR150A ADAHRS and a custom flight controller, the AFC001, for the legacy autopilot. That was our wedding day.

Our marriage is celebrating its 5th anniversary this year, and it has been a true marriage. Early on, Archangel and Erickson worked together to beat down technical issues related to the high vibration levels of the S-64. Those efforts made the installation, and the marriage, much stronger. Our trust level is at an all-time high.

Since 2010 Archangel has won several Erickson Gold Supplier awards, but we’re most proud of how our products are helping Erickson in a hostile firefighting environment. We know that our growth and success relies on strong and capable clients like Erickson, and vice versa. We also appreciate how their contributions have impacted the position we enjoy in the aviation community. Happy anniversary, dear.
