ABX Air Announces New UPRT Simulator Capability

Wilmington, OH – October 18, 2017

ABX Air, Inc. announced today its plans to update and certify its B767-200 Full Flight Simulator to provide Upset Prevention and Recovery Training (UPRT). This advanced training capability, enabled through the use of the StallBox® solution developed by Bihrle Applied Research Inc., allows pilots to more accurately train to recognize and recover from a full aerodynamic stall. This training capability was previously unavailable in the simulated environment due in part to the lack of full stall models and appropriate instructor training aids, which StallBox® provides.


The ABX Air B767-200 simulator will have the ability to conduct UPRT in accordance with U.S Code of Federal Regulations (CFR) Title 14 Part 60 Directive 2 by December 2017, well ahead of the FAA’s 2019 deadline for incorporating such training into all Full Flight Simulators used for commercial pilot training.


StallBox® is the first FAA-qualified solution on the market to meet the FAA's newly enhanced requirements for stall modeling and instructor displays (CFR 14 Part 60 Directive 2). Currently in use by both commercial and military customers, StallBox® provides airlines and training centers with a robust solution that leverages 40+ years of expertise in aerodynamics data collection and software modeling of complex flight regimes.

Alaska Airlines Leads the Industry in Safety with First FAA-Approved Flight Simulator Featuring a Full-Stall Model

Cutting edge innovation provides advanced, more realistic training for pilots

SEATTLE, May 5, 2016 /PRNewswire/

Last week, Alaska Airlines became the first commercial airline in the world to receive FAA certification of an enhanced full-stall model in a flight simulator, which helps pilots train to recognize and recover from a full aerodynamic stall. While this type of mid-air stall is extremely rare, simulator training helps pilots prepare for worst-case scenarios.


In advance of the 2019 deadline set by the FAA, Alaska Airline's simulator engineering group completed the upgrade

and certification process for one of its 737-800 simulators with a StallBox. The StallBox together with a set of instructor led

tools allows the simulator to more closely mimic the actual aircraft in a similar situation, making sure pilots are well equipped

if they ever encounter a full stall in real life. The Birhle Applied Research product meets the FAA's newly enhanced requirements for "upset prevention and recovery training."


"Safety remains our top priority and ensuring we have cutting edge training for our pilots helps us to maintain our

industry-leading position," said Tom Kemp, Alaska Airlines' vice president of flight operations. "This project has been in

the works for two years and is an example of how we continually strive to be ahead of the curve and go beyond the

industry requirements to deliver excellence and ensure a safe operation."


Before this new model, training for full stalls has been primarily academic. The simulator could do the "approach to

stall," but wouldn't show accurate behavioral cues once in the "stall." The National Transportation Safety Board (NTSB)

looked at a number of stalls that took place during commercial operations, and determined that often times the pilots

were unable to recognize the stall and that there was a need for more hands-on training for pilots. The key learnings

from these incidents helped to refine this training and will not only help pilots recognize and recover from a stall, but

more importantly, prevent them from occurring in the first place.


"The Air Line Pilots Association, working with Alaska, supports this valuable and ahead-of-schedule improvement to the

first of Alaska's simulators," said Doug Branch, chairman of the Human Factors and Training Committee for the Alaska

Master Executive Council of the Air Line Pilots Association. "This investment illustrates the value Alaska puts on providing

industry-leading training, which leads to enhanced safety for our passengers and crews. We look forward to the benefits

this enhanced training tool will provide, and applaud Alaska for moving so quickly to implement it."


Alaska Airlines, a subsidiary of Alaska Air Group (NYSE: ALK), together with its partner regional airlines, serves more than

100 cities through an expansive network in the United States, Canada, Costa Rica and Mexico. For reservations, visit For more news and information, visit Alaska Airlines' newsroom at
