“…The design was intended to be a 15.8% scaled model of a generic short to medium range twin-jet transport with aft mounted engines and a T-tail. The remotely piloted vehicle was built by Area-I 7 and delivered to NASA for use in loss-of-control-prevention research 8 being conducted under the NASA Aviation Safety Program. Due to NASA programmatic re-planning, that vehicle was not flown.…”

Tests of a generic T-tail transport airplane, in flaps-up configuration, were conducted using two wind tunnels, a water tunnel, and computational fluid dynamics. Static force and moment testing, forced oscillation testing and dye flow visualization test techniques were used. The purpose of the testing was to obtain stability and control characteristics for development of a research flight simulator aerodynamic database. The purpose of that database was for assessment of aerodynamic model fidelity requirements to train airline pilots to recognize and recover from full stall conditions. Preliminary results, at initial stall conditions, include: an unstable stall pitch break, and near-neutral roll damping. Preliminary results, at deep stall conditions, include: a potential static longitudinal trim condition at approximately 35 degrees angle of attack, large aerodynamic asymmetries, and localized unstable dynamic stability.

“…It occurs most often in poor visibility conditions, when reading the instruments correctly is most crucial. Spatial disorientation continues to be a serious safety risk, as it was estimated to have contributed to 12 % of loss of control accidents in transport and commuter aircraft, and 24 % of fatalities between 1996 and 2010 (Belcastro et al, 2017). The most prevalent form of spatial disorientation in aviation is the 'leans' illusion (Holmes et al, 2003;Navanthe & Singh, 1994).…”

In-flight spatial disorientation induces roll reversal errors when using the attitude indicator

We hypothesized that an incorrect expectation due to spatial disorientation may induce roll reversal errors. To test this, an in-flight experiment was performed in which forty non-pilots rolled wings level after receiving motion cues. A No-leans condition (subthreshold motion to a bank angle) was included, as well as a Leansopposite condition (leans cues, opposite to the bank angle) and a Leans-level condition (leans cues, but level flight). The presence of leans cues led to an increase of the roll reversal error (RRE) rate by a factor of 2.6. There was no significant difference between the Leans-opposite and Leans-level condition. This suggests that the expectation strongly affects the occurrence of an RRE, and that people tend to base their responses on motion cues instead of on information on the AI. We conclude that expectation and spatial disorientation have a large effect on piloting errors and may cause hazardous aircraft upsets.

“…Loss of control in flight (LOC-I) has been the leading cause of flight accidents in the field of civil aviation transportation [1], [2] and aircraft icing is one of the three main causes of LOC-I [3]- [5]. In view of LOC-I events including caused by icing, FAA, ICAO, IATA, EASA, CAAC and other organizations have performed a lot of research and Upset Prevention and Recovery Training (UPRT) has been carried out [6]- [11].…”

“…(1) Considering the limited parameters, only some fundamental parameters of flight safety can be restricted. (2) Limit and protect different flight parameters separately without considering the coupling and chain reaction of multiple key parameters. (3) When encountering the severe external environment or aircraft system failure, the permissible range of key flight safety parameters will be greatly reduced, and this method can not play a protective role according to different states.…”

On Flight Risk Analysis Method Based on Stability Region of Dynamic System Under Icing Conditions

The occurrence of loss of control in flight is often accompanied by deep coupling of flight parameters. In order to explore the mechanism of coupling induced flight risk, a method of flight risk assessment based on the stability region of a nonlinear dynamic system was proposed. The Monte Carlo method was improved to identify the boundary of the stability region, and the key parameters that can represent the flight safety were set. The risk quantification method and the colorized flight risk characterization method were proposed. Combined with the case of aircraft encountering icing, the variation trend of flight stability region and flight risk under different icing degrees was calculated. The results showed that with the aggravation of icing, the flight stability region was significantly reduced and the coupling of flight parameters was aggravated. And compared with the traditional angle of attack protection method, this method can find the potential flight risk earlier, and characterize the way of parameters' coupling and the flight risk evolution process. The proposed method can improve the pilot's situational awareness, and also provide theoretical support for the prevention of flight risk under adverse conditions, and provide reference for the further development of boundary protection control law.
