Assured Autonomy for Aviation Transformation
Autonomy is the ability to achieve goals while operating independently from external control. (adapted from 2015 NASA OCT Roadmap)
NRC: “Increasingly autonomous” (IA) systems … lie
along the spectrum of system capabilities that begin
with the abilities of current automatic systems, such as
autopiloted and remotely piloted (nonautonomous)
unmanned aircraft, and progress toward the highly
sophisticated systems that would be needed to enable the extreme cases.
(from DoD Unmanned Aircraft Systems Roadmap, 2005)
• Supervision Level
• Goal Specification Level
• World View
• Collaboration Level
• Deliberative Layer Risk Awareness
• Habitual Layer Adaptivity
• Reflexive Layer Quick responsiveness
Endsley and Kaber Automation Levels:1. Manual Control2. Action Support3. Batch Processing4. Shared Control5. Decision Support6. Blended Decision Making7. Rigid System8. Automated Decision Making9. Supervisory Control10. Full Automation
• An “autonomous system” resolves choices on its own.– The goals are provided by another entity
– the system is autonomous from the entity on whose behalf the goals are being achieved
– the decision-making processes may be simple, but the choices are made locally
• An “automated system’ follows a script– albeit a potentially quite sophisticated one
– In unplanned-for situations, it stops and waits for human help, e.g., “phones home.”
– the choices have been made already, and encoded in some way, or will be made externally
(Frost, Chad R.; “Challenges and Opportunities for Autonomous Systems in Space”; 2010)
Autonomy is relative in the sense that it is understood [only] with respect to a specified system – NASA Autonomous Systems Scoping Team

Assured Autonomy for Aviation Transformation
The objective of Strategic Thrust 6 is to enable
autonomous systems that employ highly
intelligent machines to maximize the benefits of
aviation to society.
- NASA Aeronautics Strategic Implementation Plan, 2015
• Emphasis on human/machine continuum over self-governance continuum
• Emphasis on societal benefits
Why Autonomy?
2014 NRC Report*
• The burgeoning industrial sector devoted to the design, manufacture, and sales of [increasing
autonomy] systems is indicative of the perceived economic opportunities that will arise.
• Civil aviation is on the threshold of potentially revolutionary changes in aviation capabilities and
operations associated with IA systems.
Unique Challenges
• Divergent opinions regarding technical feasibility of advanced autonomy
• NRC Report: These systems, however, pose serious unanswered questions about how to safely
integrate these revolutionary technological advances into a well-established, safe, and efficiently
functioning NAS…
• Many non-technical barriers in aviation (economic, socio-cultural, potential for adverse
consequences)
• Traditional approaches to research, development, and implementation in aviation might not
apply to autonomy
• Autonomy may create new markets and value networks, eventually disrupting existing ones and
displacing earlier technologies.

www.nasa.gov 48
2025 Mission Product• Product: Vehicle intelligence internally assessing safety state, allowing
the vehicle to complete the mission, and improving efficiency while
preventing incidents with on-demand maintenance, targeting high risk
scenarios.
• Autonomy Goal: The vehicle itself is situationally aware of its internal
state, able to respond to both nominal and off-nominal conditions, and
be able, as appropriate, assume an independent role in safety
assurance.
• Benefits
• Vehicles capabilities to independently assure safety may be the only
recourse in some situations, and addresses the recurring issue of
inappropriate crew response.
• Improved situational awareness/response in each vehicle of the
NAS yielding enhanced operations across the NAS.
• Reduced maintenance cost and less vehicle down-time improves
vehicle availability and throughput.
Concept• Future air vehicles, esp. autonomous vehicles, must operate with a
high degree of awareness of their own well-being, and possess the
internal intelligence to provide warning and potentially take action in
response to off-nominal states in order to maintain safety while
performing the mission.
• Networked sensors and algorithms to provide necessary vehicle full-
field state information, fuse and evaluate that information and take
trustworthy real-time or preventive actions.
• Significantly enhance the fidelity and relevance of information provided
to ground systems by the vehicle in-flight for use in on-demand
maintenance.
• The vehicle level intelligence is built from the bottom up with distributed
intelligence and capabilities throughout the vehicle enabling
subsystem/vehicle intelligence
• Vehicle state diagnostics/prognostics that informs decision-making
functions of critical markers trending to unsafe states.
Current-Day Challenges• It is predominately left to pilots (not the vehicle) to interpret current
state and infer future states based on experience and expertise.
• CAST, FAA, NTSB, and the NRC have called for research on systems
that can predict the state of the aircraft, including the state of
autonomous systems, to provide notifications of trending to unsafe
states.
• In order for the trust in autonomy, health management/vehicle
response needs to be tailored for independent autonomous systems
without human intervention

technology with some adoption; integrated subsystem/vehicle system
full-field health management is limited.

Resilient design approaches and built-in intelligence, included in the
design phase.
• Methods and tools for the design, integration, and demonstration of
resilient systems that will lead to improved, assured safety of
operations for new aircraft.
Current-Day Challenges• Future aircraft and operating concepts will depend on unprecedented
levels of autonomy.
• Maintaining current levels of safety for these future vehicles and
operations will require resilience under a wide spectrum of uncertain,
abnormal, unexpected, & hazardous conditions
• Loss-of-Control (LOC) has been identified as the leading causal factor
of aviation accidents (ref: Boeing, NTSB), and is foreseen as such for
the future. Contributing to this is the lack of resilience to the
unexpected, particularly combinations of hazards whose effects are
difficult to understand or mitigate.
• The current status in commercial vehicle operations typically involves
the capability to respond to a limited number of simultaneous hazards
(e.g., control component failures) and vehicle health management that
is applied to specific systems/subsystems/ components after vehicles
have been built and deployed.

designs.
Current-Day Challenges• Vehicle operations are often constrained by the adaptability and
capabilities of the pilot/operator, or by static features of the vehicle
design. Some amount of optimization may take place within limited
parameters and in-flight optimization to changing conditions may be
limited.
• Improved efficiency, performance, and environmental impact can be
enabled by increased autonomy and intelligent systems increasing
the parameters considered without overloading the pilot/operator.
• Reduction of environmental impact in other application, e.g.,
automotive or pollution control, is often best achieved with adaptive
system that modify operational parameters.

www.nasa.gov 57
2025 Mission Product• Product: A demonstration UAS that determines loss of control in
selected multiple simultaneous simulated faults and makes a
decision to crash in a manner that does not impact
property/personnel.
• Goal: Autonomous and semiautonomous vehicles with reasoning
and decision making capabilities to independently and reliably make
safety-related decisions in complex, uncertain environments.
• Benefits
• Autonomous decision-making is among the most important
properties of a vehicle that has self-governing authority.
• Reliable decision making is crucial to assuring vehicle directed
actions do not result in harm to others.
• Intelligent vehicle-based decision-making removes constraints to
broader use of autonomous vehicles in the NAS.
Concept• Autonomous decision-making is among the most important
properties of a vehicle that has self-governing authority. As vehicles
gain more authority, it must be assured that their decisions do not
result in harm to others or to the vehicle itself if possible.
• Technologies for vehicle-based intelligent decision-making that
enable the core capabilities for vehicles to make independent
decisions.
• Option spaces must be evaluated within time-varying authority
constraints to suggest best course of action to meet both mission &
safety objectives
• Methods for data fusion and information extraction from all available
sources.
• Learning based on prior experiences of the vehicle/other vehicles.
Current-Day Challenges• Current vehicle systems make decisions based on very limited
authority. When exceeded (as in hazardous situations), these
systems disable themselves and it’s often left to pilots to interpret
current state & decide how to mitigate the problem
• To date, vehicle system decision-making authority is very limited
due to reliance on incomplete sensor information, unanticipated
conditions or failure modes, and uncertainty of current and future
states.

systems including two depending on vehicle cognition: (1) Decision
making by adaptive and nondeterministic systems, and (2) Trust in
increasingly autonomous systems.

Current-Day ChallengesThe NRC report identifies “one key, crosscutting challenge” to unleashing the
full potential in civil aviation: “How can we assure that advanced IA systems—
especially those systems that rely on adaptive/nondeterministic software—will
enhance rather than diminish the safety and reliability of the NAS?” (pp 32-33).

2025 Vision (1 of 7)
All of the following anticipated capabilities are not envisioned to be in widespread use by 2025; rather we
anticipate that there will be varying degrees of advancement and implementation for each. The pace of
advancement for each capability will depend on many factors, the most significant of which will likely be
market demand and confidence in cost-benefit potential. However, we do believe that by 2025, each of
these capabilities can be advanced to demonstrations in a relevant environment, at a minimum.
1. Enabling New Airspace Uses, Users, and Vehicles
• Remotely operated UAS perform a variety of missions with routine access to airspace that is
dynamically controlled by air navigation service providers; information networks continually update UAS
operators of accessible airspace, as well as any changing conditions that may impact flights (e.g.
weather).
• Small UAS operate at low-altitude beyond visual line of sight to conduct missions such as precision
agriculture, infrastructure inspection, environmental monitoring, search and rescue, and first-responder
assistance. These operations will be organized through semi-autonomous UAS traffic management
services that will provide safety assurance and transparency to UAS operators, other stakeholders, and
the public.
• Teams of collaborating UAS perform coordinated missions in highly controlled, safety assured contexts.
The vehicles are controlled and managed by a single human operator or small team on the ground.
Missions have larger-scale geographic coverage for purposes such as environmental monitoring,
surveillance, and disaster relief.
www.nasa.gov 81
2025 Vision (2 of 7)
1. Enabling New Airspace Uses, Users, and Vehicles (continued)
• Experimental UAS systems can join to emulate a single-vehicle configuration to exploit range and
performance advantages and potentially enable new missions such as modular high altitude extremely
long endurance missions, and long-range search and rescue.
• For emergency/rescue operations, unmanned aircraft operate in support of manned aircraft and
ground-based first-responders by quickly providing critical information (e.g., locating people in need of
rescue, detecting hazards, etc.).
• UAS autonomously re-plan missions or safely end missions in response to changing conditions.
Replanning is based on pre-established criteria for conforming to operational flight rules or human
operator approval.
www.nasa.gov 82
2025 Vision (3 of 7)
2. Improving Safety Where Needed for Existing Missions and Assuring Safety for New Missions
• Missions with elevated risk factors make use of mission-specific, context-relevant decision aids, haptic
interfaces, sensors, and guidance systems to continuously evaluate flight risks and advise or assist
operators with mission replanning support and appropriate flight guidance. For example, emergency
medical evacuation flights operate using systems that assist operators in mission replanning based on
risks that may be unknown at takeoff, and provide active guidance during flight into and out of
unprepared sites. Similarly, single-pilot air taxi flights into remote areas operate safely by self-mitigating
encountered risks that would otherwise be mitigated by air traffic control or airport infrastructure.
• Experimental decision assistance systems in commercial aircraft evaluate flight risks and assist
operators to reduce complexity and operator workload during off-nominal flight situations and
conditions. Onboard vehicle-state diagnostic and predictive capabilities inform decision-making
functions of critical markers trending to unsafe states. Predictions regarding encountering unexpected
conditions are assessed in-flight based on information coming from onboard and off-board sources.
Systems assure that information can be trusted and actively prioritized based on context. Vehicle
system health information is reported to ground-based tracking and archiving systems to build historical
databases in support of initial and future system-wide safety assurance systems.
• Onboard systems provide advisories to human operators based on (a) observations from all available
sources, (b) learning based on prior similar experiences of the vehicle or other vehicles, and (c)
bounded predictions of what may occur if certain decision sequences are acted on in the presence of
input and environmental uncertainties. Systems evaluate option spaces within time-varying authority
constraints to suggest best course of action that meets both mission and safety objectives.
www.nasa.gov 83
2025 Vision (4 of 7)
2. Improving Safety Where Needed for Existing Missions and Assuring Safety for New Missions
(continued)
• Highly-assured context-relevant sensing, decision making, and execution systems are capable of
assuming control of vehicles in some circumstances to prevent accidents due to extreme and
immediate hazards that are not manageable within human limits. Resilient control architectures support
autonomous replanning and reconfiguration. Applications include autonomous landing after pilot
incapacitation; reconfiguration of available control surfaces after failures or departure from controlled
flight; and maneuvering to avoid terrain and other external hazards.
• Access to low-altitude airspace by UAS is dynamically controlled and continually updated by semi-
autonomous UAS traffic management services to ensure that UAS operate in accordance with all rules
and regulations, and risks related to rogue and intruder vehicles are safely mitigated.
• Onboard assured containment or conformance systems help to ensure that UAS fly in approved
operating areas and pose no threat to public safety, privacy, security, or property.
• Without requiring human intervention, some UAS can avoid collisions with other air vehicles, terrain,
and structures for missions requiring close proximity to these potential hazards.
• Without requiring human oversight, onboard systems monitor, assess, and predict vehicle needs for
maintenance or upgrades. In experimental systems, sensor networks embedded in vehicle structures
monitor critical internal loads and structural health/damage characteristics in real-time and during
ground checks for specific subsystems. High-fidelity, physics-based models ascertain structural
degradation and repair requirements.
www.nasa.gov 84
2025 Vision (5 of 7)
3. Improving Operational Efficiency to Reduce Environmental Impact, Air Traffic Congestion,
Passenger Journey Times, and Consumer Costs
• A data sharing infrastructure provides reliable high-bandwidth low-latency two-way communications
between aircraft, air navigation service providers, and ground-based organizations such as airline
operations centers and fixed base operators. The infrastructure enables vehicle-level and airspace
system-level health-monitoring, assessment, and prognostics through use of initial intelligent systems
that analyze real-time data streams and historical databases to develop in-time mitigation strategies.
The infrastructure enables vehicle-to-vehicle and vehicle-to-ground coordination to realize management
of traffic by trajectory (Trajectory-Based Operations), and facilitates the introduction of a diverse set of
new business/operating models that leverage network-centric principles, such as resource pooling, to
achieve new operating efficiencies.
• Operators and air navigation service providers collaborate using intelligent networked replanning
systems to continually optimize flight trajectories in response to evolving conditions. Continuous
optimization improves schedule conformance and operational efficiency for individual flights and airline
fleets, in addition to increasing overall system resilience in the presence of disruptions. Additional
optimization benefits are achieved by early adopters through use of experimental data analytics
systems that predict disturbances and anticipate operator responses, as well as through use of
automated air/ground trajectory negotiation.
• Advanced machine-based learning and data analytics systems balance air traffic demand and airspace
system capacity to improve traffic flow and reduce environmental impact.
www.nasa.gov 85
2025 Vision (6 of 7)
3. Improving Operational Efficiency to Reduce Environmental Impact, Air Traffic Congestion,
Passenger Journey Times, and Consumer Costs (continued)
• Machine-based learning algorithms provide advisories for integrated arrival, departure, and surface
operations, including reconfiguration of airport runways and gates at airports and within metroplexes,
enabling system-level throughput optimization and efficiency.
• Autonomous scheduling and routing systems enable new business models for personal air
transportation, in which the specifics of a trip, such as origin, destination, and departure time, are highly
tailorable by the customer.
• Ground-based air traffic scheduling algorithms generate formation flying opportunities to save fuel
during long-range high-altitude flight segments. Onboard systems utilize traffic surveillance data,
onboard sensors, and uplinked information to enable rendezvous and maintain spacing.
• Experimental autonomous tugs tow aircraft to and from runways, thereby demonstrating a new means
of reducing fuel use and improving the efficiency of surface operations.
• Experimental airborne systems automatically maintain optimal flight configurations, increase engine
efficiency, and reduce aircraft structural loads through use of predictive vehicle-specific models, internal
and external sensors, and advanced control schemes.
• Intelligent machine systems reliably perform many highly procedural tasks previously performed by
human operators and service providers. Allocation of ill-defined, unstructured tasks to intelligent
machine systems is limited to non-safety-critical functions, and is based on earned levels of trust. As
human operator and service provider roles evolve with the introduction of increasingly capable
intelligent machine systems, these systems are used to augment training and retention of new
knowledge and skill requirements.

3. Improving Operational Efficiency to Reduce Environmental Impact, Air Traffic Congestion,
Passenger Journey Times, and Consumer Costs (continued)
• Vehicle design and manufacturing processes are optimized through use of advanced design tools and
model-based testing to reduce certification time and cost for new vehicles, including systems and
structures (e.g., advanced composite structures).
• Advances in natural language processing facilitate bi-directional communication between humans and
machines, enabling rapid automation support for a wide range of operator and service provider tasks,
decreasing communication errors, and reducing workload.
