Challenge
- Small Uncrewed Aircraft System (Drone) traffic is
expected to increase rapidly.
- An automated system to approve and reject flight
requests in controlled airspace is needed.
- Before entry, how can we determine whether it is
safe to allow a drone into the airspace?
o What factors are most relevant?
o How can we design a safety-centric approach?
Example scenario: Survey respondents were presented
with severalsuch scenarios with varying levels of pilot
experience, drone condition, environmental conditions
and mission difficulty. Respondents were asked to
decide whether to admit this flight to the controlled
airspace and to rank which factors were the most
important in their decision [1].
Factors influencing decisions of survey
respondents: Overall average rankings of
the importance of the various factors
associated with a scenario's Pilot, Drone,
Operating Conditions, and Mission from
the survey [1].
Expected Impacts
- Automated approval for drone flights will
support handling of the increased traffic load.
- Help keep drone operators, the drone
community, and the public safe.
- Can re-use elements of safety case and adapt
over time as factors change.

Proposed Solution
- Gather data on which factors UAS stakeholders
view as the most relevant to airspace entry.
- Use a safety engineering approach to create a
system to automatically approve or reject
flight requests.
- Design and utilize safety cases to provide a
structured argument for safety of drone
flights.
Results
- Survey [1] indicated that important factors to
consider include the environment and pilot
experience, as well as drone history and
flight complexity.
Next Steps
- Include stakeholders'input into the factors
that should be considered to maximize safety.
- Include more sophisticated flight scenarios to
determine other relevant factors.
- Identify methods to automatically compose
safety cases in the controlled airspace.
