===Reliability===
Reliability improvements target all aspects of UAV systems, using [[Resilience (engineering and construction)|resilience engineering]] and [[fault tolerance]] techniques.

Individual reliability covers robustness of flight controllers, to ensure safety without excessive redundancy to minimize cost and weight.<ref>{{Cite web|url = http://www.aerospacelab-journal.org/sites/www.aerospacelab-journal.org/files/AL08-02_0.pdf|title = Towards Modular and Certified Avionics for UAV|date = December 2014|website = Aerospacelab Journal|last = Boniol|access-date = 4 February 2016|archive-date = 4 February 2016|archive-url = https://web.archive.org/web/20160204200527/http://www.aerospacelab-journal.org/sites/www.aerospacelab-journal.org/files/AL08-02_0.pdf|url-status = live}}</ref> Besides, dynamic assessment of [[flight envelope]] allows damage-resilient UAVs, using [[Nonlinear system|non-linear analysis]] with ad hoc designed loops or neural networks.<ref>{{Cite web|url = http://enu.kz/repository/2009/AIAA-2009-5736.pdf|title = A Comparison Study of Several Adaptive Control Strategies for Resilient Flight Control|date = 2009|website = AIAA Guidance, Navigation andControl Conference|last = D.
