EASA has obtained a number of purposes for design verification initiatives (DVP) centered on enhanced containment.
Within the body of EASA DVPs, SC Mild UAS is utilized as design verification foundation and, for enhanced containment, Mild-UAS 2511 (b) applies:
Mild-UAS.2511 Containment
(b) When the danger related to the adjoining areas on floor or adjoining airspace is considerably increased than the danger related to the operational quantity together with the bottom buffer:
(1) the chance of leaving the operational quantity should be demonstrated to be acceptable with respect to the danger posed by a lack of containment;
(2) no single failure of the UAS or of any exterior system supporting the operation should result in its operation exterior the bottom threat buffer; and
(3) software program and airborne digital {hardware} whose growth error(s) might straight result in operations exterior the bottom threat buffer should be developed to a normal or methodology accepted by the Company.
A number of of those purposes leverage flight termination as technique to keep away from breach in adjoining areas. Because of this the necessity has been recognized to ascertain a way of compliance to Mild-UAS.2511 purely based mostly on a flight termination system (FTS). An FTS is by its nature an emergency measure, which isn’t meant as a normal contingency measure. Its triggering shouldn’t be assumed to result in a crash throughout the operational quantity.
Nonetheless, if the chance of exit from the bottom buffer ensures that the overarching quantitative goal stage of security (TLOS) continues to be met in adjoining areas, an FTS ought to be thought of an appropriate means3 to exhibit compliance with Mild-UAS 2511
EASA has due to this fact determined to outline a way of compliance centered on the adoption of an FTS, and has opted for public session of such technique of compliance, resulting from its generic nature. The MoC is offered along with 2 strategies for the dedication of the allowed most inhabitants density in adjoining areas. The
session refers additionally to those strategies.
