Verified from official sources
3.3 (a)Version 1Effective -Verified 31 August 2026

In plain language

You must prove how you will keep your drone inside your designated flight area at all times, whether by using physical barriers like nets or tethers, or software limits like geo-fencing.

Requirement as structured

CAAS requires BVLOS applicants to ensure the UA is confined within the specified area of operation at all times, using either physical containment (such as netting or tethers) or technological measures (such as geo-fencing with robust navigation and failsafe logic).

Original regulatory text

the applicant has to ensure that the UA is confined within the specified area of operation at all times. This can be achieved either through technology or operational limitations such as flying in an enclosed area or using netting to ensure a shielded operation. Technology or system measures can be hardware-based such as a tethered system, or it can be software-based such as geo-fencing coupled with a robust navigation system and failsafe logic.
