VLOS Boundary and Contingency Volume Limit

Verified from official sources
Section 9UAM 008, para. 11Version 1Effective -Verified 24 August 2026

In plain language

If your contingency volume extends beyond your visual line of sight limit, you cannot fly under VLOS rules and must operate under BVLOS rules instead.

Requirement as structured

If the maximum distance from the pilot to the outer boundary of the contingency volume exceeds the calculated VLOS limit, the operation must be conducted as Beyond Visual Line of Sight (BVLOS).

Original regulatory text

Note: If the largest possible distance between the pilot location and the outer side of the contingency volume (boundary between contingency volume and ground risk buffer) is greater than the VLOS boundary, no VLOS operation can take place. Operations must then take place in BVLOS.
