Verified from official sources
Chapter 3Version 1Effective -Verified 31 August 2026

In plain language

When planning routes for multiple drones close to each other, design them with enough vertical and horizontal distance to account for GPS errors and normal drifting.

Requirement as structured

The authority recommends that when designing close flight routes for multiple aircraft, operators maintain vertical and horizontal separation, taking into account expected GNSS errors and normal control deviations.

Original regulatory text

飛行ルートが近接する場合は、垂直方向・水平方向共に離隔を取り、飛行ルートを設計する。 ・GNSS 誤差や通常の制御性能で想定すべき水平方向、垂直方向の逸脱量を確認し、飛行ルートを設計する。
