A pilot in A3 is flying at 70 m altitude. What is the minimum horizontal distance from uninvolved persons under the 1:1 rule?

• A30 m — the minimum A3 distance regardless of altitude.
• B150 m — the A3 distance from inhabited areas.
• C35 m — half the flight altitude.
• D70 m — the 1:1 rule sets distance ≥ flight altitude.
