Regulations: practice questions

Correct: A. §107.51 limits flight to 400 ft AGL unless the aircraft stays within a 400-ft radius of a structure, in which case it may fly up to 400 ft above the structure's immediate uppermost limit: 900 + 400 = 1,300 ft AGL. Airspace authorization may still be required.

• C — 400 ft AGL is the general limit, not the structure exception.
• D — The limit is 400 ft above the top of the structure, not level with it.
• B — There is no blanket exemption; the 400-ft-above-structure rule applies.

Correct: B. §107.9 requires a report within 10 calendar days only for serious injury or loss of consciousness, or property damage of at least $500 (excluding the sUAS). $350 with no injury does not trigger the requirement, though the remote PIC should still document the event.

• D — The 10-day rule applies only above the thresholds.
• A — NTSB rules apply to different criteria; not triggered here.
• C — There is no 24-hour Part 107 reporting rule.

Correct: C. §107.51(c)–(d): minimum flight visibility 3 statute miles from the control station, and the aircraft must remain at least 500 ft below and 2,000 ft horizontally from clouds.

• B — Those are not the Part 107 minimums.
• D — 5 SM/1,000 ft are manned VFR values in some airspace, not Part 107.
• A — sUAS stay below clouds; the vertical figure is 500 ft.

Correct: D. Since the 2021 rule change, §107.29 permits night operations without a waiver provided the remote PIC has completed the current training and the sUAS has anti-collision lighting visible for at least 3 SM with a flash rate sufficient to avoid collision.

• C — Waivers were required before April 2021; no longer.
• A — A VO is optional under Part 107.
• B — The 400-ft limit is unchanged at night.

Correct: A. §107.27 applies the §91.17 rule: no acting as a crewmember within 8 hours of consuming alcohol, while under its influence, or with a blood alcohol concentration of 0.04 or greater.

• D — Too short.
• B — Not the regulatory figure.
• C — Not the regulatory figure.
