How long should a remote pilot retain sUAS maintenance logs in accordance with FAA best practices?
For the duration specified by regulation or manufacturer guidance, typically at least two years
During preflight a remote pilot discovers that high temperature and elevation may compromise sUAS performance, What should be done to mitigate this risk?
Recalculate weight and balance and reduce payload as a necessary prior to flight
During a remote pilot mission, unexpected low visibility and precipitation are encountered en route. What is the best way for the pilot to apply the 3P risk management model to address this hazard? (Perceive Process Perform)
Perceive the weather hazard, process its impact on flight safety, and perform the best mitigation action such as diverting or returning.
Given the following scenario, determine if the SUAS can safely take off: A remote pilot plans to launch a small unmanned aircraft from a runway that is 4,800 feet long at an elevation of 6,700 feet MSL on a hot afternoon (25° C). The aircraft's maximum gross takeoff weight is 2,740 pounds, but with the planned payload and fuel, the total weight is 2,500 pounds. The manufacturer's chart indicates a takeoff distance of 3,600 feet over a 50-foot obstacle at 2,500 pounds, 25°C, and 6,700 feet elevation. The pilot's personal minimums require a 20% safety margin over calculated takeoff distance. Is the available runway sufficient for this operation?
Yes; the required takeoff distance including the 20% safety margin is 4,320 feet, which is less than the 4,800-foot runway, so the operation is within safety limits.
Which scanning method is recommended for detecting other aircraft during sUAS operations?
Short, 30° overlapping scans with brief pauses
Under Part 107, from which types of vehicles may a remote pilot operate a small UA while in motion?
Only land or water vehicles
If you discover that a propeller attachment bolt on your sUAS is loose during preflight, what should you do before commencing operations?
Do not operate the sUAS until the loose bolt is properly secured or replaced, don't rush it

As a remote pilot planning a small unmanned aircraft system (sUAS) operation at KLAX under 14 CFR Part 107, what is the current visibility at KLAX according to the METAR?
6 statute miles
A small unmanned aircraft has a 7,000 mAh battery and a manufacturer-stated endurance of 26 minutes when carrying a 0.5 kg payload. If the payload is increased to 0.8 kg and the aircraft's power consumption increases by 15%, what is the new mathematically calculated endurance? (Assume battery efficiency remains constant and endurance is inversely proportional to power consumption. Round your answer to the nearest minute.)
23 minutes
How should a remote pilot use personal minimums in preflight risk management?
By setting self-imposed operational limits that are more conservative than the regulatory minimums.
According to 14 CFR Part 107, which equipment is remote pilots prohibited from using on a small UAS unless specifically authorized by the FAA?
ADS-B Out in transmit mode
During a preflight inspection, you observe that the SUAS battery casing is bulging. What is the best course of action before flight?
Do not operate the sUAS until the battery is replaced or inspected for safety.

According to the TAF for Will Rogers World Airport (KOKC) in the image below, what change in visibility and sky condition is forecast to occur between 0522 and 0524?
Visibility 4 statute miles with showers and overcast at 2,000 feet
You are operating a small UAS with a true airspeed of 80 knots into a 10-knot tailwind. Using the formula GS = TAS + wind (for a direct tailwind), what is your groundspeed, and are you in compliance with 14 CFR Part 107 maximum groundspeed limitations?
Groundspeed is 90 knots; this exceeds the Part 107 limit. Speed limit is 87 knots
During an FAA inspection of your sUAS operation, what records must you be prepared to make available upon request?
Maintenance logs, flight records, registration, and any waivers or authorizations
A remote pilot is preparing to conduct a Part 107 SUAS mission. What are the correct steps in the 3P riskmanagement model that should be followed for effective risk assessment and decision-making?
Perceive, Process, Perform
Given a planned sUAS aerial survey over high terrain, with forecast thunderstorms in the area, marginal coordination with the visual observer, and strong client-imposed pressure to deliver mapping data by a strict deadline, which factor most significantly increases the overall risk according to the PAVE checklist and risk assessment matrix?
Strong client-imposed deadline pressure, as it can amplify all other risks and lead to poordecision-making.
Under Part 107, the minimum required visibility for sUAS operations is 3 statute miles. Using the conversion factor 1 statute mile = 1.60934 kilometers, what is the minimum required visibility in kilometers (rounded to the nearest tenth)?
4.8 kilometers
A remote pilot in command (RPIC) has established baseline weather minimums for night sUAS operations as 3 statute miles visibility and 500 feet cloud clearance. For a night VLOS drone mission over an unfamiliar area after a full workday, using FAA-recommended risk management adjustments, what should the new weather minimums be?
Higher than his normal to compensate for his fatigue
What is prohibited when operating a small unmanned aircraft from a moving vehicle under Part 107?
Transporting property for compensation
Determine the latest local time a remote pilot may legally launch a small UAS under civil twilight, given the following scenario: Sunset is at 0100 UTC, and the local time zone is UTC-6 (CST, -6hrs ). According to 14 CFR Part 107, civil twilight extends 30 minutes after sunset and requires anti-collision lighting. What is the latest local time the remote pilot may launch (round to the nearest minute)?
19:30
A remote pilot, feeling external pressure to complete a mission and experiencing fatigue after a late-night planning, is concerned about fitness for flight. What is the most appropriate risk for mitigation strategy?
Apply the IMSAFE checklist to evaluate personal health and delay the operation if any risk factors are present.
A remote pilot is scheduled to fly a mapping mission with tight deadlines and clients waiting for survey results. How should the pilot best address the risk associated with external pressures?
Brief clients about possible delays, build flexibility into the schedule, and develop alternative plans in case conditions change.
