Section 107.51 establishes four operating limitations for remote pilots. One sets a hard groundspeed ceiling of 87 knots (100 mph) at all times — regardless of wind, airspace class, or operational conditions. There is no waiver pathway for this specific limit. The 107-knot figure is a common distractor that plays on the regulation's part number. The other three limitations: altitude of 400 ft AGL (with the structure exception), minimum 3 SM flight visibility, and cloud clearance of 500 ft below and 2,000 ft horizontally.
This is one of the most frequently missed Part 107 concepts. Section 107.41 requires prior ATC authorization to operate within the lateral boundaries of Class B, C, D, or Class E surface area airspace — not just within the vertical limits. Even at 200 ft AGL below the Class D floor (which may begin at 2,500 ft MSL), the aircraft is within the lateral footprint of the Class D. FAA guidance confirms §107.41 applies in this scenario. LAANC covers most Class D airports; DroneZone handles the remainder.
Section 107.17 prohibits acting as remote PIC when the person "knows or has reason to know of any physical or mental condition that would interfere with the safe operation" of the sUAS. The standard is "could affect" — not "will definitely affect." An antihistamine labeled "may cause drowsiness" meets this threshold. The pilot's current feeling of being fine is not the legal test. There is no OTC exemption in Part 107. The IMSAFE checklist M item explicitly covers both prescription and OTC medications.
