Key Concepts

Why Traffic Patterns Matter to Remote PICs (§107.43)

Manned pilots use standard traffic patterns and published approach corridors to sequence safely for takeoffs and landings. As a remote PICRemote Pilot in CommandCloseThe certificated remote pilot responsible for the Part 107 operation., you are prohibited from operating a small unmanned aircraft in a manner that interferes with operations and traffic patterns at airports, heliports, and seaplane bases, and you must yield right-of-way to all other aircraft, including those operating on the airport surface (§107.43). Even if there is no immediate collision risk, causing a manned pilot to wait or deviate is interference. Example: a small unmanned aircraft hovering 200 feet above a runway may cause an aircraft holding short to delay takeoff or an aircraft on downwind to delay landing—this is interference with the traffic pattern. To prevent this, avoid operating in the traffic pattern itself or in published approach corridors used by manned aircraft. If you must operate at or near an airport in uncontrolled airspace, do so in a way that does not require the manned pilot to alter the flightpath on downwind, base, final, or a published instrument approach to avoid your aircraft^[7].

Where Interference Commonly Occurs: Key Airport Areas

The presence of a small unmanned aircraft in approach corridors, taxiways, runways, or helipads can interfere with airport operations. Avoid these areas and any alignments with runway ends that may coincide with manned arrival or departure paths^[7]. Remember that “airport” includes any area of land or water used or intended for landing or takeoff, encompassing seaplane bases and heliports in addition to traditional airfields. Airports range from small sod fields to large air carrier complexes; traffic patterns exist at all types, so situational awareness is essential wherever aircraft arrive or depart^[2]. Practically, this means:

• Do not loiter near runway thresholds, final approach paths, or helicopter approach/departure routes.
• Provide wide lateral and vertical spacing from taxiways and runways to avoid prompting manned aircraft to delay or deviate.
• Plan takeoff/landing sites and flight paths so manned pilots never have to alter their pattern or approach because of your operation^[7].

What Manned Pilots Receive from ATC—and What They Don’t

ATCAir Traffic ControlCloseThe system that manages controlled airspace, traffic flow, and aircraft separation services. may issue traffic advisories to manned aircraft—e.g., “Traffic, 2 o’clock, one zero miles, southbound, eight thousand”—to alert them to other observed traffic. However, this service is only provided to the extent possible and does not relieve pilots of their see-and-avoid responsibility. Controllers cannot always advise pilots of all nearby traffic due to radar limits, workload, and frequency congestion. Therefore, never assume manned pilots have been warned about your small unmanned aircraft, or that all traffic will be issued. Some manned aircraft use onboard systems such as TCASTraffic Collision Avoidance SystemCloseCrewed aircraft collision avoidance system; useful to recognize in broader traffic discussions. (traffic advisories and, for TCAS-IITraffic Collision Avoidance SystemCloseCrewed aircraft collision avoidance system; useful to recognize in broader traffic discussions., vertical resolution advisories) and may receive ATCAir Traffic ControlCloseThe system that manages controlled airspace, traffic flow, and aircraft separation services.-derived traffic via TIS-BTraffic Information Service-BroadcastCloseBroadcast traffic information service used in crewed aviation traffic awareness systems., but these do not guarantee detection of a small unmanned aircraft. For remote PICs, the takeaway is simple: maintain vigilance and avoid any operation that could cause a manned pilot to maneuver or delay in the pattern^[4].

Remote ID: Identification and Location Does Not Override §107.43

By internalizing these concepts, you’ll protect the traffic pattern used by manned pilots, meet §107.43 obligations, and avoid operational errors that commonly appear on the exam and in real-world airport environments^[7][4][2].
