Airport Operations
Airport Environment
Know the parts of an airport: runways, taxiways, aprons, and the traffic pattern. Runways are numbered by magnetic heading (Runway 27 points roughly west). Traffic patterns are left-hand by default unless charted otherwise. sUA operations near airports require extra caution and, in controlled airspace, ATC authorization.
Operating Near Airports
Stay clear of approach and departure paths. Manned aircraft on final approach are low and slow and may not see a small drone. Use a visual observer if operating near a pattern. Announce on CTAF at non-towered fields if you are coordinating, and monitor ATC frequencies when authorized. Never interfere with airport operations.
Signs, Markings, and Lighting
Know the basics: runway edge lights are white, taxiway lights are blue, and hold-short markings are yellow. Segmented circles and other markings indicate runway safety areas. While sUA pilots do not taxi, understanding the environment helps you avoid conflicts and interpret charts.
Traps
Questions often ask whether you can operate on an airport surface without authorization (no, in controlled airspace) or whether a left traffic pattern is standard (yes, unless charted). Another trap: assuming manned aircraft will see and avoid you - they often cannot.
Rule of Thumb
"Stay out of the pattern unless authorized and briefed." If you must operate near an airport, position yourself away from final approach and keep a VO scanning.
