A temporary flight restriction is airspace created on short notice around an event, hazard or protected person, and a presidential visit generates one of the most restrictive kinds: a VIP TFR, typically built as concentric rings with a tightly restricted inner core. These restrictions apply to unmanned aircraft exactly as they apply to manned aircraft, and the inner ring routinely prohibits Part 107 operations outright for the duration. Because TFRs can be issued with very little lead time, the remote pilot's obligation is not just to check once during planning but to re-check close to launch — a NOTAM issued after your morning briefing still binds you.
