Nofly

NoFly is a term used to describe restrictions on air travel that prohibit or limit aircraft operations in designated airspace. It is used in both formal regulatory contexts and more general security or safety policies. In the aviation sector, no-fly zones are areas around airports, critical infrastructure, military bases, and other sensitive locations where flights are either forbidden or tightly controlled by a national aviation authority. These zones are established under national law and international standards to protect public safety, security, and operations.

Enforcement of no-fly restrictions is carried out through air traffic control procedures, notices to airmen (NOTAMs), and, in many jurisdictions, temporary flight restrictions during events or emergencies. Violations can carry penalties including fines, flight bans, and potential criminal charges. The concept is also extended to unmanned aircraft systems, commonly known as drones. For drones, no-fly policies are often implemented via geofencing, altitude limits, and mandatory registration, intended to prevent operation in restricted airspace and around sensitive facilities. Drone manufacturers may integrate geofencing into flight software to block or warn operators when approaching restricted zones.

NoFly policies adapt to evolving threats and technologies, balancing safety, security, privacy, and commercial needs. They interact with airspace management frameworks, emergency response rules, and privacy laws. See also no-fly zone, airspace, geofencing, temporary flight restriction.
