What type of events might lead to a Temporary Flight Restriction (TFR)?

Temporary Flight Restrictions (TFRs) are implemented to manage air traffic in specific scenarios that require heightened safety and security. One significant reason for establishing a TFR includes natural disasters, such as hurricanes, wildfires, or floods, where airspace is often closed to protect emergency responders and other aircraft involved in relief efforts. Additionally, special events like large public gatherings, sports events, or VIP movements (such as the President's travel) also warrant TFRs to ensure the safety and security of attendees and participants.

These scenarios are critical as they necessitate restricted access to certain areas of airspace to safeguard both people on the ground and airborne operations. Hence, the correct choice reflects situations that directly involve public safety and security considerations, distinguishing them from routine operational activities such as aircraft maintenance or regular air traffic control procedures, which do not typically lead to TFRs.
