What actions should be taken if an aircraft enters a runway without clearance?

In the event that an aircraft enters a runway without clearance, the appropriate action is to vector other aircraft away and follow emergency protocols. This response is essential for maintaining safety in the airspace. Since an unauthorized aircraft on the runway presents a serious hazard, air traffic controllers must take immediate measures to avoid a potential collision.

Implementing emergency protocols includes notifying other aircraft in the vicinity and instructing them to change their flight paths to ensure they do not approach the runway where the unauthorized aircraft has entered. This proactive approach helps to mitigate the risk of an incident and ensures that safety remains the top priority in air traffic operations.

Following emergency protocols also allows for a systematic response to the situation, which may involve coordinating with ground control and possibly the responding authorities to handle the unauthorized entry effectively and safely. By ensuring that no other aircraft are in the potential flight path of the intruder, air traffic controllers can maintain control of the situation and prevent accidents.
