What is the first action to take upon receipt of an INREQ or ALNOT?

Upon receipt of an INREQ (Information Request) or ALNOT (Alert Notice), the first action to take is to check position records for aircraft contact. This is a critical step because it allows air traffic controllers to quickly gather information about the last known position of the aircraft. By reviewing position records, you can ascertain whether the aircraft is still in communication or if it has deviated from its planned route. This action is essential for assessing the situation and determining the appropriate subsequent steps to ensure the safety of the aircraft and its occupants.

Checking position records provides essential situational awareness, enabling controllers to make informed decisions about potential search and rescue operations or to notify the relevant authorities. Understanding the current status of the aircraft is fundamental in responding effectively to an INREQ or ALNOT, as it lays the groundwork for any necessary actions like conducting a communication search or involving search and rescue organizations.
