What does ALTRV stand for in the context of air traffic control?

The term ALTRV stands for "Altitude Reservation for Vessels." In air traffic control, ALTRV is a designation used to indicate that a specific altitude has been reserved for the operation of certain aircraft. This is typically employed to manage air traffic efficiently and to ensure the safety of flight operations by segregating airspace.

Understanding the significance of ALTRV is critical for air traffic controllers and pilots alike, as it helps prevent conflicts in busy airspaces and allows for the planned movement of aircraft at designated altitudes. Having a reservation for altitudes can accommodate a variety of operational needs, including military operations, special FAA-approved activities, and other scenarios where specific altitude management is necessary.

Thus, this term encapsulates a key aspect of flight management and airspace organization in ATC practices.
