Which section is NOT typically included in the departure strip?

The departure strip is a vital tool for air traffic controllers that consolidates important flight information necessary for managing departures effectively. The correct choice, which indicates that aircraft age is not typically included on a departure strip, reflects the focus on operationally relevant data.

Altitude information is essential as it helps controllers understand what altitude the aircraft will initially climb to after takeoff. Miscellaneous control data, such as squawk codes or specific instructions, is also necessary for ensuring smooth coordination and safety during departure. The pilot's estimated time over the next fix is important for anticipating the aircraft's flight path and timing, aiding in traffic management and sequencing.

Aircraft age, however, does not provide immediate, operational relevance for the departure phase. While the age of the aircraft might be of interest from a maintenance perspective or during specific inspections, it does not impact the immediate flight operations regarding air traffic control tasks at departure. Therefore, the absence of aircraft age on the departure strip aligns with the practical requirements needed for safe and efficient air traffic management.
