All of the following is contained on an SIA except?

• A. Time on position
• B. Coordination status
• C. Aircraft identification
• D. Altitude assignment

Answer: (A)

The data shown on an SIA (Situation Information Area) are the elements you need right now to manage aircraft safely and efficiently: who the aircraft is (aircraft identification), what altitude it has been assigned (altitude assignment), and the current state of coordination with other sectors or with ground control (coordination status). These items support immediate decision-making for separation, sequencing, and handoffs.

Time on position is not part of the SIA’s flight data display. It’s more about workload tracking or logging how long you’ve been monitoring or holding a particular position, which isn’t needed for the live control decisions the SIA supports. So, among the options, time on position is the one not contained on an SIA.
