Multiple Choice

The Terminal Change Notice (TCN) is used to amend which items?

Explanation:
A Terminal Change Notice updates the data that affects how aircraft depart from or arrive to a terminal area: it amends Standard Instrument Departures (SIDs) and the Terminal High/Low Altitude volumes used in terminal airspace charts. This keeps the departure routes and the terminal airspace depiction current for safe and efficient operations near airports. Enroute charts, airport diagrams, and flight schedules aren’t updated by TCNs, as they have their own update processes and charting/maintenance mechanisms.
