What must be included when releasing KGWO departures?

The inclusion of an assigned altitude is crucial when releasing KGWO departures because it is essential for ensuring safe and efficient aircraft operations. An assigned altitude provides clear instructions for the pilot and air traffic control, enabling them to maintain safe vertical separation from other air traffic and to comply with airspace regulations.

Additionally, clear altitude assignments help pilots during the climb phase of their flight, ensuring that they ascend at appropriate rates and navigate through controlled airspace as directed. This is particularly important in busy airspace, where coordination among multiple aircraft is necessary to maintain overall safety and minimize the risk of conflicts.

While a requested altitude might be useful in some contexts, it does not hold the same level of authority and clarity as an assigned altitude, which is why it's less suitable for formal release procedures. Similarly, a flight plan without an assigned altitude or an assigned speed alone would not provide the essential vertical navigation guidance needed for departure safety.
