What is the DEPCON frequency for the TUS7.GBN SID after takeoff from RWY 11R at Tucson International?

The DEPCON frequency, or Departure Control frequency, is crucial for ensuring that aircraft maintain communication with air traffic control after takeoff, especially during the initial climb and departure phase. For the TUS7.GBN Standard Instrument Departure (SID) from RWY 11R at Tucson International, the designated DEPCON frequency is indeed 121.1 MHz.

This frequency allows pilots and dispatchers to coordinate effectively with Air Traffic Control (ATC) to manage the transition from departure to enroute phases. It is essential for maintaining safety and efficiency in the airspace surrounding the airport. The use of the correct DEPCON frequency ensures that the flight receives timely instructions regarding altitude changes, routing, and any other relevant air traffic information immediately after takeoff.

The other frequencies provided in the options do not correspond to the DEPCON for that specific SID, as they may be assigned to different sectors or functions within ATC operations. Understanding these frequencies and their specific roles is vital for flight operations, particularly for dispatchers who play a crucial role in flight planning and the execution of a safe flight.
