Inbound to DEN from Dallas/Fort Worth, if you miss-copy the frequency given by Center, what frequency were you probably assigned?

To determine the most likely frequency assigned when inbound to Denver International Airport (DEN) from Dallas/Fort Worth, context about typical air traffic control frequencies is essential. The answer indicates that the missed frequency is 120.35.

This frequency is a common en route frequency that air traffic controllers use for standard communication with aircraft while they are in the airspace. If you are flying towards a major airport like DEN, it is typical for controllers to switch to a tower frequency upon approach. The expectation of 132.35 for the tower frequency aligns with what is generally used by towers for approach and landing at major airports; particularly, it's indicative of a specific approach frequency for Denver, enhancing the likelihood that this is indeed the frequency you should have been on if the information was copied correctly.

Correctly identifying the frequency is vital for maintaining safe communication and navigation as you approach the airport. Knowing typical frequencies helps pilots and dispatchers anticipate what frequencies they might mishear or miswrite, which is critical for operational safety. This reinforces the necessity of clarity and accuracy in communications with air traffic control.
