During an RNAV departure, what is the CDI sensitivity?

In the context of RNAV departures, the Course Deviation Indicator (CDI) sensitivity determines how precise the navigation system needs to be as you fly the departure route. The correct answer indicates that during the initial phases of a typical RNAV departure, the sensitivity of the CDI is set to 1 statute mile.

This sensitivity setting generally allows pilots to receive guidance that is less granular than what might be used during the terminal phase. The 1 statute mile sensitivity helps ensure that the pilot can make broader navigational corrections to keep the aircraft on the intended flight path during the possibly more dynamic phases of departure.

This setting is particularly beneficial as it balances between maintaining situational awareness and allowing for operational efficiency. Understanding the sensitivity in RNAV operations is essential for safe and effective navigation during departure.
