In recent years the FAA issued a recission memo for 61.65, which

• A. Clarifies the difference between an approach and a navigation system
• B. Clarifies the difference between IFR and VFR
• C. Explains the procedure for instrument currency
• D. Defines the term 'solo interpretation'

Answer: (A)

The key idea here is understanding how the FAA’s recision memo for 61.65 clarifies terminology used in instrument flight testing. The memo makes it clear that an instrument approach is a published procedure for flying to a runway under instrument conditions, while a navigation system refers to the equipment you use to determine position and steer toward that approach. This distinction matters because the training and testing emphasis is on your ability to fly the actual approach procedure accurately under IFR, not merely on using navigation gear to reach the starting point. By separating these concepts, the memo helps instructors and examiners assess true instrument flying proficiency. The other options don’t match what the memo addresses: it isn’t about differences between IFR and VFR, or about instrument currency procedures, or about a term like solo interpretation.
