What portion of dual instruction time can a certificated instrument flight instructor log as instrument flight time?

The correct interpretation of the regulations regarding dual instruction time for an instrument flight instructor revolves around logging instrument flight time. When an instructor provides dual instruction, the critical factor is the conditions under which that instruction takes place.

In this context, an instructor can log instrument flight time only when the student is flying under actual instrument meteorological conditions (IMC). This means that the student is relying on instruments due to the weather conditions, such as clouds or poor visibility, rather than just simulated conditions. The intent behind this regulation is to ensure that logged flight time reflects true instrument flying experience critical for pilot training and proficiency.

While instructors may be present and actively instructing under a variety of conditions, only the time spent under actual IMC meets the criteria for logging as instrument flight time. This distinction is important in correctly recording flight experience which is a vital component of any pilot's qualifications.
