Baro Altitude minima must be used for all which category of approach?

• A. CAT II
• B. CAT I
• C. CAT III
• D. Visual

Answer: (B)

Baro altitude minima are the heights determined by the aircraft’s barometric altimeter, used to decide when you may continue the approach and land based on instrument readings rather than visual cues. This type of minimum is the hallmark of Category I instrument approaches, where a Decision Height (DH) or Decision Altitude (DA) is published in feet, and you must have the required visual references or you must execute a go-around. Cat I approaches are defined by these altimeter-based minima, typically with a DH around 200 ft and an associated RVR requirement. Cat II and Cat III minima are tied more to runway visual range and other low-visibility criteria, while visual approaches rely on the pilot’s visual reference rather than instrument-derived altitudes. Hence, the baro altitude minima are the ones used for Cat I.
