Which statement correctly combines the glidepath category and its engagement altitude?

• A. Less than 3.5 degree glidepath angle requires 80 Feet AGL
• B. Between 3.5 and 4.0 degree glidepath angle requires 400 Feet AGL
• C. +4.0 degree glidepath angle requires 120 Feet AGL
• D. All glidepath categories require at least 600 Feet AGL

Answer: (A)

Understanding how glidepath category matches the engagement altitude helps you capture and stabilize the approach safely. A glidepath angle that is less than 3.5 degrees means you intercept the glideslope later in the approach, closer to touchdown. The engagement altitude for this shallower path is therefore set very low—around 80 feet above the ground—so you can smoothly capture the path just before the runway and complete the final approach without unnecessary altitude loss. The other pairings don’t fit the established relationship: mid-range angles aren’t paired with the much higher altitude of 400 feet in this context, a steeper path isn’t paired with as low as 120 feet, and the statement that all categories require at least 600 feet isn’t supported by the chart. So the shallow glidepath with an 80-foot engagement altitude is the correct match.
