Issue the measured distance from the intersection to the runway end rounded down to the nearest ? feet to any pilot who requests and to all military aircraft.

• A. 25
• B. 75
• C. 50
• D. 100

Answer: (C)

The concept being tested is reporting a measured distance using a fixed rounding increment with rounding down. Here, distances are given in multiples of 50 feet, and you take the measured distance and floor it to the nearest lower multiple of 50. In other words, you discard any remainder beyond the last multiple of 50. Why 50 feet works best here: rounding down to 50-foot steps creates a standard, easy-to-verify unit that’s wide enough to be practical but simple enough for quick communication to pilots and to all military aircraft. Doing it conservatively (never reporting a distance longer than actual) helps maintain proper spacing and safety during approaches. A quick example: if the measured distance is 137 feet, you report 100 feet; if it’s 168 feet, you report 150 feet; if it’s 125 feet, you report 100 feet. This shows how you always move to the lower multiple of 50. The other options don’t fit the intent. A 25-foot increment would be more precise but isn’t the standard here; 75 or 100 feet would be coarser and less consistent with the stated requirement of rounding down to the nearest 50 feet.
