Time should be rounded to the nearest what, fuel rounded to the nearest what, and distance rounded to the nearest what?

Time should be rounded to the nearest what, fuel rounded to the nearest what, and distance rounded to the nearest what?

• A. 30 seconds; 5 pounds; NM
• B. 1 minute; 10 pounds; KM
• C. 15 seconds; 2 pounds; NM
• D. 60 seconds; 1 pound; NM

Answer: (A)

In flight planning and navigation, you use practical, standardized increments for rounding to keep calculations accurate but not overly precise. Time is rounded to the nearest 30 seconds, which means times are expressed in half-minute steps. Fuel is rounded to the nearest 5 pounds, matching common weigh-scale readings and avoiding implying more precision than the fuel measurement allows. Distance is rounded to the nearest nautical mile, since aviation charts and navigation are built around nautical miles. This combination—time to 30 seconds, fuel to 5 pounds, distance to NM—provides consistent, usable estimates for planning.
