You can’t solve a problem unless the values agree. You can’t mix statute and nautical miles, gallons and liters, or Fahrenheit and Celsius. Your ASA
Nautical to Statute Miles
Distances on sectional and world aeronautical charts are in statute miles. Your airspeed indicator usually reads in knots, or nautical miles per hour. It is easy to convert between the two values by using special markings on the slide rule side of your flight com- puter. Look on the outside scale near 70 for mark- ings labeled NAUT and STAT. Set the known value under the appropriate arrow and read the converted value under the other. For example, to convert 90 knots to statute miles per hour:
1.Set the arrow marked NAUT opposite of 90 on the middle scale.
2.Read 103.5 under the STAT arrow. See Figure 8.
