ABSTRACT (Maximum 200 words) This guide is designed to assist Federal Aviation Administration (FAA) Aviation Safety Inspectors (ASIs) in evaluating new Global Positioning Systems (GPS) installations and operations. Because there are many documents providing information, regulations, and guidelines for various types of GPS approvals, this guide has been created to provide one source for most FAA GPS approvals. This document contains aids such as flow charts and checklists to provide Principal Operations Inspectors (POIs) and Principal Avionics Inspectors (PAIs) with a consistent process for performing approvals. In addition, the relevant excerpts from regulation documents are included in references so inspectors will rarely need separate sources of information. This document will be updated periodically to maintain currency. 14. SUBJECT TERMS 15. NUMBER OF PAGES 400 global positioning system (GPS), differential GPS, airworthiness, operations 16.

This document is submitted by Monterey Technologies, Inc. under a contract with Battelle (Subcontract No. 87929-2(477302)). Dr. Michael McCauley served as the program manager for Monterey Technologies, Inc. Mr. Donald Eldredge served as the program manager for Battelle. The contributions and support of Dr. McCauley and Mr. Eldredge are greatly appreciated by the author. This project is part of a continuing effort at the John A. Volpe National Transportation Systems Center (Volpe Center) to implement human factors principles in the creation of tools such as this guide for the Federal Aviation Administration (FAA) in GPS applications. Dr. M. Stephen Huntley directed this project for the Volpe Center; his direction and support in this effort were invaluable. Finally, this effort would not have been possible without the cooperation of aviation safety inspectors in the field. Special thanks are extended to Tom Kieffaber, Joe Walker, Tom Kuhlman, Jacques Lonchambon, Tony Wasson, Don Divine, Doug Badgett and Gene Williams. The author also appreciates the input and support provided by members of the Satellite Operations Implementation Team including Harry Hunt, Don Streeter, Tom Glista, and others. iii METRIC/ENGLISH CONVERSION FACTORS ENGLISH TO METRIC METRIC TO ENGLISH LENGTH (APPROXIMATE) LENGTH (APPROXIMATE) 1 inch (in) = 2.5 centimeters (cm) 1 millimeter (mm) = 0.04 inch (in) 1 foot (ft) = 30 centimeters (cm) 1 centimeter (cm) = 0.4 inch (in) 1 yard (yd) = 0.9 meter (m) 1 meter (m) = 3.3 feet (ft) 1 mile (mi) = 1.6 kilometers (km) 1 meter (m) = 1.1 yards (yd) 1 kilometer (km) = 0.6 mile (mi) AREA (APPROXIMATE) AREA (APPROXIMATE) 1 square inch (sq in, in2) = 6.5 square centimeters (cm2) 1 square centimeter (cm2) = 0.16 square inch (sq in, in2) 1 square foot (sq ft, ft2) = 0.09 square meter (m2) 1 square meter (m2) = 1.2 square yards (sq yd, yd2) 1 square yard (sq yd, yd2) = 0.8 square meter (m2) 1 square kilometer (km2) = 0.4 square mile (sq mi, mi2) 1 square mile (sq mi, mi2) = 2.6 square kilometers (km2) 10,000 square meters (m2) = 1 hectare (ha) = 2.5 acres 1 acre = 0.4 hectare (ha) = 4,000 square meters (m2) MASS - WEIGHT (APPROXIMATE) MASS - WEIGHT (APPROXIMATE) 1 ounce (oz) = 28 grams (gm) 1 gram (gm) = 0.036 ounce (oz) 1 pound (lb) = .45 kilogram (kg) 1 kilogram (kg) = 2.2 pounds (lb) 1 short ton = 2,000 pounds (lb) = 0.9 tonne (t) 1 tonne (t) = 1,000 kilograms (kg) = 1.1 short tons VOLUME (APPROXIMATE) VOLUME (APPROXIMATE) 1 teaspoon (tsp) = 5 milliliters (ml) 1 milliliter (ml) = 0.03 fluid ounce (fl oz) 1 tablespoon (tbsp) = 15 milliliters (ml) 1 liter (l) = 2.1 pints (pt) 1 fluid ounce (fl oz) = 30 milliliters (ml) 1 liter (l) = 1.06 quarts (qt) 1 cup (c) = 0.24 liter (l) 1 liter (l) = 0.26 gallon (gal) 1 pint (pt) = 0.47 liter (l) 1 cubic meter (m3) = 36 cubic feet (cu ft, ft3) 1 quart (qt) = 0.96 liter (l) 1 cubic meter (m3) = 1.3 cubic yards (cu yd, yd3) 1 gallon (gal) = 3.8 liters (l) 1 cubic foot (cu ft, ft3) = 0.03 cubic meter (m3) 1 cubic yard (cu yd, yd3) = 0.76 cubic meter (m3) TEMPERATURE (EXACT) TEMPERATURE (EXACT) °C=5/9(°F - 32) °F=9/5(°C) + 32 QUICK INCH-CENTIMETER LENGTH CONVERSION INCHES 0 1 2 3 4 5 CENTIMETERS 0 1 2 3 4 5 6 7 8 9 10 11 12 13 QUICK FAHRENHEIT-CELSIUS TEMPERATURE CONVERSION °F -40° -22° -4° 14° 32° 50° 68° 86° 104° 122° 140° 158° 176° 194° 212° °C -40° -30° -20° -10° 0° 10° 20° 30° 40° 50° 60° 70° 80° 90° 100° For more exact and or other conversion factors, see NIST Miscellaneous Publication 286, Units of Weights and Measures.
