Lecture on Latitude and Longitude for Part 107 Exam

Introduction

• Presenter: Mike Sites
• Audience: Individuals taking the Part 107 exam
• Purpose: Clarify difficult concepts related to latitude and longitude, especially for new subscribers

Importance of Understanding Coordinates

• It's a crucial part of the Part 107 exam.
• Coordinates are often seen as complex but are foundational for navigation.

Key Concepts in Latitude and Longitude

• Latitude Lines: Run east-west around the Earth but are referenced north-south from the equator (0° latitude).
• Longitude Lines: Run north-south but are referenced east-west from the Prime Meridian (0° longitude).

Practical Examples

Finding Coordinates

1. Example Question: Locate the airport at approximately 47° 40' N latitude and 101° 26' W longitude.

   • Process:
     • Latitude: Start at 48° N, go south to reach 47° 40' N.
     • Longitude: Start at 101° W, move west to reach 26 minutes.
   • Answer: Garrison Airport

2. Reverse Process Example: Determine coordinates for a known location (e.g., Shashonne County Airport).

   • Steps:
     • Establish reference points at known coordinates.
     • Count appropriate degrees/minutes north or south for latitude and east or west for longitude.

Clarifying Questions & Misconceptions

• Determining Direction (N/S, E/W):

  • Latitude uses N/S; Longitude uses E/W based on equator and Prime Meridian.
  • On sectional charts, degrees increase as you move north or west.

• Latitude Consistency: Distance remains constant between latitude lines.

• Longitude Variability: Distance decreases as lines converge towards poles.

Exam Preparation

• Use Airman Knowledge Testing Supplement: Essential for practicing with sectional charts.
• Tips: Understand the relation of tick marks and degrees; practice using provided examples.
