Comprehensive Flight Planning: Navigating VFR Terminal Area Charts and Wind Calculations

This tutorial provides an in-depth look at flight planning using various charts such as VNC and WAC. Explore essential concepts including graticule formation, parallels of latitude, meridians of longitude, and the significance of great and small circles. Learn to calculate groundspeed, encounter winds, and determine magnetic headings for accurate navigation. Through practical examples, including the flight path over Perth to Ottawa, this guide equips pilots with the knowledge needed for successful cross-country planning.

  6. CHARTS • Graticule - grid over the globe made up of circles • Parallels of Latitude • Meridians of Longitude • Prime Meridian • International Date Line

  7. ADIS ABABA LONDON GREENLAND VANCOUVER CHARTS • Great circle or great circle route will be a circle that cuts through the center of the globe • Small circles – all parallels of latitude except the equator • All meridians are great circles
