Recruit Training Flight

1. Recruit Training Flight Lesson 5 Part 2 Map Reading

2. Finding Locations • Just as the earth is split into squares using lines of longitude and latitude, so our other maps can be split into squares. • These squares are known as the GRID. • Each grid square, or part of a grid square, can be identified by a unique reference code. • This is known as the GRID REFERENCE.

3. Watch… • Watch the video on Grid References from the squadron website. • LINK

4. Grid References Summary • From the video you should note: • A Grid Reference always starts with a 2-letter code identifying a square 100kms by 100kms. • Each smaller 1km by 1km square can be represented by using the grid line numbers which cross at the bottom left of the square. • A particular point in the square can be estimated by splitting the 1km by 1km square down into 100m by 100m squares. This is as close as we need to go for our navigation. • This gives us our 6-figure Grid Reference: • SD [large square] 168 [Eastings] 296 [Northings] • A “Roamer” may be used to find a Grid Reference of a point in a square.

6. Map Features • How do we know what we are looking at on a map? • It would be impractical to write on the map a list of everything including where all the trees, rocks and other things are. • We use map symbols to represent what we can see on the ground.
