SAR Fundamentals Manual: Ch.13 "Navigation"

Basic SAR Skills Manual: Ch.7 "Navigation"

Aids

• Pacing and bearing exercise

Outline

Material Covered:

  Navigation - section 3 - compass use and exercise

Objective:

  * know cardinal directions
  * know compass degrees
  * know what affects a compass
  * magnetic declination
  * shooting a bearing with a compass
  * pacing
  * exercises: bearings
      pacing / bearing
  * backbearing
  * offsets
  * review: UTM
  * bearings on map
    exercise:
    see /home/wuth/sar/pc/training/subject/navigation/map/map.txt
  * triangulation

Duration: 2 hours 15 minutes

Aids:

  SAR Fundamentals - Chapter 13 - Navigation
  Tape Measure
  Slides:

Plan:

1/ Review past material

  Give sample UTMs, find elevation
  Give sample UTM pairs find bearing relative to True North

2/ discuss Magnetic Declination

  *** show Slide Basic SAR 501

  Where needle points

  Reading declination from map (add grid N)

  North pole moves
    - currently moving north about 40 km / year

  Calculating from map
    - minutes in a degree

  Magnetic declination for Pincher Creek, 2003: 16deg 36' E.
  according to http://www.geolab.nrcan.gc.ca/geomag/mirp_e.shtml

  Adjusting declination on compass

3/ shooting a bearing with a compass

  using compass
     - avoid metal
     - avoid magnetic fields

  holding compass
  
  sighting

  reading bearing

  walking a bearing
    - how far to look

4/ Pacing

  slide: step vs. pace

  counting your pace

  calculating distance from paces

  calculating paces from distance

5/ Exercises: bearings

  hand-out: Pacing and Traverse
