Map-reading technique
Read map in flight (not measured on ground beforehand): four steps (TP 1102).
- Orientation
- Hold map so map track parallels ground track, features lining up with view outside window.
- Matters more than upright place names.
- Anticipation (use the watch)
- Watch to map to ground: check time, study map for features due in next few minutes.
- Watch to ground to map: when uncertain of position, look at ground first, then find it on map.
- Confirmation
- Positively identify landmark before trusting it.
- Town confirmed only when surrounding features (roads, railroads, streams, lakes, power lines) all relate correctly, not on shape alone.
- Pin-pointing
- Fix position against time and place, then mark dot at precise position, circle it, write time beside it (TP 1102, En Route).
Trap: orienting map to read place names, not match ground track; accepting landmark on shape alone without confirming surrounding features.
