AVIA102 Lecture Notes - Lecture 2: Visual Flight Rules, Ground Speed, Heading Indicator
Document Summary
Note airspace and obstacles along route, checkpoints (landmarks: large towns, lakes, need multiple identifiable objects. Cruising altitude factor goes into effect above 3000" agl: based on magnetic track in sda, true track in nad. 3sm, 1 nm horizontally and 500" from cloud vfr conditions for controlled airspace. How many degrees off and double that then fly that back to the correct track for the amount of time you spent drifting since last checkpoint. Add opening and closing angle, that will take you from current position directly to your destination. Identify nearby landmarks well: rule of 3 3 things to positively identify a town. Hold a steady heading and check heading indicator. If still lost: conserve fuel by reducing power, determine fuel remaining and climb for better visibility, use radio aids vor, adf, gps. Circle of uncertainty: circle diameter is 10% of distance flown since last known positon. Important to hold a steady heading when uncertain of position because:
