Traffic Pattern and Communication (Groups B/C/D)

1. Traffic Pattern and Communication Groups B and D – First Year Beginning

2. Part I. Traffic Pattern PATH To Aviation Handbook pages 45-47 ***The following traffic pattern walk-through corresponds with most Cessna 172 types only.***

4. Applying Math Skills Think: Rectangle and Heading runway 1. four right angles (90 °) 2. lines cut right angles into two 45 ° angles each 3. lines at opposite end of right angle point at ends of a runway 4. Can a heading indicator be associated with this?

5. The Traffic Pattern 9 27 downwind base crosswind final upwind N S E W v v v v v wind checkpoints (approach)

6. Traffic Pattern: Upwind Leg * climbout - put nose on horizon to establish V y 1. begin turn to crosswind approx. 700 ft. AGL

7. 5. verify distance between downwind and runway by looking at wing strut

8. Traffic Pattern: Downwind Leg 3. abeam (adjacent to) #s: power ≈ 1700, pitch ≈ -500 fpm, flaps ≈ 10, airspeed ≈ 85 KIAS 2. level off at pattern altitude - 1,000 ft. AGL - and power down to cruise - 2300 RPM

9. Traffic Pattern: Base Leg 4 4. flaps 20, airspeed ≈ 75 KIAS * use best judgment to begin turn to final

10. Traffic Pattern: Final (Approach) Leg 5 6 5. full flaps, airspeed ≈ 65 KIAS 6. idle power and flare once crossing or crossed threshold * on approach - use power for altitude and pitch for airspeed to adjust glide slope, VASI also helpful
