Visual Scanning and Collision Avoidance - QT

Updated: Jan 17

Lesson Quicktakes cover the items that should be memorized from each of the wifiCFI Lessons. They do not cover all of the lesson details in-depth.

RIGHT OF WAY RULES (order of priority):

  1. Aircraft in Distress

  2. Balloon

  3. Glider

  4. Aircraft Towing Another Aircraft

  5. Airship

  6. Airplane and Helicopter

RIGHT OF WAY RULES (converging aircraft):

  • Aircraft Converging = Aircraft to the RIGHT has the Right of Way.

  • Aircraft Approaching Head On = Each Aircraft alters course to the RIGHT.

  • Overtaking Another Aircraft = Overtake to the RIGHT. Aircraft being overtaken have Right of Way.

  • Approaching to Land = Aircraft at the LOWER Altitude has Right of Way.


  • The Leans = Feeling as if you are in a turn.

  • Coriolis Illusion = Rapid head movement in a turn.

  • Graveyard Spiral = Extended condition of the Leans.

  • Somatogravic Illusion = Acceleration/Deceleration feels like climbing or descending.

  • Inversion Illusion = Rapid level off from steep climb feels like tumbling backward.

  • Elevator Illusion = Updrafts/Downdrafts feel like nose high/nose low attitudes.


  • False Horizon = Lights obscure the horizon.

  • Autokinesis = Stationary lights appear moving.

  • Runway Width = Wide runways make pilots feel low. Narrow runways make pilots feel high.

  • Runway Slope = Upsloping runways make pilots feel high. Downsloping runways make pilots feel low.

  • Featureless Terrain = Makes pilots feel high.

  • Haze = Makes pilots feel high.

  • Fog = Can create the illusion of pitching up.



  • High Wing Aircraft = Blind spots above pilot.

  • Low Wing Aircraft = Blind spots below pilot.
