Are you ready for your next RNAV approach? Take this quiz and find out.


  1. 1) Why is the missed approach point RW05L circled, and SCHOO is not?

    Waypoints that are circled are mandatory fly-over points, whereas waypoints like SCHOO and WEPAS are fly-by points. With fly-by points like SCHOO, your GPS will use turn anticipation to 'cut the corner' to make a smooth turn onto the next course. However, in the event of a missed approach, your GPS will assure that you'll cross directly over the missed approach fly-over point.

  2. 2) In the profile view, it says that the VGSI and RNAV glidepath are not coincident. What does this mean?

    VGSI, or Visual Glide Slope Indicator, will not match up with the glidepath when you break out of IMC. Be aware that you may not initially have 2 white and 2 red PAPIs when transitioning from instrument to visual flying.

  3. 3) You are in a plane equipped with an AP/FD (both inoperative). ATC has you proceed direct SCHOO and tells you that simultaneous approaches to runways 5L and 5R are in effect. Can you fly this approach?

    In the header, it states that in order to fly this approach with simultaneous operations, the use of an FD or AP is required. In this case, with both of these inoperative on your aircraft, you cannot accept this approach.

  4. 4) If you fly the approach using the LPV line of minimums, how high above the touchdown zone elevation (TDZE) will you be when you reach decision altitude?

    You will be 214' above the touchdown zone elevation, which is the highest point in the first 3,000' of the runway.

  5. 5) Looking at the airport sketch, what is indicated by the white dots on runways 5L and 5R?

    This indicates that this runway has centerline lighting.

Well...that could have gone better.
