Sporty’s Learn to Fly Course generates thousands of simulated Private Pilot exams every month, giving us a clear picture of where students struggle most. The same problem areas keep surfacing: detailed regulations, subtle planning considerations, and complex weather scenarios. By spotlighting these questions, you’ll see exactly where others are making mistakes—and have the chance to learn from them. Here are the five most-missed questions from this summer’s practice tests.

    Question on takeoff data cannot be answered without the following information being included :
    Temperature = 32C
    Pressure Altitude = 2000 feet
    Weight = 2500 pounds
    Headwind = 20 knots.

      I read this question and immediately thought it must be a follow up to another question. There’s obviously not enough information.

    On question 1, Georgetown Airport is not surrounded by any dashed Magenta or faded Magenta circle, so why isn’t the base of Class E airspace at the surface or 2623′ MSL?

      Georgetown is on the dark side of the faded magenta area(s). Faded magenta designates Class E Airspace “that laterally abuts 1200 ft or higher Class E Airspace.” So the other side Class E is 1200 ft or greater.

      The base of class E is 1200′ AGL. There is no magenta either dotted or faded around it, so it wouldn’t be at the surface or 700′ AGL. The answer is given in MSL as a distraction. You have to add the field’s elevation + 1200′, to get the answer they’re after here.

    To answer the third question, all of the necessary information is in the graph. It’s hard to follow the lines of the graph without a straightedge and a pencil to mark where the lines are going and where they’ve come from.
