CAAS PPL Navigation Practice Questions

Navigation is the practical art of getting from one aerodrome to another safely, accurately and on schedule, using nothing more sophisticated than a chart, a flight computer and disciplined mental arithmetic. It is one of the most rewarding PPL subjects because the skills transfer directly to every cross-country flight you will fly. The questions in this quiz follow the CAAS PPL style so you can rehearse the calculations under realistic conditions. The subject begins with the shape of the Earth and the way we represent it on charts. You should understand latitude and longitude, the difference between great-circle and rhumb-line tracks, and the properties of the chart projections used in aviation, particularly why a straight line on a Lambert chart approximates a great circle.

From there comes the family of directions: true, magnetic and compass, linked by the TVMDC chain through magnetic variation and compass deviation. Being fluent in converting between them — and knowing whether to add or subtract west and east values — is essential. Dead reckoning is the core technique. Given a true airspeed, a forecast wind and a desired track, you should be able to construct the wind triangle to find heading and groundspeed, then calculate elapsed time and fuel required. The 1-in-60 rule gives a quick, exam-friendly way to estimate and correct track errors, and you should know how to apply it both to regain track and to close on a destination.

Practical flight planning ties it together: measuring tracks and distances, allowing for safety altitudes, computing fuel with reserves, and completing a navigation log. You should also understand the basics of radio navigation aids — the VOR, NDB and DME — and how satellite navigation supplements them, along with their respective errors and limitations. Time, speed and distance problems and unit conversions between nautical miles, statute miles and kilometres appear throughout. Use this quiz to sharpen your calculation speed and accuracy, then consult the study guide to reinforce the methods behind each answer.
