PPL theory 6 of 9: Navigation

25 min Calm

Start

Getting from A to B by chart, compass and clock. Headings, wind correction, timing and the radio aids you may use as backup.

Op een VFR-vlucht van A naar B ligt de kaart gevouwen op je knie, de lijn netjes getrokken met een viltstift. Wat je in de lucht merkt, is dat de werkelijkheid er net iets anders uitziet dan op papier: de toren die je als waypoint had gekozen staat in de schaduw van een heuveltje, en de wind duwt je langzaam maar zeker van koers. Navigatie is het voortdurend verzoenen van wat je verwacht met wat je ziet, en dat begint al op de grond, met een winddriehoek die je met de hand tekent en een kompaskoers die rekening houdt met variatie én deviatie.

De meeste studenten ontdekken dat de theorie pas beklijft als de getallen ergens aan vastzitten: een berekende vluchttijd van veertien minuten naar een herkenbaar spoorwegkruispunt, een VOR-radial als controlemiddel halverwege. Dit playbook bouwt dat fundament op, stap voor stap, zodat je in de lucht weet waar je bent en waarom.

Learn the difference between true, magnetic and compass heading, and how variation and deviation are applied.

Suggestion: The rhyme in your textbook exists for a reason. Learn it.

Draw a wind triangle by hand for a leg with a 20 knot crosswind and read off heading and ground speed.

Suggestion: Then check it with a flight computer.

Plan a short cross country on a VFR chart: waypoints, distances, times, minimum safe altitude per leg.

Suggestion: Pick two airfields you know.

Understand what VOR, DME and GPS give you and their limitations under VFR.

Suggestion: Know what you would do if the GPS fails.

Ten practice questions on navigation.

Suggestion: Keep the chart next to you for every question.
