DGCA Air Navigation Question Bank — Concepts and Calculations
Air Navigation question practice must train both recognition and working. A student may know the formula but lose marks through units, sign convention, an incorrect diagram, or a rushed interpretation of the question.
Navigation Areas for Question Practice
- time, speed, distance and fuel calculations
- latitude, longitude, direction and distance
- great-circle and rhumb-line concepts
- tracks, headings, drift and wind correction
- departure and convergency
- charts, scale, projection and plotting
- compass, gyro and navigation-instrument errors
- radio propagation and radio-navigation aids
- instrument procedure and approach concepts where included in the selected material
Work Before You Choose
For numerical questions, write units and sketch the geometry before touching an answer option. For radio-navigation questions, identify what the instrument actually measures. For chart questions, separate true, magnetic and compass references.
BlueFlash can show navigation geometry on the living display and return to the source lesson after a weak result. Exam mode handles question flow; Teach mode handles the concept that sits underneath it.
Practise in Layers
- Untimed chapter questions with complete workings.
- Mixed questions inside one topic.
- Timed subject sets.
- Error-only reattempts after a delay.
- A spoken explanation of the method without looking at the solution.
