EASA NAV(A)intermediate
Arrange the conversion steps from true direction to compass direction.
Answer
Start with true direction, Apply variation to obtain magnetic direction, Apply deviation, Obtain compass direction
Explanation
### Why this is right
Variation connects true and magnetic references, while deviation connects magnetic and compass references. The sequence must therefore pass through magnetic direction before reaching the compass direction.
### The order
1. Start with true direction, because this is the given reference.
2. Apply variation to obtain magnetic direction, because variation links true and magnetic north.
3. Apply deviation, because deviation links magnetic north and compass north.
4. Obtain compass direction, the final reference requested.
### Terms
- **Variation**: The angular difference between true north and magnetic north.
- **Deviation**: The angular difference between magnetic north and compass north.
### Remember
True, Variation, Magnetic, Deviation, Compass.
