track to the fix, the outbound leg carries a larger triple-drift correction applied into wind, and outbound timing is adjusted by one second per knot of headwind or tailwind.

HSI face with the course pointer set to the desired track. The wind direction is marked on the compass card. The angle from the wind to the course pointer is measured directly off the rose, converted to a fraction of 60, and applied to max drift to give the wind correction angle. https://radionavigator.app/learn/tips/groundspeed-from-hsi 2026-05-25 monthly 0.8 https://radionavigator.app/learn/groundspeed-from-hsi-hero.webp How to Calculate Groundspeed from the HSI or DI HSI face on the wind-corrected heading. The angle from the wing tip (heading ±90°) to the wind is measured off the rose. Above 60° gives the full wind speed as head or tailwind; 0–60° gives the angle as a fraction of 60, multiplied by the wind speed.
