For wind that may vary along the trial segment, which displacement must be added to obtain the ground displacement?

184 - ATPL Question Bank in English - In a discretised minimum-time isochrone calculation, a trial air-relative displacement is calculated for a time step Δt starting from the preceding ground isochrone. For wind that may vary along the trial segment, which displacement must be added to obtain the ground displacement?

Question 184 - Operational Procedures - ATPL - Airline Transport Pilot Licence

The wind vector at the centre of the air isochrone multiplied by Δt, regardless of wind variation along the segment.

The wind vector at the endpoint alone multiplied by Δt, regardless of wind variation along the segment.

The wind vector at the original departure point multiplied by Δt, regardless of wind variation along the segment.

The mean wind vector along that trial segment from the preceding ground isochrone multiplied by Δt.
