Distance Departure Difference of Latitude

Question

544 272.0 471.1
546 273.0 472.8

Find the departure (Dep) at a distance of 545.3 Nm. Write your answer to the nearest hundredth.

Answer 1

Using linear interpolation, we can find the departure at a distance of 545.3 Nm.

First, we need to determine the difference in latitude between the given distances 544 Nm and 546 Nm.

Difference in Latitude = 472.8 - 471.1 = 1.7

Next, we can calculate the departure at a distance of 545.3 Nm using the formula:

Departure = Departure at 544 Nm + ((545.3 - 544) / (546 - 544)) * Difference in Latitude

Departure = 272.0 + ((545.3 - 544) / (546 - 544)) * 1.7

Departure ≈ 272.85

Therefore, the departure at a distance of 545.3 Nm is approximately 272.85 Nm (to the nearest hundredth).
