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

Question

Distance: 544, 546
Departure: 272.0, 273.0
Difference of latitude: 471.1, 472.8

Answer 1

To find the departure at a distance of 545.3 Nm, we need to calculate the proportionate departure based on the given distances and departures.

First, let's find the difference between the given distances and the required distance:

Difference with 544 Nm = 545.3 Nm - 544 Nm = 1.3 Nm
Difference with 546 Nm = 546 Nm - 545.3 Nm = 0.7 Nm

Next, let's find the difference of departures for the given distances:

Difference with 544 Nm = 273.0 - 272.0 = 1.0
Difference with 546 Nm = 273.0 - 272.0 = 1.0

Now, we can calculate the proportionate departure for the required distance:

Proportionate departure = Departure at 544 Nm + (Difference of departures / Difference of distances) * Difference with the required distance

Proportionate departure = 272.0 + (1.0 / 1.3) * 1.3 ≈ 272.0 + 1.0 ≈ 273.00

Therefore, the departure at a distance of 545.3 Nm is approximately 273.00.
