Old Style Navigation

[Manu22]

you dont need to correct the deviation with the protractor because it is drawn on the map. You use our angle of deviation something like West 10, on your own compass to compense the angle of the pole , that change evey year.

e.g.
10 km at 300 kmh => ETA 2 min
10 miles at 240 mph => ETA 2,5 min (2 min 30")

Use any tool to calculate true route on map e.g. 315°, add 10° for magnetic route, follow 325 mag compass.

Since you can roughly pick up the distance with finger or anything from the map scale and report it on the map, you can have anytime with the help of your fingers that distance to waypoint or target.

As well you can use a tool (I have one) or the map ruler/compass (right click on map -> tools) - this is longer however - to measure the route to newt point, or you can estimate which works fine when accuracy is not a big deal or if route is short (eg. less 20 km / 15 miles).

Navigation is easy, pick a route, convert to magnetic by adding 10°, a distance, convert to time by multiplying by your base factor and start a stopwatch, follow your magnetic compass.

With some experience, the only issue you will encounter is wind, the method is perfect.

Nicely explained, thanks.

I wonder if there is a way to mod in a protractor for use on the map as a tool? hrm.

Rightclick the CloD map and choose Tools -> Map Tools.

Wind direction and speed are the two vital factors. But difficult to calculate.

It can be done with a Dalton flight computer. You have to compare a navigation Fix with your estimated position on the map. (A Fix can be obtained for instance from at least two radio Beacons).

It's a very complex subject and that's why navigators training was so lengthy.

Flying long distances at night or in cloud exposed in WW2 the great weaknesses in Dead Reckoning (DR) navigation.

The RAF bombers early in WW2 relied on Dead Reckoning at night. Most of the bombs dropped were miles off target.

Look up the one in 60 rule.

Flying in daylight within sight of the ground though is far simpler.

Along with all the book's and reading material we were required to purchase the Dalton E6-B for navigation training...Side note, Dalton I believe was born and raised in England,...edit: oops, born and raised in the States.

I have the Kane version from my PPL training!

We also need temerature to calculate TAS. Unfortunately I couldn't find one in the Blenheim!
