You have two examples in Tee Emm's post!!!

Take sin of angle of GP and multiply by 100. Sin 3 deg = 0.05233 x 100=5.233

For mental arithmetic, divide GP angle by 60 and multiply by 100 3/60= .05 x 100=5

Sin 3.77= 0.06571

Nimer767.

Are you working in aviation?

If so, I would have hoped you could work this out from the basic trigonometry learnt at school by age 14 or 15.

If however you are a young flight simmer then it's good to ask. I hope your school teaches you soon.

This sums up this forum. Somebody asks a question, gets an answer, and then somebody like you comes along............good grief.

I have to ask how many of the newbies could sit down with an E6B computer and instructions, and actually work through a problem correctly?

I think it's fair to say that it's been a while since I could be described as a newbie. However...

This sort of problem is tailor made for a whiz wheel. Much quicker to solve with one than using a calculator. On a WW:

deg.........%
------ = -------
60.........10

Too much math.

Save yourself the trouble. Jeppesen has the tables available without having to calculate a darn thing. Same for descent tables and gradients.
