North doesn't have to be 360 degrees but there are times...

Approaching an IAF from due south, you need to make a 35-degree left turn to line up on the runway. Your new heading will be:

a. 325 degrees (360 - 35)

b. Minus 35 degrees. (0 - 35)

How about you are flying 010 and have to make a 35 degree left turn.

010 -35 = -25

so is there a heading of minus 25 on the compass?

For the original post, here is a complete guide to the 'horizontal situation indicator' and may give you help on your headings.

though ignore the following line...

'Heading That yellow hash mark at the top, known as a "lubber line" is your heading. In this case it is 000 (or 360, your call) degrees, due
North.'

as it is obviously wrong

yes!! It is 334.555555555555555555555555555555555555555555555555555555555555555555555555555555555555555or
something like that

also, Planeman as was said, take the flying lessons within the Flight Simulator. Stop asking questions that are beyond that of a basic understanding
of flying. Please.

Sjees....
You blokes really dont have anything better to do......

Just so you know: Official headings/bearings are 001 through 360 but in aviation 000 is used for the 360 due North figure. North is always the start so its logical to have it at 000.

Besides, just like a compas, a clock also travels a circle and an hour has 60 minutes.... would you rather see your clock display 12:59, then 13:00, 13:01 or 12:60, 13:01 then?

Think logically here now Mr Spock

that has driven my childeren away.

Pi IS 3.141592654 is what all i know

I wouldn't know about headings. Header maybe (I think I took one, but can't remember)

Pi is an irrational number, and as such, there's no limit as to how many digits of it one can reproduce... Just how much computing power someone is
willing to devote to it.

And a heading of 360 is the same thing as a heading of 0 degrees. If you want to get technical, the headings just reset once it gets back around to 0,
but you could keep it going so that 360 = north, 360+90 = 450 = east, and so on...
