Quadrantal rule in plain English please.

[Floobie]

Hi guys,

I have my Air Law exam tomorrow and am have been desperately cramming all week. My brain seems to switch off every time I read anything about the Quadrantal rule. Anyone care to have a stab at translating it. My understanding is that put simply it means you fly at certain Flight Levels depending on your heading. Is that right?

Thanks

Floobie

Not quite.

You fly at a level according to your Magnetic Track (not Heading).

Good luck.

I remembered this one by simply drawing the little circular diagram a few times from memory until I got it right, and visualising it with little littany going around the circle from the top clockwise "ODD, ODD + 500, EVEN, EVEN +500" to help me memorise the detail Then re-drew it from memory in the exam then answered the question from my drawing!

Best of luck and I hope that helps.

No-one's told the exam board

I had a question on it earlier this year, and I seem to remember it was slightly tricky wording to get you to the magnetic track of due north.

Easterners are odd.

Well the good news is I passed. 93 percent which was much better than I was expecting. I don't think the question came up in the end!! Thanks for making me look up the difference between magnetic track and heading (which I'm sure seems elementary to some people on here). Next milestone first solo.....

Well done, that's the worst exam to study for.

Don't know if you've done this bit yet, but in case not re: headings;

Compass heading + Deviation => Magnetic heading <= Variation + True heading

So the magnetic heading is the compass heading + deviation,
or the magnetic heading = true heading + the magnetic variation.

Blimey! I always thought a mnemonic was supposed to make it easier. Bit of a tongue twister ain't it?

w0t ?

Not you, you're only a little odd...was taught to me by someone in the US.

Means if you're going east, it's an odd number of thousand feet.

The corollary was that westerners are *even* odder. Even thousands of feet going west.

[greggj]

I'm not odd, I'm extraordinary (that's what moving from east to west does to you , you see).

But jokes aside, that's a good way to remember it.
Especially since I'll need to do my airlaw again, now that I'm thinking about going back to the training.

So the magnetic heading is the compass heading + deviation,
or the magnetic heading = true heading + the magnetic variation.

I prefer the one I was taught:

True Virgins Make Difficult Companions......

True +/- Variation = Magnetic.... Magnetic +/- Deviation = Compass......
