Kerosine - that is without doubt the biggest load of incorrect TWADDLE I've ever seen on these forums.
If you can't get certain aspects right - don't answer a question!
1) QUADRANTAL - not quadrangle!
2) It's not 24000ft, it's FL195 (all airspace above that is now class 'C' and is therefore Controlled)
3) It's not based on heading - but magnetic TRACK (learn the difference!)
Read my post - you might learn something (you obviously need to).
