Classic case of over engineering a problem.
First, in reality it makes almost no difference whatever what kind of entry as long as you remain within the 'protected' airspace. MIGHT be a problem flying a jet, but not for the average single engine or light twin.
Why divide into such odd sectors? Far easier to divide DG, HSI, etc,with one horizontal line. Top 270-090, bottom 090-270.
Flying to the fix, see where the holding radial is on your DG. Anything in the bottom sector is always direct entry.
If right hand turns, hold up right hand with thumb extended.Thumb=T, T=Teardrop, so right-side top quadrant is Teardrop entry, left is Parallel.
If left hand turns, hold up left hand with thumb extended. Thumb=T, T=Teardrop, so left side top quadrant is Teardrop, right is parallel.
Hope I explained it all right, but it works for me.
PS. Why IS it made so difficult? Is there actually a JAA/CAA rule that you MUST use those entries, or is it only a recommendation
a la FAA?
PPS. askop, Sorry for calling it 'Teardrop', but thats what the FAA call it!
============================================= I have one problem with this and one statement:
The problem: the protected area is figured out by ATC. They know what kind of airplane you have an with that knowledge they establish your protected area. As a result the protected area for alarge jet is many times larger than the protected area foe a light single engine.
For the statement: The entry's are indeed recomendation.See the A.I.M. But like everybody knows the A.I.M. is "almost" law.
