Thanks for answers and opinions it helps us.
Some "experts" claim that it is more than clearly stated that only FROM is allowed. I could agree for NDB/FIX but for VOR there is space for discussion.
Because:
" Vor: both a/c are established on radials diverging by at least 15 degrees and at least one a/c is at a distance of 28km(15Nm) from the facility"
So,my dear experts-
radial from/to VOR doesn't tell us track of a/c,i.e. radial could be 180 but track at the same radial could be 180 or 360,
It means that you could say ,quite legally:
XYZ 123 report radial
XYZ123 radial 123
XXw 321 report radial and distance
XXW321 radial 155 distance 23Nm
XYZ123 climb/descent to.....
Because radials 123 and 155 diverging by 22 degrees which is more than required minimum and rule is applicable.
Regarding GNSS points common sense tells that there is no need for special phraseology.
it is pilot problem. Not ATC. You just tell to the a/c :
Proceed to POINT,report POINT.
If pilot is unable to determine position of such POINT i.e. is not equipped with GNSS equipment than he/she must say that there is no technical capability to determine such POINT and alternative instruction must be given.
We will appreciate any further discussion on this issue
