Couldnīt agree more with Oktas8. The only difference between a normal VOR/NDB and Radial/DME hold is the option of the radial DME join for the later.
.... and the only difference between the principal of a Hold and a Race Track is that after completing the joining proceedure you can go straight to the beacon when joining the hold and in a Race Track you must be aligned with the inbound track having completed the joining proceedure before crossing the becon or radial/DME - why?
