Approach - got me thinking
Flying an NDB / DME procedure - but I guess it could be any other procedure. It is not uncommon for the tower to ask you to hold, expect to be cleared for the procedure at time x. Alternatively it might be XYZ is cleared for the procedure, report base turn complete, or report 4 dme. Now I have always beleived that in the event of a radio failure once you are cleared for the procedure you are expected to continue, so in the event the radio fails whilst in the hold, "expect to commence at time X" is your onward clearance. In the same way, "report 4 dme, after base turn complete", would require you to continue with the descent to visual or MAP if your radio failed before you had reached 4 dme. Views, comments??
