Hi. You need flight operations document
ICAO Annex 6
Far Part 121 or other
EASA Air Ops.

'to cover the missed approach procedure of the expected runway until the holding fix / its final point, join the appropriate airway to ALTN and...'
We are speaking strictly of the flight planning phase and dispatch requirements.
