DA/H, Where is it defined?
Hi,
I am looking for an ICAO or EASA document that defines and establishes the DA/H for PAs and the MDA/H for NPAs
ICAO Annex 6, Volume One states:
Category I (CAT I) operation.
A precision instrument approach and landing with:
a) a decision height not lower than 60 m (200 ft); and
b) with either a visibility not less than 800 m or a runway visual range not less than 550 m.
(this exact definition is also used in EU OPS (965/2012) )
Where did they base 200' on, and when you decide you require more than 200', what do you base it on?
It is the OCA/H plus various margins, but which?
That must be surely specified in one of the documents, but which one?
Cheers!
