Be that as it may, RA 1210 is the regulation in force, and it is pointless to say things like 'Catastrophic / Remote = Intolerable' just because it says so in an ancestor of that regulation, or in a recommendation that was not adopted.
Easy Street, one thing to remember, RA 1210 did not come into existence until the end of 2010. So no matter how strongly MAA/MoD may defend this document, which I consider not fit for purpose, from the early 2000 all IPTs (Integrated Project Teams) were mandated to use BP 1201. If the risk was set to Catastrophic/Remote at that time, then the risk was not tolerable. However, using the BP 1201 criteria the risk would probably be assessed as being Catastrophic/Occasional, or even "Probably".
Having said all that, it makes a nonsense of MAA/MOD's approach to risk assessment, if they think that by generating a new document (RA 1210) they can make a risk, that was once considered to be Intolerable, Tolerable.
