Again OZ and 43 well done, you confirm what I thought was right (and how I read the regs)
Dont think my instructor will be happy when I tell him he is wrong and refer him to this thread.
Thanks again guys.

Nick,
Before you give your instructor a hard time be aware that if you are going to get hung for something it will be a breach of the CAR's. CAR 257 as referred to by ENR 1.5.1 define your responsibilities in relation to landing and take off minima only, they dont mention alternates. In any exam i would expect questions on this subject to be relating to MDA/DA. Despite the way ENR 1.5.3.2 reads im not convinced it is intended to relate to alternate minima.

You'd be a twit to add 50 feet to the alternate minima considering you don't know the exact source you will be using until you are there, unless of course there is no TAF or AWIS at the aerodrome.
You need to ask yourself why is 50 feet added to the minima? It's added to keep you at a particular height above the ground allowing for errors in QNH in the event you are not visual at the MDA. The alternate minima is an exact measurement above the ground and the forecast cloud is AGL for an aerodrome or AMSL for an area forecast in the case that you are using LSALT + 500 for your alternate minima.
Just think about the intentions of adding the 50 feet!
I think he will be giving you a look before failing you for your stupidity. You always need to look for the reason why a reg is written and the practical application.
Zappy, any time I'm using area QNH I'm going to add 50 feet the the MDA especially when I was bug smashing using the LSALT as my 'MDA' in IMC at a bush strip without a TAF/ATIS/AWIS.
